IVxi3::AssertTrigger

Note: Keysight's VISA COM does not support a COM server for VXI. The IVxi-related interfaces are listed in this help file because they are included in the global VISA COM library.

Description

Sources a software or hardware trigger dependent on the interface type.  For a VXI device, if the TriggerID property is TRIG_SW, then the device is sent the Word Serial Trigger command; for any other values of the attribute, a hardware trigger is sent on the line corresponding to the value of that attribute. 

For VXI software triggers, TRIG_PROT_DEFAULT is the only valid protocol. For VXI hardware triggers, TRIG_PROT_DEFAULT is equivalent to TRIG_PROT_SYNC.
