LEVEL
The following command is not available on the AQ6375/AQ6375B if the horizontal axis is
set to Wavenumber mode.
LEVEL UNIT ###### #####: dBm, dBm/nm
Program Command Description Instrument models on which the
command is valid, parameter ranges,
and supported variables.
REFERENCE LEVEL
***.*dBm
Sets the reference level valueused
for LOG scaling.
–90.0 to 30.0dBm (0.1 step)
REFERENCE LEVEL
***.*##
Sets the reference level value
used for LIN scaling

BASE LEVEL **** Lower value for linear scale setting.
Use units set under REF LEVEL.
If exceeds 90% of upper units of
scale, execution error results
0 to 900 (0.1 step)
PEAK->REF LEVEL Sets peak level of the waveform
on the active trace to the
reference level value
AUTO REF LEVEL ### Executes after each sweep
finishes. Selects ON/OFF for the
<PEAK→REFLEVEL>function.
###: ON/OFF
LEVEL UNIT ###### Sets the unit of a level scale. ###: dBm, dBm/nm
Y SCALE DIVISION
##DIV
Sets the level scale division. ##: 8, 10, 12
1: Generalized variables E, O, T, U, and V are valid only for the AQ6370C/AQ6370D/
AQ6375B.
Note
For the AQ6375/AQ6375B, dBm/nm and W/nm cannot be selected for LEVEL UNIT when the
horizontal axis is wavenumber. (DBM/NM parameters cannot be set. )
