RF Atten Manual/Mech Att Manual
Opens an edit dialog box to enter the attenuation, irrespective of the reference level. If
electronic attenuation is activated (option R&S FSV-B25 only; "El Atten Mode Auto"
softkey), this setting defines the mechanical attenuation.
The mechanical attenuation can be set in 10 dB steps.
The RF attenuation can be set in 5 dB steps (R&S FSV with option R&S FSV-B25 or
R&S FSVA: 1 dB steps). The range is specified in the data sheet. If the current refer-
ence level cannot be set for the set RF attenuation, the reference level is adjusted
accordingly.
This function is not available for input from the R&S Digital I/Q Interface (option
R&S FSV-B17).
The RF attenuation defines the level at the input mixer according to the formula:
