The single strobe function for the case of an edge trigger event is similar to that of a software trigger. The start of the single strobe
pulse begins with the start of the integration 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.
External Level Trigger
The External Level Trigger mode for the spectrometer waits for a trigger signal on the 16-pin connector. However, in External Level
Trigger mode, the integration time is directly related to the pulse width of the trigger pulse.
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.
