Tektronix Keithley 4200A-SCS User Manual

Section 4: Using a Model 590 C-V Analyzer Model 4200A-SCS Prober and External Instrument Control
4-26 4200A-913-01 Rev. A December 2020
CvSweep590 user module
The CvSweep590 routine does a capacitance versus voltage (C-V) sweep using the Keithley Instruments 590 C-V
Analyzer. You can make an offset correction measurement and use cable compensation.
Usage
status = CvSweep590(char *CabCompFile, char *InstIdStr, int InputPin, int OutPin, int
OffsetCorrect, int Waveform, double FirstBias, double LastBias, double StepV, int
Frequency, double DefaultBias, double StartTime, double StepTime, double Range, int
Model, int Filter, int ReadingRate, double *C, int Csize, double *V, int Vsize, 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
Waveform
Selects either the single staircase or dual staircase waveform:
▪ Single: 1
▪ Dual: 2
FirstBias
The starting voltage for the sweep: −20 V to +20 V
LastBias
The last voltage used in the sweep: −20 V to +20 V
StepV
The voltage step size: −20 V to +20 V; the value of
((LastBias − FirstBias) / StepV) + 1 must be less than or equal to the Csize,
Vsize, G_or_Rsize, and Tsize parameters
Frequency
The measurement frequency to use:
▪ 100 kHz: 0
▪ 1 MHz: 1
DefaultBias
The DC bias that is applied before and after 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
