Function Block and Operation Theory
3.9.3 External Digital Trigger
PCIe-7350 supports external digital trigger mode to start or pause
an acquisition or generation operation. PCIe-7350 supports two
trigger sources, internal software trigger and external digital trig-
ger. The digital pattern acquisition or generation will start upon a
software command or an external digital trigger signal to start or
pause the process. The PCIe-7350’s Application Function I/O
(AFI) can be configured as the external digital trigger source.
