GER 1500 USER MANUAL

APPENDICES 35Averaging = 1Si integration speed = 1Optic = 1Scan mode = 1When configuring the DFOV1500.INI file, it is important to get the serial numbers and com ports of the instrumentdesignated as the “Target” and “Reference” in the correct order. In the example above:• GER1500 serial number 2002, connected on the PC’s Com port 4, is the “Target” instrument.• GER1500 serial number 2003, connected on the PC’s Com port 6, is the “Reference” instrument.Also, when using the DFOV PC Data Acquisition Software, both sets of the instrument’s Calibration Files must beinstalled in the software’s System directory.Calibration File FormatsThere are three types of supplied calibration files.A single Wavelength Calibration file contains information that maps channel numbers to their correspondingwavelength.Multiple Radiance Calibration files contain information that calibrates each channel’s digital counts to a radiometricstandard. There is one Radiance Calibration file for each fore optic supplied with the GER 1500.A single (optional) foreoptic name configuration file. This may be used to create a non-standard list of names forcustom foreoptics.WAVELENGTH CALIBRATION FILEWavelengths Calibration File: WV15yyyy.CAL, where yyyy is the instrument serial number. This file contains a singlecolumn of ASCII data that represents the center wavelength of detector element. There are 512 entries in this file,corresponding to the 512 channels.EXAMPLE (truncated):279.94281.68283.42285.16286.90288.64290.38292.12293.85295.59297.32299.06300.80302.53304.26GER 1500 USER MANUAL, REVISION 3.7
