Keysight Technologies 8163A/B Programming Manual page 185

response: 4 byte Intel floating point; transition speed in dB/s.
example:
INP1:ATT:SPE?
affects: All attenuator modules.
command: :INPut[n][:CHANnel[m]]:WAVelength
syntax: :INPut[n][:CHANnel[m]]:WAVelength<wsp><value>[PM | NM | UM| MM | M] | MIN | MAX | DEF
description: Sets the attenuator module's operating wavelength.
This value is used to compensate for the wavelength dependence of the filter, and to calculate a wavelegth dependent offset
from the user offset table (if enabled).
parameters: <value>
MIN | MAX | DEF
response: none
example: INP1:WAV +1.55000000E-006
affects: All attenuator modules.
command: :INPut[n][:CHANnel[m]]:WAVelength?
syntax: :INPut[n][:CHANnel[m]]:WAVelength?<wsp>MIN | MAX | DEF
description: Without the optional parameter, queries the operating wavelength of the attenuator.
parameters: MIN | MAX | DEF
response: 4 byte Intel floating point; wavelength in m.
example:
INP1:WAV
affects: All attenuator modules.
command: :OUTPutn[:CHANnel[m]]:APMode
syntax: :OUTPutn[:CHANnel[m]]:APMode<wsp><OFF(0) | ON(1)>
description: The use of this command is optional and has no effect on operation.
Included for compatibility with Keysight 8156A mainframe.
