SAFETY SUMMARY
The folio ~/ng general safety precautions must be observed during all phases of operation, service, and repa r of this Instrument. Failure to comply with these precautions or with specific warnings elsewher~ In this manual violates safety standards of design, manufacture, and Intended use of the
tnstrume, t. Hewlett-Packard Company assumes no liability for the customer's failure to comply
with thes requirements.
GROUN[ THE INSTRUMENT. To minim ze shock hazard, the instrument chassis and cabinet must be connected to an electrical ground. he instrument is equipped with a three-conductor ac power cable. The power cable must eith sr be plugged into an approved three-contact electrical outlet or used with a three-contact to two-cc ntact adapter with the grounding wire (green) firmly connected to an electrical ground (safety g ound) at the power outlet. The power jack and mating plug of the power cable meet Internatior al Electrotechnical Commission (lEG) safety standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE. Do not operate the instrument in the presence of flammable gases or fumes. Operation of any electrical nstrument in such an environment constitutes a definite safety hazard.
KEEP A¥. AY FROM LIVE CIRCUITS. Operating personnel must not remove instrument covers. Component replacement and internal adjustmerts must be made by qualified maintenance personnel. Do not replace components with power csble connected. Under certain conditions, dangerous voltages may exist even with the power cc ble removed. To avoid injuries, always disconnect power and discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE. Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscttatlon, is present.
USE CAl TION WHEN EXPOSING OR HANDLING THE CRT. Breakage of the Cathode-ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To preve t CRT implosion, avoid rough handling or jarring of the instrument. Handling of the CRT shall be done cnly by qualified maintenance personnel using approved safety mask and gloves.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT. Because of the danger of introducing additional hazards, do not install substitute parts or perform any una Jthorized modification to the instrument. Return the instrument to a Hewlett-Packard Sales anc Service Office for service and repair to ensure that safety features are maintained.
DANGEROUS PROCEDURE WARNINGS. Warnings, such as the example below, precede potentially dangerous procedures throughout this
I I manual. Ir structions contained in the warnings must be followed. WARNING

General Information

SECTION I GENERAL INFORMATION

1-1. I TRODUCTION.
1-2. s manual provides operating and servicing infonna .on for the Hewlett-Packard Model 18Zf Oscillos ope. The manual is divided into eight sections, each co ering a specific topic or aspect of the instrument. schematics are located at the rear of the manual
1-3. is section contains instrument specifications (table 11), a description of features, warranty information, data for manual and instrument identification, and in rmation regarding accessories available for the ins ment. Table 1-2 describes the abbreviations used in this manual except for Section VI. The parts list co tains a computer printout using computer supplie abbreviations.

1-4. ESCRIPTION.

1-5. e Model 18Zf is a solid-state, lightweight laborat ry and general-purpose oscilloscope mainframe ith plug-in capabilities. It is designed to display c plex high-frequency waveforms and to measure al mating- and direct-current voltages. Complete specifi ations are given in table 1-1.
e Model 18Zf is a cabinet-type instrument built-in tilt stand, carrying handle on top, t mounted on both bottom and rear for either r upright operation.
1-7. P wer consumption, with plug-ins is less than 120 w tts at normal line voltage. The instrument is conve 'on cooled and designed to operate within specifi ations at temperatures between O°C and 55°C with u to 95% relative humidity at 40°C.

1-8. e instrument contains all power supplies, a

dual-o tput calibrator, a horizontal amplifier, a gate

ampli er, and the CRT. Operation at either 115- or

230-V c is selectable by a switch located on the rear

panel of the oscilloscope. Also located on the rear

panel are. recorder output connectors for use with

spect

analyzer plug-ins. These outputs are

depen ent upon the spectrum analyzer used and the

appro riate plug-in Operating and Service Manual

shoul be refered to.

NOTE

ese outputs should not be used when standard 18DO-series plug-in is used.

