YIG-Preselector
Activates or deactivates the YIG-preselector, if available on the R&S FPS.
An internal YIG-preselector at the input of the R&S FPS ensures that image frequencies are rejected. However, this is only possible for a restricted bandwidth. In order to
use the maximum bandwidth for signal analysis you can deactivate the YIG-preselector
at the input of the R&S FPS, which may lead to image-frequency display.
Note that the YIG-preselector is active only on frequencies greater than 8 GHz. Therefore, switching the YIG-preselector on or off has no effect if the frequency is below that
value.
Note:
For the following measurements, the YIG-Preselector is off by default (if available).
● I/Q Analyzer (and thus in all applications in MSRA operating mode)
● GSM
● VSA

7.4 Amplitude
The amplitude is configured in the "Amplitude" dialog box. Amplitude settings are identical to the Signal and Spectrum Analyzer mode.
For background information on amplitude settings see the R&S FPS User Manual.
7.4.1 Amplitude Settings
Amplitude settings determine how the R&S FPS must process or display the expected
input power levels.
To configure the amplitude settings
Amplitude settings can be configured via the AMPT key or in the "Amplitude" dialog
box.
► To display the "Amplitude" dialog box, do one of the following:
●
●
Select "Input/Frontend" from the "Overview" and then switch to the "Amplitude"
tab.
Select the AMPT key and then the "Amplitude Config" softkey.
