Keysight E6680A - Mixer Lvl Offset; Range (Baseband Input Models)

3 IQ Analyzer (Basic) Mode
3.1 Complex Spectrum Measurement
Example
:POW:RANG:PAR 12 dB
Notes In some Modes, this parameter is read-only; meaning the value will appear on the control and query
via SCPI, but is not changeable. In such applications the control is grayed-out. Attempts to change the
value via SCPI are ignored, but no error message is generated
Dependencies Does not appear in Spectrum Analyzer Mode

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
314. Positive values of offset optimize noise performance over distortion, negative
values optimize distortion performance over noise.

Only available when Option BBA is present (I/Q Baseband Inputs), the current
measurement supports option BBA, and I/Q is the selected input. In these cases,
replaces the Attenuation tab.
