LTE Frequency Error Verification (Option 542)
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.
