5-102 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
a. Press the yellow Preset button (answer yes to the question).
b. Press the Set key. .
c. Press the (F1) soft key to select Load File to Memory.
d. Press the (F1) soft key again to select Select Package.
e. Using the Down Arrow key, step through the selection list until “LTE_DL_E-TM” is highlighted.
f. Press the Set key.
g. Press the F6 (Return) soft key.
h. Press the Set key. The Select Package list box appears. Again select LTE_DL_E-TM and then press
the Set key.
i. Another file list appears. Select (highlight) E-TM_1-1_10M.
j. Press the Set key.
k. Press the MOD On/Off key and verify that the LED is On. Confirm that the “playing” indicator is
displaying the moving pattern.
l. Press the Frequency key, then enter 750 MHz.
m. Press the Level key, then enter –3 dBm.
n. Turn the output On.
6. Adjust the MG3700A level setting with the knob so that the power meter reads –20.0 dBm ± 0.5 dB.
7. Set the MT821xE to LTE Signal Analyzer mode and preset the instrument.
8. Set the MT821xE as follows:
a. Press the Freq main menu key and set the Center Frequency to 750 MHz.
b. Press the Measurements main menu key and press
RF, then press Channel Spectrum.
9. Record the MT821xE Channel Power reading in the 750 MHz, –20 dBm row, Measured Channel
Power column of Table A-91, “Option 541, LTE Channel Power Accuracy” on page A-54.
10. Calculate the Channel Power Error by subtracting the MT821xE “Channel Power” reading from the power
meter reading in Step 6. Record the result in the 750 MHz, –20 dBm row, Error column of Table A-91.
11. Verify that the error is within specification.
12. Adjust the MG3700A level setting to approximately –33 dBm so that the power meter
reads –50.0 dBm ± 0.5 dB.
13. Record the MT821xE Channel Power reading in the 750 MHz, –50 dBm row, Measured Channel
Power column of Table A-91.
14. Calculate the Channel Power Error by subtracting the MT821xE “Channel Power” reading from the power
meter reading that was recorded in Step 13. Record the result in the 750 MHz, –50 dBm row, Error
column of Table A-91.
15. Verify that the error is within specification.
16. Set the calibration factor frequency of the power sensor to 2150 MHz.
17. Set the MG3700A frequency to 2150 MHz. Press the Set key.
18. Change the MT821xE center frequency to 2150 MHz.
19. Measure the Channel Power for –20 dBm and –50 dBm and then record the measured result in the
Measured Channel Power column and the calculated error in the Error column of Table A-91.
20. Verify that the error is within specification.
Note Both Set keys on the MG3700A perform the same function.
