TonghuiPrecision LCR digital bridge TH2838Overview

TH2838/TH2838H/TH2838A supports high-power testing conditions with 20V AC test signals and 40V DC bias, and enhanced multi parameter list scanning/multi parameter graphical analysis capabilities will be beneficial for users to expand their component evaluation capabilities. TH2838/TH2838H/TH2838A is a powerful tool for electronic component design, inspection, quality control, and production testing. Its excellent performance and functionality provide powerful tools for the design and development of circuits, as well as the research and development of materials (electronic and non electronic). TH2838/TH2838H/TH2838A can achieve various tests such as IEC and MIL standards due to its performance.

high precision

Compared with ordinary LCR bridges, the automatic balancing bridge can ensure higher frequency accuracy over a wider frequency range! The following figure takes the Tonghui bridge as an example to compare the accuracy difference between the automatic balancing bridge and the ordinary bridge in the frequency range of 0-10MHz. At present, Tonghui's automatic balancing bridges include TH2839 series, TH2838 series, and TH2828 series.

Material dielectric constant test

The TH2838 series, together with the specialized material testing fixture TH26077 and the upper computer software, can conveniently and * * measure the dielectric constant of materials at different frequencies.

Impedance analysis software (equivalent circuit analysis software)

In real life, different types of devices can be equivalent to a simple circuit model consisting of 3-4 devices. The upper computer of the impedance analyzer provides 7 basic circuit models for equivalent devices. This software also provides automatic matching function, which means that if the tested part is a black box, the software automatically matches the model that matches it and calculates the parameters. You can compare the impedance fitting curve of the simulated equivalent circuit parameter values with the actual measured impedance curve, or fit it according to the model you choose based on the parameters you input. The equivalent circuit model of this function can be directly output as a TXT document for users to save and use.
