Arm - Digital Modulation
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:DM:TRIGger:ARM:EXECute on page 554
Execute Trigger - Digital Modulation
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:DM:TRIGger:EXECute on page 555
Trigger Source - Digital Modulation
Selects trigger source.
"Internal"
The trigger event is executed by "Execute Trigger". As a precondition
a trigger mode other than "Auto" must be selected.
"External
(TRIGGER)"
The trigger event is executed with the aid of the active edge of an exter-
nal trigger signal. The trigger signal is supplied via the TRIGGER con-
nector.
The polarity, the trigger threshold and the input impedance of the TRIG-
GER input can be set in the GLOBAL TRIGGER SETTINGS menu.
SCPI command:
[:SOURce<hw>]:BB:DM:TRIGger:SOURce on page 558
Sync. Output to External Trigger
(enabled for "Trigger Source" External)
Enables/disables output of the signal synchronous to the external trigger event.
For or two or more R&S SMBVs configured to work in a master-slave mode for synchro-
nous signal generation, configure this parameter depending on the provided system trig-
ger event and the properties of the output signal. See table 5-9 for an overview of the
required settings.
