)

This function simplifies arming the trigger. It supports only the LEVEL trigger types

and does not allow more than one channel to have a trigger applied to it. Any

previous pulse width qualifier is cancelled.

Applicability

Arguments

handle, the handle of the required device.

direction, the direction in which the signal must move to cause a

delay, the time, in sample periods, between the trigger occurring

and the first sample being taken.

autoTrigger_ms, the number of milliseconds the device will wait if

no trigger occurs.
