Reference Level Offset
Adds an offset value to the displayed reference level. The reference level is the absolute amplitude
represented by the top graticule line on the display.

Example DISP:WIND:TRAC:Y:RLEV:OFFS 12.7
Sets the Ref Level Offset to 12.7 dB. The only valid suffix is dB. If no suffix is sent, dB will be
assumed.
Preset 0 dBm
State Saved Saved in instrument state
Min The range for Ref Lvl Offset is variable. It is limited to values that keep the reference level within
the range of –327.6 dB to 327.6 dB.
Max 327.6 dB
Backwards Compatibility
Notes 1. In pre-X-Series instruments, Ref Level Offset could not be adjusted by the knob or step keys.
That is no longer the case.
2. In ESA and PSA, Ref Level Offset was applied to the data as it was acquired; thus if the Offset
changed the new offset was not applied until new trace data was taken. In X-Series, the offset
is applied as the data is displayed/queried, so if you change the offset, it will change the data
immediately.
