         Schlumberger/Solartron 1260                Agilent  E4991A

We have been equipped with the Broad-Band impedance analyzers for broad-band dielectric spectroscopy study of ferroelectric single crystal. The broad-band dielectric instrument includes two components-Schlumberger/Solartron 1260 and Agilent E4991A. Schlumberger 1260 has a test range from one-Micro-Hz to ten-Mega-Hz. Agilent E4991A has a test range from one-Mega-Hz to one-Giga-Hz. Thus, we could investigate materials using the powerful tool of dielectric spectroscopy from micro Hz to giga Hz.

HP 4192A  impedance  analyzer (1Hz-100MHz)

The equipment is very useful for common study of the dielectric properties of ferroelectric materials. It could characterize relatively fast (sweeping mode) the dielectric property in a appropriate frequency range.

Agilent 4285A impedance analyzer (75k-3M Hz)

The analyzer is used to fast determine the resonance-anti resonance property of piezoelectric single crystal  resonators for length mode, thickness mode, transverse mode and shear mode.

The 24 channel fast dielectric measurement system is lab-built using Tonghui electric-bridge. The system could determine the phase transition characteristics of 24 ferroelectric samples simultaneously in a temperature range of 25 to 100 centigrade.

The system is lab-built using Tonghui electric-bridge specially for the study of ferroelectric single crystal properties under dc bias of more than 500V and in a temperature range from 25 to 300 centigrade.

The ZJ-3A Berlincourt-type quasi-static d33 meter was purchased from Institute of Acoustics, Chinese Academy of Sciences for a fast piezoelectric measurement.

The pyroelectric measurement system was lab-built using Schlumberger voltage meter and mainly used to determine the pyroelectric performance from 25 to 150 centigrade.
