YIG-Preselector
Activates or deactivates the YIG-preselector, if available on the R&S FSW.
An internal YIG-preselector at the input of the R&S FSW ensures that image frequen-
cies are rejected. However, this is only possible for a restricted bandwidth. To use the
maximum bandwidth for signal analysis you can deactivate the YIG-preselector at the
input of the R&S
FSW, which can lead to image-frequency display.
Note that the YIG-preselector is active only on frequencies greater than 8 GHz. There-
fore, switching the YIG-preselector on or off has no effect if the frequency is below that
value.
Remote command:
INPut:FILTer:YIG[:STATe]

FSW67 or R&S FSW85.
For more information on the Analog Baseband Interface (R&S FSW-B71), see the
