EXTernal will output a burst
waveform after each external
trigger pulse. Any additional
trigger pulse signals before the
end of the burst are ignored.
If the APPLy command was used, the source is
automatically set to IMMediate.
The *OPC/*OPC? command/query can be used to
signal the end of the burst.
If the trigger source is set to manual, the function
generator outputs a burst count waveform with
the specified number of cycles each time the
trigger signal * TRG is received. The function
generator stops and waits for the next trigger after
the specified number of cycles has been output.
You can configure the function generator to use an
internal trigger to start a burst or send a trigger
signal from the rear panel port connector by
pressing the front panel key and you can also send
a trigger command * TRG through the remote
interface to provide an external trigger source.
