Spectrometer Configuration Files

The Spectrometer Configuration File contains all the settings for your spectrometer and A/D interface.
This file is the most important type of file in OOIBase32 as it controls how your spectrometer
communicates with your computer.

The Spectrometer Configuration File contains extremely important information, such as the type of
spectrometer and A/D converter in use. It includes the serial number of the spectrometer, the interrupt
request of the A/D converter, the base address (I/O range) of the A/D converter, the serial port number for
a SAD500, and the pixel resolution of the SAD500 serial port.

The most important line in a Spectrometer Configuration File is the Initialized line. This line indicates if
you have previously operated the spectrometer successfully. It reads Initialized = 1 if you have
successfully operated the spectrometer, Initialized = 0 if there is a problem. This file also includes the
first and second wavelength calibration coefficients (and a third if you own a spectrometer manufactured
after July 1999), and the wavelength calibration intercept.

The following table contains a list of the additional functions included in a Spectrometer Configuration
File:

NLEnabled

1 if detector linearity correction enabled, 0 if not enabled

SLEnabled

1 if you enabled stray light correction, 0 if disabled

SLConstant

Stray light constant applied

NLCoefs

Detector linearity correction coefficients

ChannelEnabled

1 if spectrometer channel enabled, 0 if not enabled

ReferenceChannel

Reference spectrometer channel used in reference monitoring, 0 for
Master, 1 for Slave 1, etc.
