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.

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
(TRIGGER 1 /
2)"
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 connector.
The polarity, the trigger threshold and the input impedance of the
TRIGGER input can be set in the "Global Trigger/Clock Settings" dialog.

Sync. Output to External Trigger
(enabled for "Trigger Source" External)
Enables/disables output of the signal synchronous to the external trigger event.
For R&S SMBV instruments:
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 5-11 for an overview of the
required settings.
Table 5-11: Typical Applications
System Trigger Application "Sync. Output to External Trig-
ger"
Common External Trigger event for
the master and the slave instru-
ments All instruments are synchronous to
the external trigger event ON
All instruments are synchronous
among themselves but starting the
signal from first symbol is more
important than synchronicity with
external trigger event OFF
Internal trigger signal of the master
R&S SMBV for the slave instru-
ments All instruments are synchronous
among themselves OFF
