If it observes lost trigger events, the analyzer increments a dedicated counter and
records the events in a dedicated log, which is updated after every sweep. Use the
clickable link in the message popup to open the
of the system "Info"
dialog, which displays the lost trigger event log. From there you can also clear the log
(and reset the counter at the same time).

Source
In
FreeRun / External / Manual / Multiple TriggersExternal
trigger mode, this setting
selects one of the possible external trigger sources. Trigger In A and pin 2 of the User
Port connector are equivalent.
Remote command:
Delay
Specifies a delay time between the trigger event and the start of the next measurement
sequence.
The specified "Delay" must be zero or positive, so that the trigger event precedes the
start of the measurement (post-trigger).
If "Multiple Triggers" is active, the "Delay" can be selected individually using the

Remote command:
TRIGger<Ch>[:SEQuence]:HOLDoff
Signal Type
Specifies the "External" trigger mode in detail.
●
"Rising Edge"/"Falling Edge"
means that the rising/falling slope of every external
trigger pulse can trigger a single measurement sequence.
●
"Active High"/"Active Low"
means that the analyzer measures in "FreeRun"
mode as long as the external trigger signal is high/low. The measurement is dis-
continued when the trigger signal changes to low/high.
