Procedure:
1.
Preset the R&S FSW.
2. Set the center frequency to 1.8 GHz.
3. Set the RBW to 100 kHz.
4.
Set the sweep time to 640
μ s.
5. Set the trigger source to "IF Power".
6.
Define a trigger offset of -50
μ s.
7. Select the "Time Domain Power" measurement function from the "Select Measure-
ment" dialog box.
8. In the Time Domain Power configuration dialog box, set all four results to "ON".
9. Set the "Limit State" to "ON".
10.
Define the left limit at 326
μ s and the right limit at 538 μ s.
This range corresponds to the useful part of the GSM burst.
The mean power of the useful part of the GSM burst is calculated to be -13 dBm.
