Grid Abs/Rel
Switches between absolute and relative scaling of the level axis (not available with
"Linear" range).
Not available for Carr Freq Drift, Init Carr Freq Tol, and Modulation Char measure-
ments.
"Abs" Absolute scaling: The labeling of the level lines refers to the absolute
value of the reference level. Absolute scaling is the default setting.
"Rel" Relative scaling: The upper line of the grid is always at 0 dB. The
scaling is in dB whereas the reference level is always in the set unit
(for details on unit settings see the "Unit" softkey).

Input 50 Ω/75 Ω
Uses 50 Ω or 75 Ω as reference impedance for the measured levels. Default setting is
50 Ω.
The setting 75 Ω should be selected if the 50 Ω input impedance is transformed to a
higher impedance using a 75 Ω adapter of the RAZ type (= 25 Ω in series to the input
impedance of the instrument). The correction value in this case is 1.76 dB = 10 log (75
Ω/50 Ω).
All levels specified in this Operating Manual refer to the default setting of the instru-
ment (50 Ω).
This function is not available for input from the R&S Digital I/Q Interface (option
R&S
FSV-B17).

3.6 Softkeys of the Bandwidth Menu (option R&S
FSV-K8)
The following section describes all softkeys available in the "Bandwidth" menu in Blue-
tooth mode (BW key). It is possible that your instrument configuration does not provide
all softkeys. If a softkey is only available with a special option, model or (measurement)
mode, this information is delivered in the corresponding softkey description.
