Mixer Lvl Offset
This is an advanced setting to adjust target Range at the input mixer, which in turn
affects the signal level in the instrument’s IF. This setting can be used when
additional optimization is needed after setting "Peak-to-Average Ratio" on page
1784. Positive values of offset optimize noise performance over distortion, negative
values optimize distortion performance over noise.

3.2.3.5 Signal Path
Contains controls that pertain to the routing of the signal through the frontend of
the instrument.
In general, only appears in instruments whose hardware supports this signal
routing. For example, this tab does not appear in many of the modular instrument
products, including VXT Model M9420A, or UXM.
