Keithley 4200A-SCS Reference Manual

Model 4200A
-SCS Parameter Analyzer Reference Manual Appendix C:
Using a Keysight 4284/4980A LCR Meter
4200A-901-01 Rev. C / February 2017 C-9
CvSweep4284 User Module
The CvSweep4284 routine performs a capacitance versus voltage (C-V) sweep using the Keysight
Model 4284A or Model 4980 LCR Meter.
Usage
status = CvSweep4284(char *InstIdStr, int LoPin, int HiPin, double StartV, double
StopV, double StepV, double SignalLevel, double Frequency, double Range, int
Model, int IntegrationTime, double *C, int Csize, double *V, int Vsize, double
*G_or_R, int G_or_Rsize);
status
Returned values; see Details
InstIdStr
The CMTR instrument ID; CMTR1 or CMTR2, depending on your system
configuration
LoPin
The DUT pin to which the 4284A or 4980 low terminal is attached (−1 to 72); if a
value of less than 1 is specified, no switch matrix connection is made; see Details
HiPin
The DUT pin to which the 4284A or 4980 high terminal is attached (−1 to 72); if a
value of less than 1 is specified, no switch matrix connection is made; see Details
StartV
Starting voltage of the sweep:
−
40 V to 40 V
StopV
Ending voltage of the sweep:
−
40 V to 40 V
StepV
The sweep voltage step size: −40 V to +40 V; the value of ((StopV – StartV)/StepV)
+ 1 must be less than or equal to the values for Csize, Vsize, and G_or_Rsize
SignalLevel
The oscillator output voltage level (5e-3 V to 20 V)
Frequency
Measurement frequency of the sweep: 20 Hz to 1e6 Hz
Range
The measurement range to use (in ohms): 0 (Auto), 100, 300, 1000, 3000, 10000,
30000
, or
100000
Model
Measurement model: Series or Parallel
IntegrationTime
The integration time to use:
• Short: 0
• Medium: 1
•
Long: 2
C
Output: The measured array of capacitance values
Csize
A value equal to or greater than the G_or_Rsize number of steps in the sweep or
= ((StopV − StartV)/StepV) + 1; when this function is called from a Clarius UTM,
the value is fixed at 1350
V
Output: The array of voltage biases used in the sweep
Vsize
A value equal to or greater than the G_or_Rsize number of steps in the sweep or
= ((StopV − StartV)/StepV) + 1; when this function is called from a Clarius UTM,
the value is fixed at 1350
G_or_R
Output:
• When the parallel measurement model (1) is selected, G_or_R is the
measured conductance
• When the series measurement model (0) is selected, this is the measured
resistance
G_or_Rsize
A value equal to or greater than the G_or_Rsize number of steps in the sweep or
= ((StopV − StartV)/StepV) + 1; when this function is called from a Clarius UTM,
the value is fixed at 1350
