Measurement Operations & Settings Signal Generation – The SOURce Subsystem
114 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
command:
:OUTPut[n][:CHANnel[m]]:PATH?
syntax: :OUTPut[n][:CHANnel[m]]:PATH?
description: Returns the regulated path.
parameters: none
response: HIGH:
LOWS:
BHR:
BLR:
The High Power output is regulated.
The Low SSE output is regulated.
B
oth outputs are active but only the High Power output is Regulated.
B
oth outputs are active but only the Low SSE output is Regulated.
example: output0:path? → HIGH<END>
affects: Tunable laser modules with two outputs.
command:
:OUTPut[n][:CHANnel[m]][:STATe]
syntax: :OUTPut[n][:CHANnel[m]][:STATe]<wsp>OFF|ON|0|1
description:
NOTE
Switches the laser current off and on.
The laser emits light only when the current is on. Set the state to OFF or 0 to switch the laser
current off. Set the state to ON or 1 to switch the laser current on. The default is for the laser
current to be off.
For attenuator output see page 156
parameters: 0 or OFF:
1 or ON:
switch laser current off
switch laser current on
response: none
example: outp 1
affects: All laser sources, DFB sources, tunable laser modules and return loss modules with an inter-
nal source
command:
:OUTPut[n][:CHANnel[m]][:STATe]?
syntax: :OUTPut[n][:CHANnel[m]][:STATe]?
description:
NOTE
Queries the current state of the laser current.
For attenuator output see page 156
parameters: none
response: A boolean value: 0 – laser current off
1 – laser current on
example: outp? → 1<END>
affects: All laser sources, DFB sources, tunable laser modules and return loss modules with an inter-
nal source