1-9. The Model 182T is designed to operate with real-time, sampling and TDR, and frequency domain plug-ins.
1-10. A calibrator provides a square-wave signal of approximately 1 kHz with a rise time of less than 3 IJ,s. The calibrator output is available at the front panel at amplitudes of 250 mV and 10 V POp with an accuracy of ±1%. The signal may be used to check horizontal and vertical deflection factors and to compensate divider probes.
I-II. The oscilloscope horizontal amplifier accepts sweep signals from the time-base plug-in or an external signal. Bandwidth is de to 5 MHz, de-coupled, and 5 Hz to 5 MHz with capacitive coupling. Two deflection factor ranges are front panel selectable: 1 V/div (Xl), and 0.1 V/div ±5% (X10). In addition, a vernier control provides continuous adjustment between ranges. The maximum external input level is 300 Vde, ac-coupled, with a dynamic range of ±20V.
1·12. A beam finder pushbutton control assists the operator in bringing a displaced beam on screen. Its use increases intensity and reduces vertical and horizontal amplifier gain to quickly locate trace position.
1-13. CATHODE-RAY TUBE.
1·14. The Model 182T uses a post-accelerator aluminized CRT with an 8- by 10-major division display area of 133 cm2· Each division is 1.29 em with 0.2-division subdivisions provided on the major axes. The internal graticule eliminates display parallax. The standard CRT supplied with this instrument has a P-39 aluminized phosphor.
1-15. WARRANTY.
1-16. This instrument is certified and warranted as stated on the inside front cover of this manual. The CRT is covered by a separate warranty. The CRT warranty and warranty claim form are located at the rear of this manual. Should the CRT fail within the time specified on the warranty, fill out the failure report form on the reverse side of the warranty statement and return it with the CRT in accordance with the shipping instructions. In all correspondence with a Hewlett-Packard Sales/Service Office concerning an instrument, reference the complete serial number and Model of the instrument.
The warranty may be void for instruments having a missing or mutilated serial number tag.

SECTION III OPERATION

3·1. I TRODUCTION.
3·2. Th s section provides general information on the ope ation, function, and application of the instrument c ntrols. Front- and rear-panel controls and connect rs are identified and briefly described in figure 31.
3-3. G NERAL. The Model 182T is designed to operate with real time, sampling and TDR, and frequency domain plug-ins. These plug-ins are accommodate in the lower portion of the instrument. The requir operating power is obtained from the oscilloscope ainframe. Refer to the plug-in Operating and Service Manual for mating and installation instructio s,
3-4. P SHBUTTON SWITCHES. These switches are two pos tion pushbutton type. They are: MAGNIFIER, DISP Y, and EXT COUPUNG. The pushbuttons for these fu ctions are color coded to indicate the function selected When the released position is selected, the white s irt of the pushbutton is exposed. This corresponds t the control function on the panel outlined in white. or example: if MAGNIFIER is pressed, only the bla k portion of the pushbutton is visible. Magnification is therefore X10. When MAGNIFIER is released, the hite skirt of the pushbutton can be seen and magnifi ation is Xl.

Rotate the SCALE control counterclockwise to OFF when graticule illumination is not needed.
3-9. TRACE ALIGN. This screwdriver adjustment compensates for external magnetic fields that may affect alignment of the horizontal trace with the graticule. Use it to position the trace parallel to the graticule horizontal lines. The alignment should be checked when the instrument is moved to a new location and adjustment made whenever necessary.
3-10. FOCUS AND ASTIG. These controls are used to obtain a display of uniform focus. Adjust both controls for the sharpest display possible.
3-11. FIND BEAM. Occasionally the CRT beam may be driven off-screen by large de input levels or improper control settings. Pressing the pushbutton increases intensity and reduces horizontal and vertical amplifier gains enough to always return a displaced beam to the viewing area. This enables the operator to determine the action necessary to center the display. All operating controls function while the FIND BEAM control is pressed. For example, obtaining a centered display may require adjustment of the deflection factor, horizontal and vertical position, coupling, trigger level, or intensity. If the controls are properly set, the display will remain visible when FIND BEAM is released.

operating controls and front-panel adjuste identified and described in figure 3-1. The followi g paragraphs explain the function of some of the con rols and connectors in detail.
3-7. C L1BRATOR. The calibrator has two outputs, 10 V a d 250 mV peak-to-peak, negative-going from ground, with an amplitude accuracy of ±1%.The output is squ e wave at a frequency of approximately 1 kHz. Rise . e of the signal is less than 3 microseconds. These 0 tputs are useful for checking vertical and horizontal ensitivity calibration, and divider probe calibration A 3-way binding post provides a ground connection point and may beused with banana plug, wire, or spad lug connection.
3-8. S ALE. This control adjusts the overall brightness of the CRT graticule. It should be adjusted for good c ntrast between the background and the graticule. e SCALE control is useful when using a hood to view the display or when photographing waveforms.

