"Internal (Base-
band A/B)"
(two-path instruments only)
The trigger event is executed by the trigger signal from the second path
"External
(TRIGGER 1 /
2)"
The trigger event is executed with the aid of the active edge of an external
trigger signal.
The trigger signal is supplied via the TRIGGER connector.
The polarity, the trigger threshold and the input impedance of the TRIG-
GER input can be set in the "Global Trigger/Clock Settings" dialog.
SCPI command:
[:SOURce<hw>]:BB:MCCW:TRIGger:SOURce on page 679
Sync. Output to External Trigger
(enabled for Trigger Source External)
Enables/disables output of the signal synchronous to the external trigger event.
"On"
Corresponds to the default state of this parameter.
The signal calculation starts simultaneously with the external trigger
event but because of the instrument’s processing time the first samples
are cut off and no signal is outputted. After elapsing of the internal pro-
cessing time, the output signal is synchronous to the trigger event.
"Off"
The signal output begins after elapsing of the processing time and starts
with sample 0, i.e. the complete signal is outputted.
This mode is recommended for triggering of short signal sequences with
signal duration comparable with the processing time of the instrument.
