stop or center frequency is reduced below 7 GHz, electronic attenuation is available
again. If the electronic attenuation was defined manually, it must be re-defined.
The attenuation can be varied in 1 dB steps from 0 to 30 dB. Other entries are rounded
to the next lower integer value.
To re-open the edit dialog box for manual value definition, select the "Man" mode
again.
If the defined reference level cannot be set for the given RF attenuation, the reference
level is adjusted accordingly and the warning "Limit reached" is output.

Ref Level Offset
Opens an edit dialog box to enter the arithmetic level offset. This offset is added to the
measured level irrespective of the selected unit. The scaling of the y-axis is changed
accordingly. The setting range is ±200 dB in 0.1 dB steps.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RLEVel:OFFSet

Ref Level Position
Opens an edit dialog box to enter the reference level position, i.e. the position of the
maximum AD converter value on the level axis. The setting range is from -200 to
+200
%, 0 % corresponding to the lower and 100 % to the upper limit of the diagram.
Only available for RF measurements.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RPOSition

Grid Abs/Rel
Switches between absolute and relative scaling of the level axis (not available with
"Linear" range).
Only available for RF measurements.
"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).
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:MODE

Input (AC/DC)
Toggles the RF input of the R&S FSVA/FSV between AC and DC coupling.
This function is not available for input from the R&S Digital I/Q Interface (option
R&S
FSV-B17).
Remote command:
INPut:COUPling
