External Triggering Options Instructions

Overview

Ocean Optics USB2000, USB2000+, USB4000, HR2000, HR2000+, HR4000, Jaz, Maya, QE65000, NIR

Series, NIRQuest Series, S2000, and S1024DW Spectrometers provide several methods of acquiring data

(see table below). In the Normal mode, the spectrometer is “free running.” That is, the spectrometer is

continuously scanning, acquiring, and transferring data to your computer, according to parameters set in

the software. In this mode, however, there is no way to synchronize the scanning, acquisition, and transfer

of data with an external event. However, trigger pulses for synchronizing an external event with the

spectrometer are available.

To synchronize data acquisition with external events, other modes of acquiring data are available. Each

mode involves connecting an external triggering device to the spectrometer and then applying an external

trigger to the spectrometer before the software receives the data. The length of the integration time and

the source for the integration clock depend upon the mode chosen. All other acquisition parameters are set

in the software.

For spectrometers with FPGA firmware versions of 3.0 or higher, and for spectrometers not covered by

this document, see

New External Triggering Options Instructions for Spectrometers with Firmware

Version 3.0 and Above. Also see the HR4000 and USB4000 Shutter Mode Performance in Hardware

Trigger Mode for more information on external triggering with these spectrometers.

Triggering Mode Description Applicable Spectrometer(s)

Normal Spectrometer acquires spectra continuously. All

External

Software

Integration time is set in the software. Software

receives a trigger event and transmits spectra obtained

in the data acquisition cycle in which the trigger

occurred.

All

External

Hardware

Integration time set via chip in spectrometer (USB

Series/Jaz/HR Series/S2000 D Series) or jumpers

(S2000 series). Spectrometer waits for a sharp rise in

voltage on the trigger input pin, and then acquires

spectra until the voltage is removed.

HR2000/HR2000+/HR4000/

S2000/S1024DW

External

Synchronization

Spectrometer acquires data from an external trigger

event (such as a push button) until the next time the

trigger is activated, at which time the spectrometer

ceases spectral acquisition and begins a new

acquisition. Integration time cannot be set, since the

trigger can fire at random intervals.
