5-8 LTE Signal Analyzer Verification, Option 541 and 542
LTE Channel Power Accuracy Verification (Option 541)
The tests in this section verify the function of the optional LTE Signal Analyzer in Model S412E LMR Master.
Procedure
1. Connect the MA2482D Power Sensor to the power meter and zero the sensor.
2. Set the Power Meter Measurement MODE to True RMS, set Averaging MODE to Moving, and set
Averaging NUMBER to 256.
3. Set the calibration factor frequency of the power sensor to 797 MHz.
4. Connect the equipment as shown in
The LTE pattern requires a Waveform Data license MX370108A that must be purchased.
Note
Both Set keys on the MG3700A perform the same function.
5. Set the MG3700A as follows:
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) soft key Return.
h. Press the Set key. The Select Package list box will appear. Again select LTE_DL_E-TM and then
the Set key.
i. Another file list will appear. 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 797 MHz.
m. Press the Level key, then enter 2 dBm.
n. Turn the output on.
6. Adjust the MG3700A level setting with the knob so that the power meter reads –10.0 dBm ± 0.5 dB.
7. Set the S412E to LTE Signal Analyzer mode and preset the unit.
8. Set the S412E as follows:
a. Press the Freq main menu key and set the Center Freq to 797 MHz.
b. Press the Measurements submenu key and select RF, then select Channel Spectrum.
9. Record the S412E Channel Power reading in the 797 MHz, –10 dBm row, Measured Channel Power
column of Table A-30, "Option 541, LTE Channel Power
10. Calculate the Channel Power Error by subtracting the S412E "Channel Power" reading from the power
meter reading in
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.
