Measurement Operations & Settings
4
response:
4 byte Intel floating point; transition speed in dB/s.
example:
INP1:ATT:SPE?
->
2
<END>
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
The wavelength in meters (if you do not specify a unit).
Sets the wavelength to the module limits, or the module default.
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
Queries the operating wavelength limits, or the module default.
response:
4 byte Intel floating point; wavelength in m.
example:
INP1:WAV
->
+1.55000000E-006<END>
affects:
All attenuator modules.
command:
:OUTPut
n
[:CHANnel[
m
]]:APMode
syntax:
:OUTPut
n
[: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.
