3-8 Option 883, TD-LTE Signal Analyzer Verification Chapter 3 — Options Verification
3-30 PN: 10580-00342 Rev. D MS2720T MM
TD-LTE Channel Power Accuracy Tests
The tests in this section verify the function of the optional TD-LTE Signal Analyzer in Model MS2720T.
Setup
Procedure
1. Connect the 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 750 MHz.
4. Connect the Power Sensor, 1870A splitter, 6 dB attenuators (quantity 2), as shown in Figure 3-10.
