If CabCompFile does not exist, or if there is no path specified (null string), the default compensation
parameters are used. When entering the path, be sure to use two \ characters to separate each
directory. For example, if your cable file is in:
C:\calfiles\590cal.dat
You would enter:
C:\\calfiles\\590cal.dat
The return values from status can be:
•
0: OK.
•
-10000 (INVAL_INST_ID): The specified instrument ID does not exist
•
-10020 (COMP_FILE_ACCESS_ERR): There was an error accessing the specified cable
compensation file
•
-10021 (COMP_FILE_NOT_EXIST): The specified compensation file does not exist
•
-10023 (KI590_MEAS_ERROR): A measurement error occurred
•
-10090 (GPIB_ERROR_OCCURRED): A GPIB communications error occurred
•
-10091 (GPIB_TIMEOUT): A timeout occurred during communications
•
-10100 (INVAL_PARAM): An invalid input parameter is specified
•
-10101 (ARRAY_SIZE_TOO_SMALL): The specified value for CHF_ArrSize,
G_or_R_ArrSize, V_ArrSize, CQS_ArrSize, or QT_ArrSize was too small for the number
of steps in the sweep
•
-10102 (ERROR_PARSING): There was an error parsing the 590 response
•
-10104 (USER_CANCEL): The user canceled the correction procedure
•
-10045 (KI82_NOT_IN_KCON): KI82 is not in KCon
Procedure
1. If set, you are prompted to open the circuit so that an offset capacitance measurement can be
made.
2. If a cable compensation file is specified, the compensation information in that file for the selected
range and frequency will be loaded. If not, instrument default compensation is used.
3. A simultaneous C-V sweep is made.
