Basic Settings
In order to carry out broadband signal analysis, the YIG filter at the input of the
R&S FSQ can be removed from the signal path.
The YIG (ON OFF) softkey switches the YIG to the RF path by means of relays or
bypasses the filter. With bypassed YIG filters, the maximum bandwidth can be used
for signal analysis. However, image-frequency rejection is no longer ensured.
Remote command: INP:FILT:YIG ON|OFF
