read by the user. As long as the trigger level remains active in a logic one state, back-to-back acquisitions can occur, as in the Normal
mode, until the trigger transitions to an inactive level. As in normal mode, no further spectra are acquired until the original spectrum
is read by the user.
External Hardware Edge Trigger Mode
In the External Hardware Edge Trigger mode, a rising edge detected by the spectrometer from the External Trigger input starts the
integration period specified through the software interface. After the integration period, the spectrum is retrieved and is ready to be
read by the user. If another trigger is sent a new integration cycle will begin. If a spectrum request is not received before the
integration cycle has ended then that data will be deleted and a new trigger and spectrum request is required. Only one acquisition
will be performed for each External Trigger pulse, no matter what the pulse’s duration is. No further spectra are acquired until the
original spectrum is read by the user.
