-SCS Parameter Analyzer Reference Manual Appendix B: Using a Model 590 C-
4200A-901-01 Rev. C / February 2017 B-17
Procedure
1. You are prompted to open the circuit so that an offset capacitance measurement can be made, if
needed.
2. If a cable compensation file is specified, the compensation information in that file for the selected
range and frequency is loaded. If not, instrument default compensation is used.
3. The capacitance and conductance are measured.

CtSweep590 user module
The CtSweep590 routine performs a capacitance versus time (C
t
) sweep using the Keithley Instruments 590 C-V
Analyzer. You can make an offset correction measurement and use cable compensation.
Usage
status = CtSweep590(char *CabCompFile, char *InstIdStr, int InputPin, int OutPin,
int OffsetCorrect, int Frequency, double DefaultBias, double Bias, double
StartTime, double StepTime, double Range, int Model, int Filter, int Count, int
ReadingRate, double *C, int Csize, double *G_or_R, int G_or_Rsize, double *T,
int Tsize);

The DUT pin to which the 590 input terminal is attached (−1 to 72); if a value of less
than 1 is specified, no switch matrix connection is made; see Details

less than 1 is specified, no switch matrix connection is made; see Details
Determines if an offset correction measurement should be made:
• Do not make offset measurement: 0
•
Make offset measurement: 1
The measurement frequency to use:
• 100 kHz: 0
•
The DC bias to use for the measurement:
−
The DC bias that is applied during a sweep: −20 V to +20 V
The time that occurs on the first bias step, from the point the instrument is first
triggered until the first step time: 0.001 s to 65 s
The time period after a transition to a new bias step and before the instrument
begins a measurement: 0.001 s to 65 s
The measurement range to use in F: 2E-12, 20E-12, 200E-12, or 2E-9; see Details
• Series model: 0
• Parallel model:
Enable or disable the analog filter, which can minimize the amount of noise that
appears in the readings; however, it increases the measurement time:
• Disable the filter: 0
•
The number of readings per sweep: 1 to 1350
Selects the reading rate used to acquire the measurements: 0 to 4; see Details
