TRIGger SME

Effect of TRIGger:DM:SOURce and SOURce:ERMes|FLEX|REFL25|POCSag:TACTion on the
sequence of complex digital modulations.
:SOURce:ERM|FLEX|REFl25|POCS:TACTion
TRIGger:DM:SOURce MESSage STARt ONCE
AUTO
MODE ALWAYS
The frames are continuously repeated in the set sequence; the setting under
ERMes|FLEX|REFLex25|POCSag:TACTion is irrelevant
SINGle
MODE SINGLE
A trigger event (key; IEC/IEEE-
bus- command) switches once
from IDLE frame output to
ALPH-, NUM and TONE frame
output.
––
EXT
MODE EXT-SINGLE
An external trigger event
(signal edge at the trigger
connector) switches once from
IDLE frame output to ALPH-,
NUM and TONE frame output.
MODE EXTTRIG-ALWAYS
An external trigger event starts
digital modulation.
Subsequently, the frames are
continuously repeated in the
set sequence.
MODE EXTTRIG
An external trigger event starts
the digital modulation. After the
output of a cycle
(FLEX/REFLex25), a time slice
(POCSAG) or a subsequence
(ERMES) the modulation is
stopped, the SME waits for the
next trigger event.
Example: :TRIG:DM:SOUR AUTO *RST value is AUTO
:TRIGger:LIST
This node contains all commands to trigger a list in the LIST mode.
The commands are only valid for TRIGger1.
:TRIGger:LIST[:IMMediate]
The command immediately starts the processing of a list of the LIST mode. It corresponds to
command EXECUTE SINGLE MODE of the manual control in the LIST menu. This command is
an event and thus has no *RST value.
Example: :TRIG:LIS:IMM
