The signal output begins after elapsing of the processing time. Signal output starts
with sample 0. The complete signal is output.
This mode is recommended for triggering of short signal sequences. Short sequen-
ces are sequences with signal duration comparable with the processing time of the
instrument.
In primary-secondary instrument mode, this setting ensures that once achieved, syn-
chronization is not lost if the baseband signal sampling rate changes.
Remote command:
[:SOURce<hw>]:BB:DVB:TRIGger:EXTernal:SYNChronize:OUTPut
External / Trigger Inhibit
Applies for external trigger signal or trigger signal from the other path.
Sets the duration with that any following trigger event is suppressed. In "Retrigger"
mode, for example, a new trigger event does not cause a restart of the signal genera-
tion until the specified inhibit duration does not expire.
For more information, see chapter "Basics" in the R&S
SMW user manual.
Remote command:
[:SOURce<hw>]:BB:DVB:TRIGger[:EXTernal]:INHibit
[:SOURce<hw>]:BB:DVB:TRIGger:OBASeband:INHibit
External / Trigger Delay
Delays the trigger event of the signal from:
●
The external trigger source
●
The other path
●
The other basebands (internal trigger), if common trigger settings are used.
Use this setting to:
●
Synchronize the instrument with the device under test (DUT) or other external devi-
ces
●
Postpone the signal generation start in the basebands compared to each other
●
Compensate delays and align the signal generation start in multi-instrument setup
For more information, see chapter "Basics on ..." in the R&S
SMW user manual.
