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
