:TRIGger[n][:CHANnel[m]]:INPut
:TRIGger[n][:CHANnel[m]]:INPut<wsp><trigger response>
Sets the incoming trigger response and arms the module.
IGNore: Ignore incoming trigger.
SMEasure: Start a single measurement. If a measurement function is active, see
":SENSe[n][:CHANnel[m]]:FUNCtion:STATe" on page 100, one sample is
performed and the result is stored in the data array, see
":SENSe[n][:CHANnel[m]]:FUNCtion:RESult?" on page 97.
CMEasure: Start a complete measurement. If a measurement function is active,
see":SENSe[n][:CHANnel[m]]:FUNCtion:STATe" on page 100, a complete
measurement function is performed.
NEXTstep: Perform next step of a stepped sweep.
SWStart: 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]" on page 145. 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" on page 100.
NOTE: If a trigger signal arrives at the Input Trigger Connector at the same time
that the :SENSe[n][:CHANnel[m]]:FUNCtion:STATe 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.

All Agilent 8163A/B series power meter modules, Agilent 8161x series return loss modules,
and attenuators with power control.
If you use the Agilent 816x VXIplug&play Instrument Driver, you can trigger power measure-
ments using HP 8153A Series power meters.
Can only be sent to master channel, slave channel is also affected.
