Routing and enabling a trigger
The provided trigger signals are not dedicated to a particular connector. Trigger signals
can be mapped to one or more USER x or T/M connectors.
Use the Local and Global Connector Settings to configure the signal mapping, the
polarity, the trigger threshold and the input impedance of the input connectors.
To route and enable a trigger signal, perform the following general steps:
●
Define the signal source and the effect of a trigger event.
Select the "Trigger In > Mode" and "Trigger In > Source".
●
Define the connector where the selected signal is provided.
Use the Local and Global Connector Settings.

Trigger Settings Common to All Basebands
To enable simultaneous signal generation in all basebands, the R&S SMW couples the
trigger settings in the available basebands in any instrument's configuration involving
signal routing with signal addition. For example, in MIMO configuration, routing and
summing of basebands or of streams.
The icon indicates that common trigger settings are applied.
You can access and configure the common trigger source and trigger mode settings in
any of the basebands. An arm or a restart trigger event applies to all basebands, too.
You can still apply different delay to each of the triggers individually.
Trigger Mode
Selects trigger mode, i.e. determines the effect of a trigger event on the signal genera-
tion.
For more information, refer to chapter "Basics" in the R&S SMW user manual.
●
"Auto"
The signal is generated continuously.
●
"Retrigger"
The signal is generated continuously. A trigger event (internal or external) causes a
restart.
