14.20 TRIGger subsystem
The TRIGger system contains the commands for selecting the trigger source for the
RF and LF sweep.
You can work with an internal or with an externally applied trigger signal. In this case,
use the commands in the SOURce:INPut subsystem to configure the signal.
The trigger system of the R&S SMA100B is a simplified implementation of the SCPI
trigger system. The TRIGger system differs from the SCPI system as follows:
●
No INITiate command; the instrument behaves as if INITiate:CONTinuous
ON were set.
●
Under TRIGger several sweep subsystems exist.
●
The trigger source names correspond directly to the various settings of manual
control. SCPI uses different names which are also accepted by the instrument. The
SCPI names should be used if compatibility is an important consideration.
In addition to these commands, see more trigger-related commands in the modulation
and RF signal subsystems.

R&S proprietary value name SCPI conform value name Parameter in manual control
AUTO IMMediate "Auto" mode
SINGle BUS "Single" mode.
EXTernal EXTernal "Ext Single" and "Ext Step" mode.
Use command LFO:SWEep:MODE
to select between the two sweep
modes.
EAUTo - "Ext Start/Stop" mode.
