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.