3-12. LINE. This toggle switch applies or removes ac line input power to the instrument. When ON, an indicator lamp, located immediately above the switch, is illuminated. Power for the lamp is obtained from the low-voltage power supply. Both sides of the ac power line input are interrupted when switched to OFF.
3-13. COUPLING. The EXT COUPUNG switch is used to select ac coupling (capacitive coupling) to the amplifier for alternating voltages or de coupling.
3-14. HORIZONTAL MAGNIFIER. This pushbutton switch controls the gain of the horizontal amplifier. When switched from Xl to X10, the gain is increased ten times. For example, one volt into the horizontal amplifier EXT INPUT jack produces 1 division of deflection in Xl and 10 divisions of deflection in X10.
3-15. HORIZONTAL DISPLAY. Either of two modes of operation can be selected with this switch. It selects the origin of the input signal applied to the horizontal amplifier. When INT is selected, the input signal to the horizontal amplifier is obtained from the plug-in. With the switch in EXT, the sweep signal input from

Theory

SECTION IV PRINCIPLES OF OPERATION

4-1. I TRODUCTION.
s section provides circuit theory analysis of I 182T oscilloscope. Refer to the overall block (figure 4-1) and the schematics in Section
4-3. ENERAL DESCRIPTION.
4-4. T Model 182T is an X-Y axis display instrument de igned for use with real time, sample and TOR, and sp ctrum analyzer plug-ins. The instrument contai the CRT and its controls, low voltage and high v ltage regulated power supplies, a horizontal amplifi r, and a gate amplifier.
4-5. To obtain a useful display on the CRT, three signals are necessary: vertical deflection, horizontal deflecti n, and intensity. The signal required for vertical deflection (Y-axis) of the CRT is supplied by the lug-ins. This signal is connected directly to the CRT ve ical deflection plates. The horizontal (X-axis) deflecti n signal is also generated by the plug-ins. It is fu her amplified by the oscilloscope horizontal amplifi r before being applied to the CRT horizontal deflecti n plates.
4-6. A unblanking gate signal, synchronized to the start 0 'the horizontal sweep, is developed in the plug-in and amplified by the gate amplifier. The signal from the CRT control grid, unblanking the viewin area of the CRT.
4-7. S' nals for horizontal deflection and intensity modul .on can also be applied to the oscilloscope from n external source other than the plug-ins. Extern I input jacks are provided for this purpose.
4-8. I PUT POWER. With power applied to the power transf er primary windings, several secondary voltag s are produced. They are rectified, filtered and regula ,as required, and used as the de source of power or the various circuits of the oscilloscope and for ope ation of the plug-ins.
4-9. ORIZONTAL DEFLECTION. The horizontal ampli er may be used with either internal or external si al sources. Positioning the HORIZONTAL DISP Y switch to INT arranges the circuitry to opera from signals supplied from the plug-in. In this ndition, -100 V is applied to the plug-in. allowi g it to operate and produce both a sweep signal and a unblanking gate signal.

4-10. The sweep signal from the plug-in is coupled to the oscilloscope horizontal output amplifier where it is converted to a differential signal, amplified, and applied to the CRT horizontal deflection plates.
4-11. Horizontal position of the X-axis sweep signal is controlled at the input stage of the horizontal output amplifier. A two section potentiometer, mechanically interconnected, is used to provide both fine and coarse positioning controls from a single knob.
4-12. Horizontal amplifier gain is controlled by the MAGNIFIER switch. Two settings can be selected: Xl or X10. With Xl selected, the sweep speed corresponds to the selected plug-in sweep speed. In X10 operation the sweep speed is ten times that selected at the time base plug-in.
4-13. The unblanking gate signal from the plug-in is coupled to the gate amplifier where it is summed with the current from the INTENSITY control. The resulting signal is amplified and coupled through the high voltage supply to the CRT control grid to set the intensity of the displayed signals.
4-14. An externally applied signal for horizontal deflection may be connected to the EXT INPUT jack. The EXT VERNIER controls the externally applied signal and provides a variable gain adjustment for setting the X-axis display size. The EXT COUPLING switch provides for either direct (DC) or capacitive (AC) coupling of the external input signal. The external signal is coupled to a pre-amplifier, differentially amplified by the output amplifier, and applied to the CRT for horizontal deflection. Positioning and horizontal gain controls also function with external input signals.
4-15. CIRCUIT DETAILS.
4-16. INPUT AC j)OWER. Input line power is supplied by a detachable three conductor power cord. This cord has a standard plug for wall outlet connection providing an electrical ground. Both sides of the line power are filtered immediately at the power input connector.
4-17. The line power transformer has two primary windings. SELECTOR switch A4S1 connects these windings in parallel for 115 V operation and in series for 230 V operation. When set for use 'with a 115 V source of line power, fuse A4F1 protects against excessive input current. When operated on 230 V line power, fuse A4F2 is also placed in the primary power circuit. With the front panel LINE toggle switch, A2Sl, in the

4-18. OW-VOLTAGE POWER SUPPLY. The lowvoltag power supply produces four regulated voltages for us throughout the oscilloscope and the plug-ins: +100 ,-100 V, +15 V and -12.6 V. Each supply is refere ced to the +100 V supply for regulation purpos s with the +100 V supply referenced to a 9volt te perature-compensated zener diode A1A2VR2. The + 00 V and -100 V supplies are also foldback curren limited, providing short-circuit protection.

