With a reference level offset ≠ 0, the value range of the reference level is modified by
the offset. You can set the offset with
DISPlay<1...2>[:WINDow]:
TRACe<1...2>:Y[:SCALe]:RLEVel:OFFSet
on page 320.
The numeric suffix at DISPlay and TRACe are irrelevant for this command.
Parameters:
<RefLevel> Sets the reference level; the unit depends on
UNIT<1...2>:
POWer
on page 323.
Range: Specified in the data sheet.
*RST: –20 dBm
Default unit: dBm
Example: DISP:TRAC:Y:RLEV –60dBm
Sets the reference level to -60 dBm.
DISPlay<1...2>[:WINDow]:TRACe<1...2>:Y[:SCALe]:RLEVel:OFFSet <RefLvlOffset>
This command defines a reference level offset.
The numeric suffix at DISPlay and TRACe are irrelevant for this command.
Parameters:
<RefLvlOffset> Sets the reference level offset.
Range:
-100 dB to 100 dB
*RST: 0 dB
Default unit: dB
Example: DISP:TRAC:Y:RLEV:OFFS –10dB
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>[:
WINDow]:TRACe<1...2>:Y:SPACing
on page 319. For a linear scale, you cannot
modify the reference position.
The numeric suffix at DISPlay and TRACe are irrelevant for this command.
Parameters:
<RefLvlPosition> Defines the reference position in %.
Range:
0 to 10
*RST: 10
Example: DISP:TRAC:Y:RPOS 5
Sets the reference position to the 5th grid line.
INPut:ATTenuation<1...2> <Attenuation>
This command defines the input attenuation.
