Page 23: Sample Experiments
Preparing for Experiments Follow the steps below to configure the USB2000 and OOIBase32 for experiments: 1. Double-check that you have correctly installed the USB2000, installed OOIBase32, and configured the light source and other sampling optics. 2. Open the OOIBase32 application, select Spectrometer | Configure from the menu bar, and double- check that A/D Interface settings are correct. - Page 24 If the signal you collect has too little light, you can increase the light level on scale in scope mode by: • Increasing the integration time • Using a larger diameter fiber • Removing any optical filters USB2000 Operating Instructions...

Page 36: Appendix A: Calibrating The Wavelength Of The Usb2000
This Appendix describes how to calibrate the wavelength of your spectrometer. Though each spectrometer is calibrated before it leaves Ocean Optics, the wavelength for all spectrometers will drift slightly as a function of time and environmental conditions. Ocean Optics recommends periodically recalibrating the USB2000. -

Page 41: Appendix B: Usb2000-Flg Spectrometer
On the USB2000-FLG, Ocean Optics has altered the functionality of the External Hardware Trigger function and reprogrammed the Single Strobe signal function. These alterations of the USB2000 enable you to operate in the Variable Delay Mode without the presence of an external trigger signal. The USB2000-FLG will simulate the signal to trigger the appropriate circuitry in the spectrometer. - Page 42 The strobe signal is a rising edge trigger signal that is TTL High for the entire delay period. See Figure B-2 for a timing diagram. The USB2000-FLG is now configured for operation in Variable Delay Mode. Figure B-1: The Acquisition Parameters Toolbar.
