Running/Stopped
Displays the status of signal generation for all trigger modes. This display appears only
when signal generation is enabled ("State" On).
"Running" The waveform is output; a trigger was (internally or externally) initi-
ated in triggered mode.
If "Armed_Auto" and "Armed_Retrigger" have been selected, genera-
tion of signals can be stopped with the "Arm" button. A new trigger
(internally with "Execute Trigger" or externally) causes a restart.
"Stopped" The Waveform output is stopped. The instrument waits for an internal
or external trigger event to restart. ARB modulation is disabled (State
Off).
Remote command:
[:SOURce<hw>]:BB:ARBitrary:TRIGger:RMODe?
on page 586
Arm
Stops waveform output. This button appears only with "Running" signal generation in
the "Armed_Auto" and "Armed_Retrigger" trigger modes.
Signal output can be restarted by a new trigger (internally with "Execute Trigger" or
externally).
Remote command:
[:SOURce<hw>]:BB:ARBitrary:TRIGger:ARM:EXECute
on page 583
Execute Trigger
Executes trigger manually. A manual trigger can be executed only when an internal
trigger source and a trigger mode other than "Auto" have been selected.
Remote command:
[:SOURce<hw>]:BB:ARBitrary:TRIGger:EXECute
on page 584
Trigger Source
Selects trigger source. This setting is effective only when a trigger mode other than
"Auto" has been selected.
"Internal" The trigger event is executed by "Execute Trigger".
"External" 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 1/2 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.
Note: For multi segment waveforms, an external trigger source can
be used for cyclical output of the segments. Each trigger event starts
the output of the next segment. After the last segment, the first seg-
ment is output again.
Remote command:
[:SOURce<hw>]:BB:ARBitrary:TRIGger:SOURce
