Parameter Value Source of Trigger
ALGorithm Generated by the Algorithm Language function
“interrupt()”
FTRigger Generated on the First Trigger of a multiple “counted
scan” (set by TRIG:COUNT <trig_count>)
SCPlugon Generated by a Signal Conditioning Plug-On (SCP). Do
not use this when Sample-and-Hold SCPs are installed.
TRIGger Generated every time a scan is triggered (see
TRIG:SOUR <trig_source>)
·
FTRigger (First TRigger) is used to generate a single TTLTRG output when
repeated triggers are being used to make multiple executions of the enabled
algorithms. The TTLTRG line will go low (asserted) at the first trigger event and
stay low through subsequent triggers until the trigger count (as set by
TRIG:COUNT) is exhausted. At this point the TTLTRG line will return to its
high state (de-asserted). This feature can be used to signal when the VT1419A has
started running its control algorithms.

OUTPut:TTLTrg<n>[:STATe]
OUTPut:TTLTrg<n>:STATe <ttltrg_cntrl> specifies which VXIbus TTLTRG
line is enabled to source a trigger signal when the module is triggered. TTLTrg<n>
can specify line 0 through 7. For example, …:TTLTRG4 or TTLT4 for VXIbus
TTLTRG line 4.
