Model 4200A
-SCS Parameter Analyzer Reference Manual Appendix C:
Using a Keysight 4284/4980A LCR Meter
4200A-901-01 Rev. C / February 2017 C-11
Cmeas4284 User Module
The Cmeas4284 routine measures capacitance and conductance using the Keysight Model 4284A or 4980 LCR
Meter.
Usage
status = Cmeas4284( char *InstIdStr, int LoPin, int HiPin, double SignalLevel,
double Frequency, double BiasV, double Range, int Model, int IntegrationTime,
double *C, double *V, double *G_or_R);
status
Returned values; see Details
InstIdStr
The CMTR instrument ID; CMTR1 or CMTR2 (default), depending on your system
configuration
LoPin
The DUT pin to which the Model 4284A or 4980 low terminal is attached (−1 to 72;
default 0); if a value of less than 1 is specified, no switch matrix connection is made;
see Details
HiPin
The DUT pin to which the Model 4284A or 4980 high terminal is attached (−1 to 72;
default 0); if a value of less than 1 is specified, no switch matrix connection is made;
see Details
SignalLevel
The oscillator output voltage level: 5 mV to 20 V; default 0.045 V
Frequency
Measurement frequency of the sweep: 20 Hz to 1e6 Hz; default 100e3 Hz
BiasV
The DC bias to use for the measurement:
−
40 V to +40 V; default 1.0 V
Range
The measurement range to use (in ohms): 0 (Auto, the default), 100, 300, 1000,
3000, 10000, 30000, or 100000
Model
Measurement model:
Series
or
Parallel
IntegrationTime
The integration time to use:
• Short: 0
• Medium: 1 (default)
•
Long: 2
C
Output: The measured capacitance
V
Output: The bias voltage used
G_or_R
Output:
• Parallel measurement model (G_or_R is the measured conductance): 1
• Series measurement model (G_or_R is the measured resistance):
0
Details
This user module makes a single, fixed-bias capacitance and conductance measurement.
If a switch matrix to route signals is being controlled by a connection action UTM (for example,
connect), there is no need to connect LoPin and HiPin. Set these parameters to 0.
Returned values are placed in the Analyze spreadsheet.
• 0: OK.
• -10000 (INVAL_INST_ID): The specified instrument ID does not exist.
• -10030 (HP4284_NOT_IN_KCON): No Keysight 4284A or Keysight 4980 LCR is defined in your
system configuration.
• -10031 (HP4284_MEAS_ERROR): A measurement error occurred.
