The power level offset (in dB) from the PNA test port power. Calibration power is the sum of the test port power setting and PowerLevelOffset value.

The default value is 0.0

Calibrations of the following type use this value:

The power level offset magnitude is a gain or loss value (in dB) to account for components you connect between the source and the reference plane of your measurement. For example, specify 10 dB to account for a 10 dB amplifier at the input of your DUT. Due to the limitations of the PNA be aware that a PowerLevel value will not be applied when doing a source Power calibration. For source Power calibrations the test port power must be set in advance on the PNA before the power calibration is run. This can be achieved using a CSA file (see the key LoadFilename).

This key corresponds with the PNA SCPI command "SOURce<ch>:POWer<port>:CORRection:OFFSet[:MAGNitude] <num>[,src]" parameter as explained the Keysight Documentation
