"DISP CTXT;CDMA:TX:POW:MEAS 'Chan Power'"
selects Channel Power measurements.
"DISP CTXT;MEAS:CDM:CHAN?"
queries the channel power measurement.
"DISP CTXT;MEAS:CDM:CHAN:CAL"
calibrates channel power measurements (connect the DUPLEX OUT and RF IN/
OUT ports before sending this command).
Operating Considerations for the Channel Power Measurement
The cross-calibration process is performed by connecting a cable between the
DUPLEX OUT port and the RF IN/OUT port, then selecting the
field. Refer to
Calibrate
Set chapter of the HP 8924C Application Guide. Channel power measurements
must be calibrated whenever any of the following conditions occur:
• Uncal annunciator is flashing
• 5 °C change in operating temperature
• Test Set power cycle
• Daily
The Average Power measurement, which is used during cross-calibration, is
automatically zeroed during the calibration procedure.
No special measurement triggers are required for Channel Power measurements.
