Operating Considerations for the Channel Power Measurement

The cross-calibration process is performed by selecting the Power Meas, Calibrate field. Refer to “Calibrating the Test Set” in the Calibrating the Test Set chapter of the E8285A 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.
