Programming a Channel Power Measurement

This section provides an example of how to make a channel 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.
For information on configuring the test set for a call, see
The basic procedure to measure digital average power is as follows:
1. Make a call.
2. Configure the digital average power setup parameters using the
3. Use open and/or closed loop power control to set the mobile station power level.
4. Start the channel power measurement using the
5. Use the "FETCh:CPOWer"
