Tektronix Keithley 4200A-SCS User Manual

Section 4: Using a Model 590 C-V Analyzer Model 4200A-SCS Prober and External Instrument Control
4-18 4200A-913-01 Rev. A December 2020
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);
status
Returned values; see Details
CabCompFile
The complete name and path for the cable compensation file; see Details
InstIdStr
The CMTR instrument ID; CMTR1, CMTR2, CMTR3, or CMTR4, depending on your
system configuration
InputPin
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
OutPin
The DUT pin to which the 590 output terminal is attached (−1 to 72); if a value of
less than 1 is specified, no switch matrix connection is made; see Details
OffsetCorrect
Determines if an offset correction measurement should be made:
▪ Do not make offset measurement: 0
▪ Make offset measurement: 1
Frequency
The measurement frequency to use:
▪ 100 kHz: 0
▪ 1 MHz: 1
DefaultBias
The DC bias to use for the measurement: −20 V to +20 V
Bias
The DC bias that is applied during a sweep: −20 V to +20 V
StartTime
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
StepTime
The time period after a transition to a new bias step and before the instrument
begins a measurement: 0.001 s to 65 s
Range
The measurement range to use in F: 2E-12, 20E-12, 200E-12, or 2E-9; see Details
Model
Measurement model:
▪ Series model: 0
▪ Parallel model: 1
