Ferroelectric Test System
Many engineers of Dexinmag Company have developed the Ferroelectric Analyzer for many years based on drawing lessons from the most advanced test methods in the world. It has more powerful test functions, the maximum test frequency of the equipment can reach 1MHz, and a high-speed sampling speed of 40M Spend. Some technical indicators exceed imported instruments, which is a real domestic independent innovation. At the same time, the measurement functions of the dielectric spectrum, electric card test, TSDC, resistance and other measurement functions have also been added. It can perform continuous and high-speed measurements under different measurement conditions and measurement modes, and only one Dexinmag ferroelectric instrument can replace the measurement functions of many instruments for functional material testing!

Instrument Configuration
Dexinmag FTS series ferroelectric test system is the most advanced equipment in the market, with a wide frequency response range and wide test voltage range, and its high test accuracy capability is second to none in the field of ferroelectric testing in the world. Under the built-in voltage of ±10V, the hysteresis loop test frequency can be as high as 500KHz; (the test index of this instrument has exceeded the imported equipment. For the extended high-voltage amplifier, the maximum test frequency of the hysteresis loop is related to the frequency of the external amplifier.) This system includes Dexinmag basic ferroelectric management test software. In addition, the voltage can be extended externally to 4kV, 10kV, and 20kV. The Dexinmag host can perform hysteresis loop, pulse, leakage current, IV, CV, and breakdown tests without changing the sample connection, and can also be loaded with options to achieve Piezoelectric, pyroelectric, TSDC and electric card, impedance analysis, resistance measurement and other characteristic test functions. Built-in complete dedicated industrial computer host, test circuit, operational amplifier, data processing unit, etc., including dedicated industrial computer motherboard, CPU (i5 or higher), RAM (8G or greater), solid state hard drive (250G or greater), network card, USB interface, DVD drive, VGA interface, pre-installed Windows 7 operating system, special test software for ferroelectric analyzer, etc.
