IM AQ6370C-17EN
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
1.00pW to 1000mW
(1.00 to 9.99 [pW, nW, μW, mW] :0.01
step
10.0 to 99.9(100)[pW, nW, μW, (mW)]
:0.1 step
100 to 999 [pW, nW, μW, mW] : 1
step)
## is , pW, nW, μW, mW (select one of
the above)

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 → REF LEVEL> 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. )
