AMPTD Y Scale
Max Mixer Level
Controls the limitation on the Ref Level for a given attenuation setting, and therefore also interacts with
the Auto rules for selecting the attenuation as a coupling from the reference level.
Range
This key is only available when I/Q is the selected input. It replaces the Attenuation key in that case.
Each input channel (I and Q) has four internal gain ranges. The maximum allowed voltage in each gain
range is slightly more than the nominal value, so the break point between ranges is a couple of millivolts
higher than the nominal (setting a peak voltage of 0.502 mV will still map to the 0.5 V Peak range).
