The overall status of the frequency coupling is indicated by an LED next to the fre-
quency definition.
The LED indicates the following states:
●
green:
frequency setting valid
●
red:
frequency value cannot be applied on the signal generator
●
gray:
signal generator control or coupling off
Generator Frequency Coupling State
......................................................................... 232
Generator Frequency Coupling State
Enables or disables frequency coupling between the R&S
FSW and the connected
generator.
If disabled, a fixed frequency is used by the generator.
Remote command:
CONFigure:GENerator:NPRatio:FREQuency:COUPling[:STATe]
f
Gen
Indicates the resulting frequency setting on the generator, depending on the other fre-
quency parameters.
The generator frequency is defined as:
f
Gen
= [f
Analyzer
*
Any changes to one of the interdependent parameters automatically affect the calcula-
ted signal levels on the connected generator.
If
Generator Frequency Coupling State
is disabled, define a fixed frequency to be used
by the generator.
