description:
Inquires the current sensor power unit
parameters:
none
response:
An
integer
value:
0: Current power units are dBm.
1: Current power units are Watts.
example:
sens1:pow:unit?
->
+1<END>

command:
:SENSe[
n
]:[CHANnel[
m
]]:POWer:WAVelength
syntax:
:SENSe[
n
]:[CHANnel[
m
]]:POWer:WAVelength<wsp><value>|MIN|MAX|DEF [PM|NM|UM|MM|M]
description:
Sets the sensor wavelength. Frequent use of this command can conflict with the timing of autoranging in some
configurations. Autorange can be disabled before and enabled after the command if needed.
parameters:
The wavelength as a
float
value in meters.
