Details
This user module uses the 590 and 595 to perform simultaneous C-V measurements. The following
figure shows the default parameters for the SIMCVsweep82 user module.
It performs a staircase sweep from −3 V to +3 V in 20 mV steps, as shown in
description
You can make an offset correction measurement and use the cable compensation.
For details on quasistatic measurements, see
4200A-901-01 Rev. C / February 2017
Output; the measured array of high frequency capacitance values
This must be set to a value equal to the number of voltage steps in the sweep
or value = ((VSub_Stop − VSub_Start) / VSub_Step − 1)
Output; the array of bias voltages used
This must be set to a value equal to the number of voltage steps in the sweep
or value = ((VSub_Stop − VSub_Start) / VSub_Step − 1)
Output; the measured array of quasistatic capacitance values
This must be set to a value equal to the number of voltage steps in the sweep
or value = ((VSub_Stop − VSub_Start) / VSub_Step − 1)
Output; the array of measured conductance (G) or resistance (R) values
This must be set to a value equal to the number of voltage steps in the sweep
or value = ((VSub_Stop − VSub_Start) / VSub_Step − 1)
Output; the array of Q/T from 595 output for each measurement step
This must be set to a value equal to the number of voltage steps in the sweep
or value = ((VSub_Stop − VSub_Start) / VSub_Step − 1)
