Tektronix Keithley 4200A-SCS User Manual

Model 4200A-SCS Prober and External Instrument Control Section 6: Using a Model 82 C-V System
4200A-913-01 Rev. A December 2020 6-35
Procedure
1. If set, you are prompted to open the circuit so that an offset capacitance measurement can be
made.
2. If a cable compensation file is specified, the compensation information in that file for the selected
range and frequency will be loaded. If not, instrument default compensation is used.
3. A C-t sweep is performed.

DisplayCableCompCaps82 user module
This user module is used for Model 82 cable compensation. When this test is run, the nominal
capacitance source values saved by the SaveCableCompCaps82 user module are placed into a
spreadsheet for viewing.
Usage
status = DisplayCableCompCaps82(char *CabCompFile, double *Range, int RangeSize, double
*Values100 k, int Values100 kSize, double *Values1M, int Values1MSize);
status
Returned values are placed in the Analyze sheet; see Details
CabCompFile
The complete name and path for the cable compensation file; see Details
Range
Output; an 8-element array that receives the nominal range values
RangeSize
The size of the Range array; set to 8
Values100k
Output; an 8-element (fixed) array that receives the nominal capacitor values used
for the cable compensation at the 100 kHz frequency
Values100kSize
The size of the Values100k array; set to 8
Values1M
Output; an 8-element (fixed) array that receives the nominal capacitor values used
for the cable compensation at the 1 MHz frequency
Values1MSize
The size of the Values1M array; set to 8
Details
The DisplayCableCompCaps82 user module reads the nominal cable compensation values that
are stored in the compensation file and returns them to the calling function. In the case of Clarius, it
returns the values to the UTM data sheet.
The default parameters for this user module are shown in the following figure. Line 1 specifies the file
directory path where the capacitance values are saved. This file directory path must be the same as
the one used by the SaveCableCompCaps82 user module.