+100 volts. Series regulator A1Q1 controls load current in order to maintain the output voltage at +100 V. Variations in output voltage due to changes in load or input line voltage are sensed by differential comparator A1A2Q3 and Q4. If the output of the +100 V supply changes, the full amount of the voltage change is applied to A1A2Q3 by A1A2VR2 while A1A2Q4 senses only a small part of the change in output voltage. The +100 V adjustment potentiometer A1A2Rll set the operating point of A1A2Q4. The

simplified block diagram of a typical lowpower supply is shown in figure 4-2. Unre ated alternating power is supplied by the

output voltage caused by input voltage variation or loa changes are detected by the voltage sensor. Comp ed against a voltage reference, changes in output voltage are detected and applied as feedback to the ver, which controls the series regulator. The series regulator acts as a variable resistance and operat s to increase its series resistance if the output voltag is high or decreases resistance when the output vo tage is low. The action of the series regulator is to aintain output voltage at a constant level.

+100 V supply operation. All current furnished by the supply flows through A1A2R4. As the current requirements increase to the limit of the supply capability, the voltage drop across A1A2R4 causes A1A2Q2 to conduct. Since the collector of A1A2Q2 and the output of differential comparator A1A2Q3/Q4 are coupled to drive A1A2Q1, the amount of current flowing as well as voltage variations control the operation of series regulator A1Q1.

4-20. urrent sensing takes place simultaneously with oltage sensing. If the load current increases above a certain level, the current sensor detects the increa e as a voltage drop across the series resistor. This i creased voltage drop causes the driver to bias the se ies regulator off.
4-21. he +100 V supply is used throughout the

4-24. Resistors A1A2R2 and A1A2R3 are used in conjunction with A1A2R4 for current foldback operation. When current exceeds capability in a current foldback circuit, the output voltage will begin to drop and the load will receive less current. If the output of the supply is short-circuited, the output current will be limited to considerably less than the current available at full loading.

These three signals may be present singly or simultaneously, depending on control settings and signals applied.

Changes in output voltage are se sed by differential comparator A1A2Qll and A1A2 12 and coupled to driver A1A2Q9 which controls t e conduction of series regulator A1Q3. Current limitin action is provided by A1A2R22 and A1A2QlO.

4-36. The gate amplifier output unblanking signal is added to the -3200 V output of the high voltage power supply and applied to the CRT control grid. Voltage level changes of the unblanking signal cause corresponding changes to the CRT control grid voltage. Diodes A7CR6 through A7CR9 provide isolation protection against high voltage transients from the CRT control grid.

Fuse 1F3 protects against damage due to regulator failure and A1A2CR5 is used for voltage transient protec on.

Transistor A1A2Q14 with A1A2 3 provides current limiting. Current foldback operati n reduces the current output in the event of a sho ircuited load. Voltage and current variations

4-37. An alternate trigger signal is used by multichannel vertical amplifier plug-ins to initiate channel switching action. Transistors A7Q2 and A7Q3 function as a fast-acting switch. With A7Q2 normally conducting and A7Q3 non-conducting, the unblanking gate trailing edge causes A7Q3 to conduct and A7Q2 to cease conducting. The switching output is differentiated and applied to A7Q4, providing a negative. going voltage pulse for vertical amplifier channel switching.

are co pled to driver A1A2Q13 which controls the condu ion of series regulator A1Q4. Adjustment of the su ply output voltage is accomplished with potentiomet A1A2R40. Turn-on/turn-off protection is furnis ed by A1A2CR6, while A1A2CR7 provides reverse voltage protection for C9.

4-38. The input impedance to the Z-axis input is approximately 5100 ohms. An input signal of approximately +2 volts amplitude is sufficient to blank a trace of normal viewing intensity, while an input signal of -2 volts will provide unblanking. Since the gate amplifier has a voltage gain of about 10, a 2-volt input will result in a 20-volt change at the CRT grid.

4-32. ATE AMPLIFIER. The inputs to the gate am-

plifie are an unblanking gate, a chopped blanking signal, or an externally applied input Z-axis signal.

