Remote command:
[:SOURce<hw>]:BB:NR5G:TRIGger:EXECute on page 265
Trigger Source
The following sources of the trigger signal are available:
●
"Internal"
The trigger event is executed manually by the "Execute Trigger".
●
"Internal (Baseband A/B)"
The trigger event is provided by the trigger signal from the other basebands.
If common trigger settings are applied, this trigger source is disabled.
●
"External Global Trigger"
The trigger event is the active edge of an external trigger signal provided and con-
figured at the USER x connectors.
●
"External Local Trigger"
The trigger event is the active edge of an external trigger signal provided and con-
figured at the local T/M/C connector.
With coupled trigger settings, the signal has to be provided at the T/M/C1/2/3 con-
nectors.
●
"External Local Clock"
The trigger event is the active edge of an external local clock signal provided and
configured at the local T/M/C connector.
With coupled trigger settings, the signal has to be provided at the T/M/C1 connec-
tor.
●
"Baseband Sync In"
Option: R&S SMW-B9
In master-slave mode, slave instruments are triggered by the active edge of the
synchronization signal.
"External Local Clock/Trigger" require R&S SMW-B10.
Remote command:
[:SOURce<hw>]:BB:NR5G:TRIGger:SOURce on page 261
Sync. Output to External Trigger/Sync. Output to Trigger
Enables signal output synchronous to the trigger event.
●
"On"
Corresponds to the default state of this parameter.
The signal calculation starts simultaneously with the trigger event. Because of the
processing time of the instrument, the first samples are cut off and no signal is out-
put. After elapsing of the internal processing time, the output signal is synchronous
to the trigger event.
