"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 the table below for an overview of
the required settings.
Table 5-12: 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
"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.
