In instruments equipped with 2xR&S SMW-B10, 1xR&S SMW-B14 and R&S SMW-
B13T.
●
In primary-secondary instrument mode
See Chapter 10.3.1, "Connecting Multiple Instruments in Primary-Secondary
Instrument Mode", on page 640.
To enable simultaneous signal generation in all basebands in any of these cases, the
R&S SMW couples automatically the trigger settings in all available basebands. It is
sufficient to adjust the trigger settings, like trigger source and trigger mode in one of
the basebands; the R&S SMW applies them automatically to all other. An arm or a
restart trigger event applies to all basebands, too. You can still apply different delay to
each of the triggers individually.
Example:
This example shows schematically the distribution of the trigger signal in instrument
with the following configuration:
●
"System Configuration > Entity = 1", 4x4 MIMO configuration (1x4x4) and "Base-
band Source Config > Separate".
●
"Baseband A > ... > Trigger In > Trigger Source > Ext. Global Trigger 1"
Each of the "Baseband B/C/D" adopts the same trigger source automatically.

●
"Baseband A > ... > Trigger In > Trigger Mode > Retrigger"
The "Baseband B/C/D" adopt the same trigger mode automatically.
