"Single"
The signal is generated only when a trigger event occurs. Then the signal
is generated once to the length specified at "Signal Duration".
Every subsequent trigger event (internal with "Execute Trigger" or exter-
nal) causes a restart.
SCPI command:
[:SOURce<hw>]:BB:MCCW[:TRIGger]:SEQuence on page 680
Signal Duration
Defines the length of the signal sequence to be output in the "Single" trigger mode. The
unit of the entry is defined under "Signal Duration Unit". It is then possible to output delib-
erately just part of the signal, an exact sequence of the signal, or a defined number of
repetitions of the signal.
SCPI command:
[:SOURce<hw>]:BB:MCCW:TRIGger:SLENgth on page 679
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 modulation signal is generated; a trigger was (internally or exter-
nally) initiated in triggered mode.
If "Armed_Auto" and "Armed_Retrigger" have been selected, generation
of signals can be stopped with the "Arm" button. A new trigger (internally
with "Execute Trigger" or externally) causes a restart.
"Stopped"
The signal is not generated, and the instrument waits for a trigger event
(internal or external).
SCPI command:
[:SOURce<hw>]:BB:MCCW:TRIGger:RMODe on page 678
Arm
Stops signal generation. This button appears only with "Running" signal generation in the
"Armed_Auto" and "Armed_Retrigger" trigger modes.
Signal generation can be restarted by a new trigger (internally with "Execute Trigger" or
externally).
SCPI command:
[:SOURce<hw>]:BB:MCCW:TRIGger:ARM:EXECute on page 677
Execute Trigger
Executes trigger manually. A manual trigger can be executed only when an internal trig-
ger source and a trigger mode other than "Auto" have been selected.
SCPI command:
[:SOURce<hw>]:BB:MCCW:TRIGger:EXECute on page 677
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".
