3 TEST CONDITIONS AND RESULTS
3.1 Output Power LIMIT

According to §90.635(b) specifies "The maximum output power of the transmitter for mobile stations is 100 watts(50dBm)."

TEST CONFIGURATION

Conducted Power Measurement

Radiated Power Measurement:
TEST PROCEDURE The EUT was setup according to EIA/TIA 603D Conducted Power Measurement: a) Place the EUT on a bench and set it in transmitting mode. b) Connect a low loss RF cable from the antenna port to a spectrum analyzer and CMW500 by a
Directional Couple. c) EUT Communicate with CMW500, then select a channel for testing. d) Add a correction factor to the display of spectrum, and then test. Radiated Power Measurement:
a. The EUT shall be placed at the specified height on a support, and in the position closest to normal use as declared by provider.
b. The test antenna shall be oriented initially for vertical polarization and shall be chosen to correspond to thefrequency of the transmitter
c. The output of the test antenna shall be connected to the measuring receiver. d. The transmitter shall be switched on and the measuring receiver shall be tuned to the frequency of the
transmitter under test. e. The test antenna shall be raised and lowered through the specified range of height until a maximum signal
level is detected by the measuring receiver.

Report No.: CTA24052101814

Page 9 of 21

f. The transmitter shall then be rotated through 360°in the horizontal plane, until the maximum signal level
is detected by the measuring receiver. g. The test antenna shall be raised and lowered again through the specified range of height until a maximum
signal level is detected by the measuring receiver. h. The maximum signal level detected by the measuring receiver shall be noted. i. The transmitter shall be replaced by a substitution antenna. j. The substitution antenna shall be orientated for vertical polarization and the length of the substitution
antenna shall be adjusted to correspond to the frequency of the transmitter. k. The substitution antenna shall be connected to a calibrated signal generator. l. If necessary, the input attenuator setting of the measuring receiver shall be adjusted in order to increase
the sensitivity of the measuring receiver. m. The test antenna shall be raised and lowered through the specified range of height to ensure that the
maximum signal is received. n. The input signal to the substitution antenna shall be adjusted to the level that produces a level detected by
the measuring receiver, that is equal to the level noted while the transmitter radiated power was measured, corrected for the change of input attenuator setting of the measuring receiver. o. The measurement shall be repeated with the test antenna and the substitution antenna orientated for horizontal polarization. p. The measure of the effective radiated power is the larger of the two levels recorded at the input to the substitution antenna, corrected for gain of the substitution antenna if necessary. q. Test site anechoic chamber refer to ANSI C63.4.

3.5 Spurious Emission
LIMIT
According to Part §90.691 specify that the power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10 log (P) dB. The specification that emissions shall be attenuated below the transmitter power (P) by at least 43 + 10 log (P) dB, translates in the relevant power range (1 to 0.001 W) to -13 dBm. At 1 W the specified minimum attenuation becomes 43 dB and relative to a 30 dBm (1 W) carrier becomes a limit of -13 dBm. At 0.001 W (0 dBm) the minimum attenuation is 13 dB, which again yields a limit of -13 dBm. In this way a translation of the specification from relative to absolute terms is carried out.

3.6 Frequency Stability under Temperature & Voltage Variations LIMIT
According to §90.213, §2.1055 requirement, the frequency stability shall be sufficient to ensure that the fundamental emissions stay within the authorized bands of operation and should not exceed 2.5ppm.
TEST CONFIGURATION

TEST PROCEDURE
The EUT was setup according to EIA/TIA 603D
Frequency Stability Under Temperature Variations: In order to measure the carrier frequency under the condition of AFC lock, it is necessary to make measurements with the EUT in a "call mode". This is accomplished with the use of R&S CMW500 DIGITAL RADIO COMMUNICATION TESTER. 1. Measure the carrier frequency at room temperature. 2. Subject the EUT to overnight soak at -30. 3. With the EUT, powered via nominal voltage, connected to the CMW500 and in a simulated call on middle channel for LTE band 26, measure the carrier frequency. These measurements should be made within 2 minutes of Powering up the EUT, to prevent significant self-warming. 4. Repeat the above measurements at 10 increments from -30 to +50. Allow at least 1.5 hours at each temperature, unpowered, before making measurements. 5. Re-measure carrier frequency at room temperature with nominal voltage. Vary supply voltage from minimum voltage to maximum voltage, in 0.1Volt increments re-measuring carrier frequency at each voltage. Pause at nominal voltage for 1.5 hours unpowered, to allow any self-heating to stabilize, before continuing. 6. Subject the EUT to overnight soak at +50. 7. With the EUT, powered via nominal voltage, connected to the CMW500 and in a simulated call on the centre channel, measure the carrier frequency. These measurements should be made within 2 minutes of Powering up the EUT, to prevent significant self-warming. 8. Repeat the above measurements at 10  increments from +50 to -30. Allow at least 1.5 hours at each temperature, unpowered, before making measurements 9. At all temperature levels hold the temperature to +/- 0.5 during the measurement procedure. Frequency Stability Under Voltage Variations:

Report No.: CTA24052101814

Page 20 of 21

Set chamber temperature to 20. Use a variable AC power supply / DC power source to power the
EUT and set the voltage to rated voltage. Set the spectrum analyzer RBW low enough to obtain the desired frequency resolution and recorded the frequency. Reduce the input voltage to specify extreme voltage variation (±15%) and endpoint, record the maximum frequency change.
