Model 4200A-SCS Parameter Analyzer Reference Manual

This user module is used to make a single, fixed-bias capacitance and conductance measurement.

The default parameters for the 590-cmeas UTM, which uses the Cmeas590 user module, are shown

in the figure below.

In general, the 590 is set to source 5 V for 2 seconds, then make a measurement, as shown in the

following figure.

4200A-901-01 Rev. C / February 2017

Enables or disables the analog filter:

Enable (can minimize the amount noise in the readings, but increases

measurement time): 1

The reading rate used to acquire the measurements (0 to 4); see Details

Output: The measured capacitance

Output: The bias voltage used

Parallel measurement model: G_or_R is the measured conductance

Series measurement model: G_or_R is the measured resistance
