Power Loss Correction List

If a directional coupler or power splitter is used to sample the RF power output of the analyzer, the RF signal going to the power meter may be different than that going to the test device. A directional coupler will attenuate the RF signal by its specified coupling factor. The difference in attenuation between the through arm and the coupled arm (coupling factor) must be entered using the loss/sensor list menu. Non-linearities in either the directional coupler or power splitter can be corrected in the same way.

Power loss information is entered in much the same way as limit line parameters. Up to 12 segments may be entered, each with a different attenuation value. The entered data will not be lost if the instrument’s power is cycled.

Power Sensor Calibration Factor List

Two power sensor calibration data lists can be created in the analyzer. No single power sensor covers the entire frequency range of the analyzer, therefore the calibration data for two different power sensors must be available. The entered data will not be lost if the instrument’s power is cycled.
