Tektronix Keithley 4200A-SCS User Manual

Section 6: Using a Model 82 C-V System Model 4200A-SCS Prober and External Instrument Control
6-42 4200A-913-01 Rev. A December 2020
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
If you are controlling a switch matrix to route signals using a connection UTM (for example,
“connect”), you do not need connect InputPin and OutputPin. Set these parameters to 0.

SIMCVsweep82 user module
The SIMCVsweep82 routine performs a simultaneous capacitance versus voltage (C-V) sweep using
the Keithley Instruments 82 C-V System.
Usage
status = SIMCVsweep82(double Frequency, double Default_Bias, double Stress_Time, double
VSub_Start, double VSub_Stop, double VSub_Step, int Range595, int Range590, int
Model590, int Filter, double Delay595, int LeakageCorrection, char *CabCompFile, int
OffsetCorrect, char *InstldStr, int InputPin, int OutPin, double *CHF, int
CHF_ArrSize, double *VSub, int VSub_ArrSize, double *CQS, int CQS_ArrSize, double
G_or_R, int G_or_R_ArrSize, double *QT, int QT_ArrSize);
status
Returned values are placed in the Analyze sheet; see Details
