Measurement Operations & Settings
on page 217 describes the :TRIGger command for advanced users using
response:
none
example:
trig 1
command:
:TRIGger[
n
][:CHANnel[
m
]]:INPut
syntax:
:TRIGger[
n
][:CHANnel[
m
]]:INPut<wsp><trigger response>
description:
Sets the incoming trigger response and arms the module.
parameters:
IGNore:

CMEasure:
NEXTstep:
SWStart:
Ignore incoming trigger.
Start a single measurement. If a measurement function is active, see
:SENSe[n][:CHANnel[m]]:FUNCtion:STATe
on page 104, one sample is performed and
the result is stored in the data array, see
:SENSe[n][:CHANnel[m]]:FUNCtion:RESult?
on page 100.
Start a complete measurement. If a measurement function is active,
see
:SENSe[n][:CHANnel[m]]:FUNCtion:STATe
on page 104, a complete measurement
function is performed.
Perform next step of a stepped sweep.
Start a sweep cycle.
You must prearm a wavelength sweep or a measurement function before an action can be triggered:
First, set the incoming trigger response.
Then:
prearm a wavelength sweep using
[:SOURce[n]][:CHANnel[m]]:WAVelength:SWEep:[STATe]
page 176. The wavelength of the tunable laser module is set to the start wavelength of the sweep.
or prearm a measurement function using
:SENSe[n][:CHANnel[m]]:FUNCtion:STATe
NOTE: If a trigger signal arrives at the Input Trigger Connector at the same time that the
:SENSe[n][:CHANnel[m]]:FUNCtion:STATe
on page 104 command is executed, the first measurement value is
invalid. You should always discard the first measurement value in this case.
The module performs the appropriate action when it is triggered.
response:
none
example:
trig1:inp ign
affects:
All tunable laser modules except 81950A, power meters, and return loss modules, and attenuators with power control.
If you use the Keysight 816x VXIplug&play Instrument Driver, you can trigger power measurements using HP 8153A Series
power meters.
dual sensors:
Can only be sent to master channel, slave channel is also affected.
