TRIGger System
The TRIGger system contains the commands to select the trigger source and to configure the external
trigger socket. The trigger sources for the individual signal sources (RF, LFGen) are distinguished by a
numerical suffix appended to TRIG. The suffix conforms to the numbering of the SOURce system:
TRIGger1 = RF generator
TRIGger2 = LFGen
The trigger system of the R&S SML / R&S SMV03 consists of a simplified implementation of the SCPI
trigger system. Compared to SCPI, the TRIGger system shows the following differences:
• No INIT command, the instrument behaves as if :INIT:CONT ON was set.
• There are several subsystems denoting the different parts of the instrument under TRIGger (SWEep,
PULSe).
Further commands as to the trigger system of the R&S SML / R&S SMV03 can be found in the ABORt
system.

:TRIGger1|2[:SWEep]
All commands to trigger a sweep are under this node. The settings here act on level and
frequency sweeps for RF generator (TRIG1) or LF generator (TRIG2).
:TRIGger1|2[:SWEep][:IMMediate]
The command immediately starts a sweep. Which sweep is executed depends on the respective
Mode setting, e.g. :SOUR:FREQ:MODE SWE. The command corresponds to manual-control
command Execute Single Sweep. This command triggers an event and thus has no *RST value.
Example: :TRIG:SWE:IMM
