The power level offset (in dB) of the IM Spectrum Calibration second source. Source power is the sum of the source port power level and SourceLevelOffset value

The second source is specified using the SourceIndex.

Calibrations of the following type are required to set this value.

The 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.

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