applied to the cathode (-3150 V), control grid (-3200 and post-accelerator (+19 kV) of the CRT to provi e the accelerating potential required to produce xcitation of the CRT phosphor for a visible trace. Th HVPS is shown in simplified from in figure 4-3. Ref to this figure, and to the schematic in Section III while reading the following explanation of HVPS operation.
4-40. Chassis-mounted transistor Q1 and transformer A6A1T1 form an oscillator that generates approximately 3 V POp at 40 kHz. A feedback winding on the transfo er provides the regenerative coupling to sustain 0 cillation. Operating power is provided by the unregula ed +27 V supply. The supply source is fused and deco pled.
4-41. Th 40-kHz oscillator output is stepped up by the seco dary windings of A6Tl. Two half-wave rectifiers and a voltage multiplier are used to develop the high oltages necessary for CRT operation.
4-42. Th CRT grid voltage is developed by half-wave rectifier 6CR1 and filter A6C1, A6C2, and A6R1 through 6RS. The display intensity lower limit, determined b the CRT grid voltage level, is adjusted by A6R2. e CRT cathode voltage and the focusing voltage, app oximately -2270 V, are developed by halfwave r . er A6CR4 and filter A6C3, A6C4, and A6R7. A R8 is part of a voltage divider that drops the -31 0 V to -2270 V for focus control. Diodes A6CRS nd A6CR6 prevent the CRT grid from becomin positive with respect to the cathode. The CRT pos -accelerator voltage is developed by highvoltage ultiplier assembly AIL
4-43. V .ations in high voltage output are fed back to the gh-voltage regulator circuitry consisting of AlOQ1, lOQ2, AlOQ3, and associated components. The regu ator controls the high voltage oscillator bias to maint in high voltage at a constant level. If, for example, t e CRT cathode voltage tends to decrease (go

more positive), a positive-going signal is applied through the regulator to the base of oscillator Ql. The oscillator then conducts for a greater period of time, causing a larger voltage change at the primary of A6T1. This increases the secondary voltage to restore cathode voltage to the desired level.
4-44. The high-voltage regulator monitors CRT cathode voltage through coupling network A6R9 and A6C5. Resistors AlOR3 and AlOR4 form a voltage divider between +100 V and the coupling network output. A10R3 adjusts the operating level of FET AlOQl. High voltage fluctuations are sensed by A1OQ1 and amplified by A10Q2 and AlOQ3. Diodes A10CR4 and AlOCRS provide clamping action to prevent overdriving the high-voltage oscillator. The regulator output is applied through the regenerative winding of A6T1 as bias to the base of Q1, thereby controlling high-voltage oscillator drive.
4-45. CALIBRATOR. The calibrator provides outputs of 10 volts and 250 millivolts at approximately I-kHz. The calibrator output is a negative-going waveform.
4-46. Transistors A2Q1 and A2Q2 oscillate at a rate determined by the time constant of associated RC components. A2CR1 disconnects the collector of A2Q2 from the negative discharge of A2C3 and A2Q2 cuts off, resulting in a faster rise time. Diodes A2CR2 and A2CR3 protect the transistors from voltage breakdown. A filter network, A2L1 and A2C4, isolates the multivibrator from the -100 V supply.
4-47. With A2Q2 conducting, voltage divider A2R17, A2R18, and A2R19 divides the -100 V supply voltage. The values selected for these resistors permit the output of 10 V and 250 mY. These two outputs are available at the front panel and may be used for probe compensation adjustment and horizontal or vertical sensitivity calibration checks.

e Adjust vertical plug-in volts/div and vernier contr Is to obtain an 8-div. display.
f. Observe displayed waveform. At this stage of adju ment waveform will typically exhibit 5% (approxi ately 0.5 div) overshoot. If overshoot is greater, adjus HF Adj No.1 A5C21, HF Adj No.2 A5C24, and F Adj No.3 A5C28 to obtain flat-top response with pproximately 5% overshoot on lower right-hand corne of displayed pulse.
NOTE
Capacitors for HF Adj No.1 and HF Adj No.3 should be adjusted so their slugs are almost equally extended.
5-40. HORIZONTAL LINEARITY. This adjustment is appli able only when using group A plug-ins at fast swee speeds. Before proceeding with this adjustment chec linearity and if magnified sweep timing is within speci cations do not perform this adjustment. To perfo m horizontal linearity check proceed as follows:
NOTE
Ensure that time base has been properly calibrated before proceeding with this adjustment.

a. Set HORIZONTAL DISPLAY to INT.
b. Connect 4 V pop, 50-MHz sine-wave output from time-mark generator to vertical input.
c. Set HORIZOl'fTAL MAGNIFIER TO X10.
d. Select fastest sweep speed (.05 or .1 !-Ls/div) and obtain display.
e. Adjust HF Adj No.1, A5C20, No.2, A5C24:, and No.3, A5C28, for best overall linearity of center 80 divisions of available display. Use HORIZONTAL POSITION control to permit viewing right, center', and left portions of display. HF Adj No.1 affects right portion, HF Adj No.2, center portion, and Hl~ Adj No.3, left portion of sweep.
f. Disconnect time-mark generator.
5-41. Tnis completes the adjustment procedure. If desired, the instrument performance may be tested to specifications using the Performance Check procedure. If satisfactory adjustment or instrument performance is not obtained refer to Section VIII of this manual for trouble-shooting information.

