I have developed a lot of code for the 8722ET network analyser. I am evaluating an E8361A at the moment. A feature in the 8722ET that I use to compute an offline calibration was "RAW OFFSET OFF" (RAWOFFS ON/OFF) which turns off the sampler and attenuator offsets. It is no no longer a valid SCPI commands on the new instrument. Does anyone know the equivalent way to setup the E8361A instrument to the same state that is defined by this "RAW OFFSET OFF" option on the 8722ET?
