Ocean Optics Inc. has added triggering functions to its USB2000+ miniature spectrometer to provide accurate timing and synchronization between the spectrometer and other devices. Four low-jitter trigger modes and normal (free-running spectral acquisition) operating modes are now available. In “normal” operating mode, the spectrometer continuously acquires spectra. In external software trigger mode, while the spectrometer is in free-running mode, data collected in the period up to the triggering event is transferred to software. In external hardware level trigger mode, the spectrometer waits for a sharp rise in voltage on the trigger input pin and then acquires spectra until the voltage is removed. In external synchronous trigger mode, it acquires data from an external trigger event until the next time the trigger is activated, at which time it ceases spectral acquisition and begins a new acquisition. In external hardware edge trigger mode, the spectrometer waits for a sharp rise in voltage on the trigger input pin and then acquires one spectrum.