SECTION VIII SCHEMATICS AND TROUBLESHOOTING

8-1. INTRODUCTION.
8-2. This section contains schematics, repair and replacement information, component identification illustrations, and troubleshooting and repair information. Table 8-1 defines symbols and conventions used on the schematics. The overall block diagram is located in Section IV.
8-3. SCHEMATICS.
8-4. The schematics are drawn to show the electronic function of the circuit and instrument. A given schematic may include all or part of several assemblies. Schematics also include dc voltages and waveforms. Information explaining the symbols and conventions used in these schematics is in table 8-1. Voltage measurement conditions applicable to each schematic are shown next to the schematic.
8-5. Each schematic is identified by a number. The number of the schematic is located in the lower right hand corner near the figure number and title. These numbers are used to cross reference signal connections that begin on one schematic and continue on another. When a circuit leaves a schematic it is identified with the number of the schematic on which it is continued. Both schematics have the same circuit identification information such as voltage, function or circuit connection.
8-6. REFERENCE DESIGNATIONS.
8-7. The unit system of reference designations used in this manual is in accordance with provisions of the ANSI Standard Reference Designations for Electrical and Electronic Parts and Equipments dated March I, 1968. Minor variations due to design and manufacturing practices not specifically covered by the standard may be noted.
8-8. Each electrical component is identified by a class letter and number. This letter-number combination is the basic reference designation for each component. Components that are separately replaceable and are part of an assembly have, in addition to the basic designation, a prefix designation indicating . the assembly on which the component is physically located. Components not located on an assembly will have only the basic designation and are listed in the replaceable parts list (Section VI) under chassis parts.

8-9. All components located on an etched circuit board should be prefixed with the assembly number assigned to the board (e.g. resistor R23 on assembly A3 is referred to as A3R23). There may also be an . R23 on several other assemblies, but the assembly designation will always be different (A2R23, AIR23, etc.).
8-10. COMPONENT LOCATION.
8-ll. All adjustments are shown in Section V, and mechanical and miscellaneous electrical parts are shown on exploded view drawings in Section VI. For ready reference, circuit assembly photographs are placed adjacent to the associated schematics.
8-12. Circuit assembly photographs are subdivided by a grid, and components within each subdivision are indexed to a location table below the photograph. A component can be located on the photograph by first referring to the table. However, reference designations are not complete on the assembly photographs. For the complete reference designation, prefix the assembly designation given in the photograph to each component designation.
8-13. TROUBLESHOOTING.
8-14. The most important prerequisite for successful troubleshooting in understanding how the instrument operates and correct usage of controls.
8-15. Improper control settings can cause apparent malfunctions. Refer to the operating instructions in Section III for a complete explanation of each control's function along with typical operating instructions if in doubt. Use the controls as a guide to help isolate a trouble to a specific area of the instrument.
8-16. Troubleshooting is easier if more than one symptom of a trouble is evident. Observe the instrument, and note all indications of faulty operation. If symptoms indicate more than one trouble, treat each problem individually and locate one trouble at a time. Follow the procedure presented here, and refer to other areas of information in this manual if necessary.
8-17. Make a thorough check of instrument performance. A complete procedure is given in Section V, and forms are included to record results. A trouble, such as incorrect vertical gain or sweep speed, may be due to lack of calibration.
"18. PRELIMINARY CHECKOUT. To help isolate malfunctions, perform the following checkout procedure:

a. Check for improper control settings (refer to Section III).
b. Check for proper operation of accessory equipment.
c. Visually inspect instrument for loose wire and cable connections. Check wiring to all board assemblies for proper connections.
d. Visually inspect for burned, broken, or chafed wires; charred or discolored components; and any other indication of physical damage.
e. Check for proper power supply voltages and determine that fuses are not open.
8-19. DETAILED CHECKOUT. If the trouble cannot be located using the preliminary checkout procedures, a detailed check of the circuits will be necessary. Troubleshooting charts, waveforms, and voltages are provided to help in locating problem areas and components. The troubleshooting charts and waveforms are to be used to isolate the problem to a specific area. The voltages can then be used to locate the faulty component within the problem area.
When taking waveform or dc voltage measurements, use extreme care to avoid shorting supply voltages or components.
8·20. De voltages are shown on the schematics near active components such as transistors. Waveforms are also placed on the schematics at points which will assist in determining proper circuit operation. As an aid to locating measurement points, a small dot is etched on the circuit board next to the emitter lead of each transistor, the source lead of FET's, the cathode end of diodes, and the positive end of electrolytic capacitors. Use these points to assist in voltage and resistance measurement tests and as guidance in properly replacing components.
8-21. TROUBLESHOOTING TABLES. Troubleshooting tips are given in several tables. Before doing the checks, be sure that the symptom is valid by checking control settings. For example, what may at first appear as no display may really be a no sweep problem.
8·22. REPAIR AND REPLACEMENT. The following paragraphs contain recommended procedures for repair and replacement of defective components. A complete list of components, with Hewlett-Packard part numbers and ordering information, is in Section VI. Contact the nearest HP Sales/Service Office listed at the rear of this manual if satisfactory repair or operation cannot be achieved.
8-23. SERVICING ETCHED CIRCUIT BOARDS. Etched circuit boards in this instrument have components

