TRIGger SME
1038.6002.02 3.124 E-13
3.6.16 TRIGger-System
The TRIGger system contains the commands to select the trigger source and to configure the external
trigger socket. The suffix is only important for the SWEEP subsystem and conforms to the numbering of
the SOURce system:
TRIGger1 = RF generator
TRIGger2 = LFGEN2
The trigger system of the SME is a simplified implementation of the SCPI trigger system. Compared to
SCPI, the TRIGger system shows the following differences:
• No INITiate command, the instrument behaves as if INITiate:CONTinuous ON was set.
• There are several subsystems denoting the different parts of the instrument under TRIGger (SWEep,
LIST, PULSe, MSEQuence, DM).
Further commands as to the trigger system of the SME 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) and 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. :SOURce:FREQuency:MODE SWEep. 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
