(P/N 753800, hereinafter called the File Structure Manual), available on the GammaVision start menu.
The
.CHN
file format is the format used by our MAESTRO MCA emulator application. It saves the live time, real time, acquisition start time, MCB and sample descriptions, and calibration (if any); but does not contain the analysis parameter data, the complete calibration, or other data needed for nuclide analysis.
The two
.SPC
formats, integer and floating-point, are identical except for the format of the spectrum data. The integer
.SPC
format should be used unless the files are to be used by earlier versions of ORTEC programs. The
.SPC
files contain the energy calibration data and the hardware parameters. The integer format stores the spectrum as 4-byte integers and the floating-point format uses the 4-byte exponential format used in the hardware math coprocessor (e.g., 80387) and most languages for the PC. The analysis and calibration formats are defined in the File
Structure Manual.
The ASCII
.SPE
format is used by the Comprehensive Test Ban Treaty Organization (CTBTO).
NOTE
Before using the Acquire/Download Spectra command, or the Move feature on a supported instrument’s Field Data tab, be sure to select the Save File Format you wish to use for the downloaded spectra.
