Programming a Waveform Quality/Code Domain Measurement
Programming a Waveform Quality/Code Domain Measurement
This section provides an example of how to make a waveform quality 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 waveform quality is as follows:
1. Make a call.
2. Configure the waveform quality measurement setup parameters using the “SETup:WQUality” subsystem.
3. Start the waveform quality measurement using the “INITiate” subsystem.
4. Use the “FETCh:WQUality” command to obtain waveform quality measurement results.
5. Use the “FETCh:WQUality:CDPower:ICHannel[:ALL]?” or
“FETCh:WQUality:CDPower:QCHannel[:ALL]?” commands to obtain code domain power measurement
results.
