1、 Basic Overview

A ferroelectric analyzer is a testing device used to measure the electrical characteristic parameters of electronic materials such as ferroelectricity, piezoelectricity, and pyroelectric.

2、 Working principle

A ferroelectric analyzer applies a controllable electric field to a material and measures its polarization response to obtain electrical performance parameters of the material. The workflow mainly includes steps such as electric field application, polarization measurement, polarization curve recording, impedance gain measurement, frequency selection, voltage control, and data processing.

3、 Main components

The basic components of a ferroelectric analyzer include the following:

Basic Unit and FE Standard Module: Provides basic testing functions and standard testing methods.
