Example:
If the "A Trigger" tab is selected in the "Events" tab, and the trigger level for Ch1 is 70
mV, the event coupling sets the trigger levels for Ch1 in the B- and R-events also to
70 mV.
SCPI command:
TRIGger<m>:ECOupling on page 456
Delay
Sets the time the instrument waits after an A-event until it recognizes B-events.
SCPI command:
TRIGger<m>:SEQuence:DELay on page 484
Wait for one or more B-events
Sets the number of B-events to be fulfilled after an A-event. The last B-event causes the
trigger. The waiting time for B-events can be restricted with a reset condition: timeout or
reset event.
SCPI command:
TRIGger<m>:SEQuence:COUNt on page 484
Enable reset by timeout, Reset timeout
If enabled, the instrument waits for the specified time for the specified number of B-
events. If no trigger occurs during that time, the sequence is restarted with the A-event.
SCPI command:
TRIGger<m>:SEQuence:RESet:TIMeout[:ENABle] on page 485
TRIGger<m>:SEQuence:RESet:TIMeout:TIME on page 485
Enable reset event
If enabled, the trigger sequence is restarted by the R-event if the specified number of B-
event does not occur before the R-event conditions are fulfilled.
SCPI command:
TRIGger<m>:SEQuence:RESet:EVENt on page 485
3.3.5 Trigger Position
The horizontal position is the location of the trigger in the waveform record. It is defined
by two parameters: the "Reference point" and the "Trigger offset". They determine how
much the instrument acquires before and after the trigger, and which data is shown in
the diagram.
