The following timing diagram represents the acquisition process for an External Edge Trigger event.
The single strobe function for the case of an edge trigger event is similar to that of a software trigger. The single strobe delay is relative to the end of the Exter-
nal Edge Trigger Delay.
Also, the continuous strobe signal function is the same as that of the software trigger and starts with the start of the integration cycle. Again, only full periods
are exercised during integration time.
Since the trigger pulse width determines the integration time, the trigger signal must be high for a minimum time. Specifically, the minimum trigger pulse width
must satisfy the following condition, otherwise an error will occur and the received spectral values will be all 0’s.
