EndTrigger Input
For applications using a hardware acquisition end trigger, anyone of the system I/O input ports can be selected as the source for the end trigger control circuit of the acquisition channel.
For that usage, use the parameters belonging to the Trigger Control category.
The end trigger source signal can originate from the following type of devices:
- Through a single high-speed differential input port driven by an RS-422 compatible detector.
- Through a single isolated current-sense input port driven by a detector that is not RS-422 compliant.
The selection of the port is primarily based on the electrical style of the sensor device used as End Trigger source.
Possible ports assignments
Sourcing device type |
Default port(s) assignment |
Alternate port assignment(s) |
RS-422 compatible detector |
High-speed diff. input #2 |
High-speed diff. input #1 |
Other detectors |
Isolated input #2 |
Isolated input #1 |
- Any input port and hence any electrical style can be specified for that function.
- The default port assignment is the same as the one for the trigger. This corresponds to the case where a single signal is used for both functions, one edge being the trigger, the opposite edge being the end trigger.
