Programming a Gated Power Measurement
Programming a Gated Power Measurement
This section provides an example of how to make a gated power measurement via GPIB.
The following program example assumes that the mobile station’s antenna output is connected to the RF
IN/OUT connector, and the mobile station has found service.
The basic procedure to measure gated power is as follows:
1. Make a call using IS-95 or IS-2000 system type with F1R1 (radio configuration 1) or F2R2 (radio
configuration 2). See “CALL[:CELL]:RCONfig” .
2. Select a loopback service option (SO2, SO9, or SO55) .
3. Select eighth rate data (see “CALL:TRAFfic:DRATe” ).
4. Configure the gated power measurement setup parameters using the “SETup:GPOWer” subsystem.
5. Start the waveform quality measurement using the “INITiate” subsystem.
6. Use the “FETCh:GPOWer” command to obtain gated power measurement results.
NOTE Gated power measurement display trace data is available using the “FETCh:GPOWer:TRACe?”
command.
