The EUT and transmitting antenna shall be centered on the turntable. Test Condition The EUT shall be tested 1 near top, 1 near middle, and 1 near bottom. Set the unlicensed wireless device to operate in continuous transmit mode. For unlicensedwireless devices unable to be configured for 100% duty cycle even in test mode, configure thesystem for the maximum duty cycle supported. When required for unlicensed wireless devices, measurements of the variation of the input power or theradiated signal level of the fundamental frequency component of the emission, as appropriate, shall beperformed with the supply voltage varied between 85% and 115% of the nominal rated supply voltage. Exploratory radiated emissions measurements Exploratory radiated measurements shall be performed at the measurement distance or at a closer distancethan that specified for compliance to determine the emission characteristics of the EUT and, if applicable,the EUT configuration that produces the maximum level of emissions. The frequencies of maximumemission may be determined by manually positioning the antenna close ©Copyright. All rights reserved by CTTL. Page 20 of 47. No.I22Z61676-IOT06 to the EUT, and then moving theantenna over all sides of the EUT while observing a spectral display. It is advantageous to have priorknowledge of the frequencies of emissions, although this may be determined from such a near-field scan.The near-field scan shall only be used to determine the frequency but not the amplitude of the emissions.Where exploratory measurements are not adequate to determine the worst-case operating modes and areused only to identify the frequencies of the highest emissions, additional preliminary tests can be required. For emissions from the EUT, the maximum level shall be determined by rotating the EUT and itsantenna through 0° to 360°. For each mode of operation required to be tested, the frequency spectrum(based on findings from exploratory measurements) shall be monitored. Broadband antennas and a spectrum analyzer or a radio-noise meter with a panoramic display are oftenuseful in this type of test. If either antenna height or EUT azimuth are not fully measured duringexploratory testing, then complete testing can be required at the OATS or semi-anechoic chamber when thefinal full spectrum testing is performed. Final radiated emissions measurements The final measurements are using the orientation andequipment arrangement of the EUT based on the measurement results found during the preliminary(exploratory) measurements, the EUT arrangement, appropriate modulation, and modes ofoperation that produce the emissions that have the highest amplitude relative to the limit shall be selectedfor the final measurement. For emissions from the EUT, the maximum level shall be determined by rotating the EUT and itsantenna through 0° to 360°. Final measurements for the EUT require a measurement antenna height scan of 1 m to 4 mand the antenna rotated to repeat themeasurements for both the horizontal and vertical antenna polarizations. For each mode of operation required to be tested, the frequency spectrum(based on findings from exploratory measurements) shall be monitored. For each mode selected, record the frequency and amplitude of thehighest fundamental emission (if applicable), as well as the frequency and amplitude of the six highestspurious emissions relative to the limit. Emissions more than 20 dB below the limit do not need to bereported. This maximization process was repeated with the EUT positioned in each of its three orthogonal orientations.

Exploratory radiated emissions measurements Exploratory radiated measurements shall be performed at the measurement distance or at a closer distancethan that specified for compliance to determine the emission characteristics of the EUT and, if applicable,the EUT configuration that produces the maximum level of emissions. The frequencies of maximumemission may be determined by manually positioning the antenna close to the EUT, and then moving theantenna over all sides of the EUT while observing a spectral display. It is advantageous to have priorknowledge of the frequencies of emissions, although this may be determined from such a near-field scan.The near-field scan shall only be used to determine the frequency but not the amplitude of the emissions.Where exploratory measurements are not adequate to determine the worst-case operating modes and areused only to identify the frequencies of the highest emissions, additional preliminary tests can be required. For emissions from the EUT, the maximum level shall be determined by rotating the EUT and itsantenna through 0° to 360°. For each mode of operation required to be tested, the frequency spectrum(based on findings from exploratory measurements) shall be monitored. Broadband antennas and a spectrum analyzer or a radio-noise meter with a panoramic display are oftenuseful in this type of test. If either antenna height or EUT azimuth are not fully measured duringexploratory testing, then complete testing can be required at the OATS or semi-anechoic chamber when thefinal full spectrum testing is performed. Final radiated emissions measurements The final measurements are using the orientation andequipment arrangement of the EUT based on the measurement results found during the preliminary(exploratory) measurements, the EUT arrangement, appropriate modulation, and modes ofoperation that produce the emissions that have the highest amplitude relative to the limit shall be selectedfor the final measurement. For each mode of operation required to be tested, the frequency spectrum(based on findings from exploratory measurements) shall be monitored. The highestsignal levels relative to the limit shall be determined by rotating the EUT from 0° to 360° and with varyingthe measurement antenna height between 1 m and 4 m in vertical and horizontal polarizations. For each mode selected, record the frequency and amplitude of thehighest fundamental emission (if applicable), as well as the frequency and amplitude of the six highestspurious emissions relative to the limit. Emissions more than 20 dB below the limit do not need to bereported. This maximization process was repeated with the EUT positioned in each of its three orthogonal orientations.

AC Powerline Conducted Emission Method of Measurement:See ANSI C63.10-clause 6.2 Setup: A stand-alone EUT shall be placed in the center along the back edge of the tabletop. For multiunit tabletopsystems, the EUT shall be centered laterally (left to right facing the tabletop) on the tabletop and its rearshall be flush with the rear of the table. Accessories that are part of an EUT system tested on a tabletop shall be placed in a test arrangement on oneor both sides of the host with a 10 cm separation between the nearest points of the cabinets.The rear of the host and accessories shall be flush with the back of the supporting tabletop unless thatwould not be typical of normal use. If more than two accessories are present, then an equipment testarrangement shall be chosen that maintains 10 cm spacing between cabinets unless the equipment isnormally located closer together. Exploratory ac power-line conducted emission measurements Exploratory measurements shall be used to identifythe frequency of the emission that has the highest amplitude relative to the limit by operating the EUT in arange of typical modes of operation, cable positions, and with a typical system equipment configuration andarrangement. For each mode of operation and for each ac power current-carrying conductor, cablemanipulation shall be performed within the range of likely configurations. For this measurement or seriesof measurements, the frequency spectrum of interest shall be monitored looking for the emission that hasthe highest amplitude relative to the limit. Once that emission is found for each current-carrying conductorof each power cord associated with the EUT (but not the cords associated with non-EUT equipment in theoverall system), the one configuration and arrangement and mode of operation that produces the emissionclosest to the limit over all of the measured conductors shall be ©Copyright.

Final ac power-line conducted emission measurements Based on the exploratory tests of the EUT, the one EUT cable configuration andarrangement and mode of operation that produced the emission with the highest amplitude relative to thelimit is selected for the final measurement, while applying the appropriate modulating signal to the EUT. If the EUT is relocated from an exploratory test site to a final test site, the highest emissions shall be remaximized at the final test location before final ac power-line conducted emission measurements areperformed. The final test on all current-carrying conductors of all of the power cords to the equipment thatcomprises the EUT (but not the cords associated with other non-EUT equipment in the system) is thenperformed for the full frequency range for which the EUT is being tested for compliance without furthervariation of the EUT arrangement, cable positions, or EUT mode of operation. If the EUT is composed ofequipment units that have their own separate ac power connections (e.g., floor-standing equipment withindependent power cords for each shelf that are able to connect directly to the ac power network), then eachcurrent-carrying conductor of one unit is measured while the other units are connected to a second (ormore) LISN(s). All units shall be measured separately. If a power strip is provided by the manufacturer, tosupply all of the units making up the EUT, only the conductors in the power cord of the power strip shall bemeasured.
