Model 4200A-SCS Parameter Analyzer Reference Manual Appendix B: Using a Model 590 C-V Analyzer4200A-901-01 Rev. C / February 2017 B-27CvSweep590 user moduleThe CvSweep590 routine does a capacitance versus voltage (C-V) sweep using the Keithley Instruments 590 C-VAnalyzer. You can make an offset correction measurement and use cable compensation.Usagestatus = CvSweep590(char *CabCompFile, char *InstIdStr, int InputPin, int OutPin,int OffsetCorrect, int Waveform, double FirstBias, double LastBias, doubleStepV, 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 DetailsCabCompFile The complete name and path for the cable compensation file; see DetailsInstIdStr The CMTR instrument ID; CMTR1, CMTR2, CMTR3, or CMTR4, depending on yoursystem configurationInputPin The DUT pin to which the 590 input terminal is attached (−1 to 72); if a value of lessthan 1 is specified, no switch matrix connection is made; see DetailsOutPin The DUT pin to which the 590 output terminal is attached (−1 to 72); if a value ofless than 1 is specified, no switch matrix connection is made; see DetailsOffsetCorrect Determines if an offset correction measurement should be made:• Do not make offset measurement: 0• Make offset measurement: 1Waveform Selects either the single staircase or dual staircase waveform:• Single: 1• Dual: 2FirstBias The starting voltage for the sweep: −20 V to +20 VLastBias The last voltage used in the sweep: −20 V to +20 VStepV 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 parametersFrequency The measurement frequency to use:• 100 kHz: 0• 1 MHz: 1DefaultBias The DC bias that is applied before and after a sweep: −20 V to +20 VStartTime The time that occurs on the first bias step, from the point the instrument is firsttriggered until the first step time: 0.001 s to 65 sStepTime The time period after a transition to a new bias step and before the instrumentbegins a measurement: 0.001 s to 65 sRange The measurement range to use in F: 2E-12, 20E-12, 200E-12, or 2E-9; see DetailsModel Measurement model:• Series model: 0• Parallel model: 1Filter Enable or disable the analog filter, which can minimize the amount of noise thatappears in the readings; however, it increases the measurement time:• Disable the filter: 0• Enable the filter: 1ReadingRate Selects the reading rate used to acquire the measurements: 0 to 4; see DetailsC Output: The measured array of capacitance values
