You can generate input triggers in any of the following ways:
• trigger the Input Trigger Connector on the rear panel of your instrument,
• set <Trigger Configuration> to <Loopback> so that an output trigger 
automatically generates an input trigger, or
• use the 
:TRIGger
 GPIB command, see your mainframe’s Programming Guide. 
How to Use Output Triggering
You can configure Agilent 8163A Series Power Meter modules to output a trigger 
when the instrument performs certain tasks.
To set your module’s Output Trigger Configuration:

measurement begins.
– <Disabled>, the output trigger mode is disabled.
