Trigger Source
Selects trigger source. This setting is effective when a trigger mode other than "Auto"
has been selected.
●
"Internal"
The trigger event is executed by "Execute Trigger".
●
"External"
The trigger event is the active edge of an external trigger signal, supplied at the
TRIGGER connector.
Use the "Global Trigger/Clock Settings" dialog to define the polarity, the trigger
threshold and the input impedance of the trigger signal.
Remote command:
[:SOURce<hw>]:BB:GNPR:TRIGger:SOURce

Sync. Output to External Trigger
Enables signal output synchronous to the trigger event.
●
"On"
Corresponds to the default state of this parameter.
The signal calculation starts simultaneously with the trigger event. Because of the
processing time of the instrument, the first samples are cut off and no signal is out-
put. After elapsing of the internal processing time, the output signal is synchronous
to the trigger event.
●
"Off"
The signal output begins after elapsing of the processing time. Signal output starts
with sample 0. The complete signal is output.
This mode is recommended for triggering of short signal sequences. Short sequen-
ces are sequences with signal duration comparable with the processing time of the
instrument.
