DISPlay<1...2>[:WINDow]:TRACe<1...2>:Y[:SCALe]:RPOSition <RefLvlPosition>
This command defines the position of the reference level on the display grid.
First, you have to set a logarithmic scale for the vertical axis with
DISPlay<1...2>[:

on page 293. For a linear scale, you cannot
modify the reference position.
The numeric suffix at DISPlay and TRACe are irrelevant for this command.

0 to 10
*RST: 10
Example:
DISP:TRAC:Y:RPOS 5

INPut:ATTenuation <Attenuation>
This command defines the input attenuation.
The attenuation is coupled to the reference level. If you set the attenuation independ-
ently, the R&S Spectrum Rider turns off this coupling.
The R&S Spectrum Rider adjusts the reference level if it cannot be set for the current
RF attenuation.
Parameters:
<Attenuation> Range: 0 dB to 40 dB
*RST: 0 dB (AUTO is ON)
Default unit: dB
Example:
INP:ATT 30dB
Defines an attenuation of 30 dB and deactivates coupling to the
reference level.
