timeout
Maximum amount of time in seconds to wait for the trigger
Details
This function waits up to
timeout
seconds for a trigger on the active command interface. A
command interface trigger occurs when:
•
A GPIB GET command is detected (GPIB only)
•
A VXI-11 device_trigger method is invoked (VXI-11 only)
•
A

If one or more of these trigger events were previously detected, this function returns immediately.
After waiting for a trigger with this function, the event detector is automatically reset and rearmed.
This is true regardless of the number of events detected.
