Chapter 4, Description of Fields

Fields

Power Meas

This field provides Average Power zeroing (when Average Power is selected) and Channel Power calibration (when Channel Power is selected).

Calibrate

Refer to the Chan Power field description, on page 197.

Zero

Refer to the Avg Power field description, on page 178.

GPIB Example

“CDMA:TX:POW:MEAS ‘Chan Power’;:MEAS:CDM:CHAN:CAL“

selects and calibrates the Channel Power measurement.

“CDMA:TX:POW:MEAS ‘Avg Power’;:MEAS:CDM:AVGP:ZERO“

selects and calibrates the Average Power measurement.

Operating Considerations, Power Zero

The Power Zero field is displayed when Avg Power is selected in the Avg Power/Chan Power field. To zero Average Power measurements, select Power Zero. If the message “Zero degraded. Reduce generator level for best results" appears, reduce or use the Yes On/Off key to reduce RF Power, which is the sum of the Sector A, Sector B, and AWGN sources.

Operating Consideration, Calibrate

The Calibrate field is displayed when Chan Power is selected in the Avg Power/Chan Power field. To calibrate Channel Power measurements, connect the DUPLEX OUT connector to the RF IN/OUT connector and select Calibrate.

A flashing Uncal annunciator will be displayed below the Chan Power field when the Channel Power measurement has not been calibrated for the frequency band selected in the RF Chan Std field.
