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
• -10090 (GPIB_ERROR_OCCURRED): A GPIB communications error occurred
• -10100 (INVAL_PARAM): An invalid input parameter is specified

QTsweep82 user module
This user module uses the 595 to determine the equilibrium point for a device by measuring
quasistatic capacitance using different delay times.
Usage
status = QTsweep82(double Test_Bias, int LeakageCorrection, double Hold_time,
double V-Step, char *InstldStr, int InputPin, int OutPin, double Delay_Max, int
Range, double *CQS, int, CQS_ArrSize, double *QT, int QT_ArrSize, double
*Delay_time, int Delay_time_ArrSize);
Returned values are placed in the Analyze sheet; see Details
Voltage bias for capacitance measurements (−120 V to +120 V)
Enable:
Hold time at the beginning of the sweep (0 s to 200 s; default 5)
Step voltage size: ±0 V, ±0.01 V, ±0.02 V, ±0.05 V, ±0.1 V
KCon instrument ID; default is CMTR1; can be CMTR1 to CMTR4, depending on
your system configuration
The DUT pin to which the 5951 input terminal is attached (−1 to 72); if a value of
less than 1 is specified, no switch matrix connections are made
The DUT pin to which the 5951 output terminal is attached (−1 to 72); if a value
of less than 1 is specified, no switch matrix connections are made
Maximum delay time: 1 s to 199.99 s (default 10 s)
The measurement range for the 595 to use: 1 to 3; see Details
