Swap IQ
Activates or deactivates the inverted I/Q modulation.
On I and Q signals are interchanged.
Off Normal I/Q modulation.
Remote command:
[SENSe:]SWAPiq on page 200
Input Sample Rate
Defines the sample rate of the digital I/Q signal source. This sample rate must corre-
spond with the sample rate provided by the connected device, e.g. a generator.
Remote command:
INPut:DIQ:SRATe on page 178
Full Scale Level
The "Full Scale Level" defines the level that should correspond to an I/Q sample with
the magnitude "1".
The level is defined in Volts.
Remote command:
INPut:DIQ:RANGe[:UPPer] on page 178
Auto Level Time
Specifies the sweep time used for the automatic level measurements.
Remote command:
CONFigure:POWer:AUTO:SWEep:TIME on page 154
Ref Level
Specifies the reference level to use for measurements. If the reference level is modi-
fied, the signal level is updated accordingly (depending on the currently selected stand-
ard and measurement type). This field is only editable if the "Auto Lvl" is deactivated.
