LoadCableCorrectionConstants

LoadCableCorrectionConstants reads the cable compensation parameters for the range and frequency
specified from the cable compensation file and sends these parameters to the 590.
Usage
status = LoadCableCorrectionConstants(char *CabCompFile, char *instr_id,
*frequency, int range);

Details
If the file specified by CapCompFile does not exist, it is created. The path that you specify must
exist. When entering the path information, be sure to use two \ characters to separate each directory
level. For example, if your cable compensation file is in file C:\calfiles\590cal.dat, you would
enter C:\\calfiles\\590cal.dat.
