If the file defined for CabCompFile does not exist, or there is no path specified (null string), the
default compensation parameters are used. When entering the path, use two backslash (\\)
characters to separate each directory. For example, if your cable file is in
C:\calfiles\590cal.dat, you enter the following:
C:\\calfiles\\590cal.dat
If a switch matrix to route signals is being controlled by a connection action (for example, connect),
there is no need to connect InputPin and OutPin. Set these parameters to 0.
The return values from status can be:
• 0: OK.
• -10021 (COMP_FILE_NOT_EXIST): The specified compensation file does not exist.
• -10022 (KI590_NOT_IN_KCON): There is no CMTR defined in your system configuration.

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);
status
Returned values are placed in the Analyze sheet; see Details
CabCompFile
The complete name and path for the cable compensation file; see Details
instr_id
The CMTR instrument ID; this can be CMTR1 through CMTR4, depending on the
configuration of your system
frequency
The frequency of the correction constant: 0 = 1 MHz; 1 = 100 kHz
range
The range of the correct constant; see Details