mounted on one side of the board, conductive surfaces on both sides, and plated-through component mounting holes. Hewlett-Packard Service Note M·20E contains useful information on servicing etched circuit boards. Some important considerations are as follows:
a. Use a 37 to 47.5 watt chisel tip soldering iron with a tip diameter of 1/16 to 1/8 inch, and a small diameter rosin core solder.
b. Components may be removed by placing the soldering iron on the component leads on either side of the board and pulling the component straight away from the board. If heat is applied to the component side of the board, greater care is required to avoid damage to the components, especially semiconductors. Heat damage may be minimized by gripping the lead with long-nosed pliers between the soldering iron and the component, thereby forming a heat sink.
c. If a component is obviously damaged or faulty, clip the leads close to the component and then unsolder the leads from the board.
d. Large components, such as potentiometers, may be removed by rotating the soldering iron from lead to lead and applying steady pressure to lift the part free. The alternative is to clip the leads of the damaged part and remove them individually.
e. Excessive heat or force will destroy the laminate bond between the metal plated surface (conductor) and the board. If this problem should occur, the lifted conductor may be cemented down with a small amount of quick-drying acetate-base cement having good insulating properties. Another method of repair is to solder a section of good conducting wire along the damaged area.
f. Before replacing a component, heat the remaining solder in the component hole and clean it out with a desoldering tool. Sharp pointed metallic tools are not recommended since they may loosen eyelets in boards or remove plating from the inside of holes on plated-through etched circuit boards.
g. Tin and shape replacemnt component leads to fit existing holes.
h. Install the replacement component in the same position as the original.
8-24. SEMICONDUCTOR REPLACEMENT. Semiconductor devices are available in a wide variety of shapes and sizes. This can make it confusing to identify the leads. Examples of some of the most common configurations are shown in figure 8·1.
8-25. When removing a semiconductor, use a pair of long-nosed pliers as a heat sink between the device and the soldering iron. And, when replacing a semiconductor, ensure sufficient lead length to dissipate

;8-32. HIGH-VOLTAGE POWER SUPPLY AND REGULATOR.

8-26. DETAILED TROUBLESHOOTING.

I WARNING'

8·27. The following troubleshooting tips are categorized according to the various areas of the instrument. These tips can be helpful only after a trouble is localized to one of these areas. Read the theory of operation in Section IV to learn how a circuit should operate. If it appears necessary to calibrate the instrument, refer to Section V for the proper procedures.
8-28. LOW·VOLTAGE POWER SUPPLY. Fuses, test points for measuring regulated output voltages, and voltage adjustment controls are located on the lowvoltage regulator assembly. Access to the assembly is obtained by removing the instrument rear panel. Each low-voltage supply is fused. The fuses are in series with the regulator transistors, and all regulated output power flows through the fuse for the respective supply.
8-29. Since the +100 V and -100 V supplies are current fold-back limited, and the +15 V and -12.6 V supplies are current limited, an open fuse generally indicates that trouble exists in the regulator portion of the supply. If a fuse is open, check the series regulator transistor, driver transistor, and comparator.
8·30. Troubleshooting the low-voltage supply is facilitated by removing the power supply from the oscilloscope. This will provide access to the power transformer, rectifiers, and filters. Removing the module also disconnects the power supply from all other circuits of the oscilloscope, thus confining the troubleshooting effort to the low-voltage supply. The procedure for removing the power supply module is explained later in this section of the manual.
I I WARNING

Lethal voltages are exposed when the oscilloscope is turned on with the highvoltage power supply cover removed. High-voltage power supply problems are usually indicated by no display, a display that is too bright, an arcing sound, slow trace shift or blooming, or sudden shifts in display intensity. Regulator problems may result in no high voltage or excessive high voltage.
8-33. If only one high-voltage output is missing, check the appropriate rectifier and filter circuit. If high voltage is present but not properly adjusted, refer to the high-voltage troubleshooting tables.
I I WARNING
The CRT post-accelerator lead may have a high voltage present even if the instrument has been turned off for a long time. Ground both CRT and H.V. Multiplier connections to discharge them.
8-34. If no high voltage is present, check the highvoltage oscillator circuitry. The oscillator supply voltage, unregulated +27 V, is fused by F3 on the regulator assembly. The oscillator frequency is approximately 40 kHz. With the High Voltage Multiplier output disconnected, (by disconnecting the CRT postaccelerator lead) the oscillator frequency should increase to approximately 50 kHz.
8-35. The CRT cathode and grid high-voltage leads can be disconnected by removing the CRT socket. This will further isolate the trouble. If it is determined that the H.V. Multiplier is faulty, it must be replaced as a complete unit, since it is a sealed assembly.
8-36. DISASSEMBLY INFORMATION.

