TH2851 series impedance analyzer is a new generation of impedance tester successfully developed by Changzhou Tonghui Electronics using the current advanced automatic balance bridge principle, which is the latest level of domestic impedance tester.

TH2851 series impedance analyzer has completely overturned the complicated and cumbersome operation interface of traditional domestic instruments. Based on the Windows 10 operating system, it has realized a fully computerized operation interface, making the test smarter and easier.

The TH2851 series impedance analyzer has also completely surpassed the 120MHz frequency bottleneck of similar foreign instruments; it has solved the defects that similar foreign instruments can only analyze and cannot be tested separately; the Chinese and English operation interface also solves the embarrassment that foreign instruments have only English interfaces; Two interfaces for testing and analysis make testing easier.

Thanks to advanced automatic balance bridge technology, the basic accuracy of 0.08% can be guaranteed in the frequency range of 10Hz-130MHz.

The test speed as fast as 5ms and the impedance test range as high as 1GΩ can meet the measurement requirements of components and materials, which is particularly beneficial for the measurement of low loss (D) capacitors and high quality factor (Q) inductors. The four-terminal pair port configuration can effectively eliminate the influence of the electromagnetic coupling of the test line, and the lower limit of the low-impedance test capability is extended ten times downwards compared with the conventional five-terminal configuration instrument.

 

A. High precision

The application of automatic balance bridge technology can achieve ideal measurement accuracy in the impedance range of 10Hz-130MHz and 1mΩ-100M. The highest accuracy is 0.08%, which is much higher than the impedance analyzer of the RF reflection measurement method. The accuracy of the network analyzer.

 

B. High stability and high consistency

The figure below is the curve of measuring 100Ω resistance at speed 5, test frequency 1MHz, and it can be seen from the figure below that its track noise is ≦0.003% (≦±0.0015Ω)

D. 10.1 inches large screen, four measurement parameters, let the details at a glance

10.1 inches touch screen, 1280*800 resolution, Windows 10 system, Chinese and English operation interface, support keyboard, mouse, LAN, VGA/HDMI interface, which brings unparalleled operation convenience.

The big screen brings more advantages: all test parameters and sorting parameters, sorting results, function selection and other parameters can be placed on the same screen, and it does not look crowded and messy, and it can display four measurement parameters at the same time. The four measurement parameters can be adjusted arbitrarily. The buttons on the left of the screen can quickly select 8 sets of test parameters

F. Powerful analysis graphical interface

The maximum number of channels can display up to 4 curves. There are fourteen split-screen display methods for each channel and curve.

G. Equivalent circuit analysis test

In real life, different types of devices can be equivalent to simple three-parameter four models, four-parameter three models of impedance devices, the equivalent circuit analysis and test function provides 7 basic circuit models for equivalent these Device.

The impedance fitting curve of the simulated equivalent circuit parameter values can be compared with the actual measured impedance curve, and the parameters you input can be fitted according to the selected model.

The equivalent circuit model can be directly output as a TXT file for users to save and use.
