Cablecompensate82 User Module - Keithley 4200A-SCS Reference Manual

Appendix D: Using a Model 82 C-V System

CableCompensate82 user module

The CableCompensate82 routine performs 590 cable compensation using the capacitor values
stored in the specified cable compensation file. The resultant compensation values generated by the
compensation process are stored in the same file.
Usage

Details
This user module, shown below, is used to do cable compensation for the selected ranges and test
frequencies of the 590. For the input parameters shown in the figure, cable compensation for the 590
is done for the 2 pF, 20 pF, 200 pF, and 2 nF ranges and for both the 100 kHz and 1 MHz test
frequencies. The line 1 input parameter indicates the directory path where the user-input capacitor
source values are saved. These values are entered and saved using the
user module
User-entered parameters and returned outputs for this user module are explained in the user module
description.