Lethal voltages are exposed when the power supply module is operated outside the oscilloscope mainframe.
8-31. The +100 V supply should be checked first, since all other supplies use it as a reference. Unregulated operation of all of the other supplies may be the result of a defective +100 V supply. Use the test points to monitor the regulated output of a supply. If the +100 V supply is defective, verify operation of the reference supply which is regulated by the 9-volt zener diode.

8·37. COVER REMOVAL. The instrument has a twopiece cover. Remove the covers as follows:
a. Ensure that LINE power switch is OFF and disconnect power plug from line power source.
b. Release the three-quarter-turn fasteners located on each side of the instrument. The cover retainers will be completely free. Figure 8-2 shows the location ofthe fasteners.
c. Loosen two captive screws located on handle ends.
d. Remove top cover by expanding slightly and pulling away from instrument.

Figure 8-2. Cover Removal

e. Remove bottom cover by extending tilt stand, expanding and pulling away from instrument.
f. Remove rear access cover by releasing singlequarter-tum fastener.
8-38. POWER MODULE REMOVAL. The low-voltage power module includes the power transformer, lowvoltage rectifier assembly, low-voltage regulator assembly, and the series regulators. The entire module is removable as a unit which can be further disassembled if desired.
8-39. To remove the power module, disconnect ac power input, remove the covers and proceed as follows:
a. Remove four screws located on bottom rear of instrument.
b. Return instruments to horizontal position and remove two rear screws. One screw is located on top of each series regulator heat sink. Do not remove screws holding rear feet to heat sink or screws located below rear feet.
c. Disconnect CRT filament lead connectors (brown wires) from rectifier assembly using longnosed pliers and lifting straight up. (CRT filament leads may also be disconnected later, refer to step d.)
I I WARNING
Filament leads operate at -3150 volts when power is on.

Model 182T
d. Remove module by grasping filter capacitors on each side and pressing toward rear of instrument. If CRT filament leads were not previously disconnected, be careful to pull module only partially free. Then disconnect filament leads and remove module.
8-40. CONTROL ASSEMBLY REMOVAL. This assembly includes the calibrator, CRT controls, and LINE power switch. To remove the controls assembly, disconnect ac power input, remove the covers, and proceed as follows:
a. Disconnect five square-pin connections between cable located on the underside of the assembly and the Interconnect assembly circuit board.
b. Disconnect eight square-pin connections located on the top side of the assembly. Use a longnosed pliers and pull connections straight off to remove. These consist of: CRT focus (two right-angle connections), trace alignment (two connections), CRT flood-gun (two connections), CRT mesh, (one connection), and ground (one connection).
c. Remove four screws from underside of control assembly. Two screws hold the assembly to the front casting frame and also hold the focus high-voltage shield in place. The other two screws are located approximately at the center of the assembly.
d. Grasp the assembly internal to the instrument and remove with a straight pull toward the front of the instrument. Do not remove by pulling on knobs. Be careful that square-pins located on top of the assembly do not catch on front casting frame.
8-41. AC POWER INPUT MODULE REMOVAL. The power input module contains the. line power jack, line filter, fuse holders, and UNE SELECTOR switch. It may be partially removed for servicing or completely removed ~: necessary.
8-42. Partial removal is possible since the cable carrying ac line power is long enough to expose the components without disconnecting the cable. To release the module, disconnect ac power input and remove the two screws holding the panel in place. Pull the module to the rear of the instrument.
8-43. If complete removal is desired, either remove the low-voltage power module or open the upper rear panel. This exposes the ac line power cable connections to the Interconnect assembly. Then disconnect six square-pin connections from the cable to the Interconnect assembly circuit board. The module can now be completely removed from the oscilloscope.
8-44. SWEEP-GATE ASSEMBLY REMOVAL. The Sweep-gate amplifier is located on the upper rear panel of the instrument. It is exposed for servicing by removing four screws holding the rear panel to the rear casting frame. (Do not remove rear feet from panel.) If complete removal is desired, disconnect 12 square-pin connections to the assembly. Five BNC
