Example Set the Ref Level Offset to 12.7dB. The only valid suffix is dB. If no suffix is sent, dB will be assumed:
:DISP:WIND:TRAC:Y:RLEV:OFFS 12.7
:DISP:WIND:TRAC:Y:RLEV:OFFS?
:DISP:WIND:TRAC:Y:RLEV:OFFS:STAT ON

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
Annotation The offset is displayed as “Ref Offset <value>” to the right of the reference level annotation if nonzero.
When the offset is zero, no annotation is shown
Ref Position
Positions the reference level at the top, center, or bottom of the Y Scale display.
Changing the reference position does not change "Ref Value" on page 1555.
