The order may vary depending on the available instruments. It is recommended to use the "INSTRUMENT_INDEX" and "INSTRUMENT_ID" properties to determine the appropriate cardid value to use. timeout: the longest time in seconds that the driver will wait for a response before declaring an error Sets hardware parameters Parameters bname: the name (or description or ID) of the instrument to use for acquisition (as returned by the "INSTRUMENT_ID" property) timeout: the longest time in seconds that the driver will wait for a response before declaring an error Sets program parameters Parameters buffer: warn: format: this is the size of the FIFO buffer in kilobytes for holding spectra in memory. This parameters is normally set to 4096 true of false field for the file overwrite warning. If true, the user must confirm file overwrites before they occur 0 - Float IEEE (recommended) 1 - New SPC GRAMS format save_option: 0 - to save full spectral range, 1 - to save specified spectral range Sets saturation parameters Parameters max_amplitude: maximum allowed interferogram ZPD amplitude. This value is used for detecting saturation and computing percent of maximum in align mode sigma_min: start of out of band region in cm -1 for linearity and optical saturation test sigma_max: end of out if band region in cm -1 for linearity and optical saturation test threshold: highest allowed value for the ratio of the average band intensity with the maximum spectral intensity in percentage 36 Bomem-GRAMS User's Guide
