SOURce Subsystem

The SOURce subsystem controls the signal characteristics of

the tracking generator. Refer also to the “OUTPut

Subsystem” on page 89 which contains a command that

controls the tracking generator output.

Sets the Output Power Offset Correction

:SOURce:CORRection:OFFSet <rel_ampl>

:SOURce:CORRection:OFFSet?

Specifies an offset for the displayed output power level. An

offset power level can be added to the displayed level to

compensate for system losses (for example, cable loss) or

gains (for example, preamplifier gain.) This offset does not

change the power out of the source, it only changes the

display so that it reads out the actual power delivered to the

device under test.
