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
Enables or disables frequency coupling between the R&S FSW and the connected
generator.
If disabled, a fixed frequency is used by the generator.

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
* Numerator / Denominator] + Frequency Offset
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.
