Functional Features

1. highly accurate

The auto-balanced bridge ensures higher frequency accuracy over a wider frequency range than ordinary LCR bridges! The following figure compares the accuracy difference between auto-balanced bridges and ordinary bridges in the frequency range of 0-10MHz, using Tonghui bridges as an example. Currently, Tonghui's auto-balanced bridges include TH2839 series, TH2838 series and TH2828 series.

1.  c) Impedance analysis software (equivalent circuit analysis software)

Different types of devices in real life can be equated into simple circuit models consisting of 3-4 devices. The Impedance Analyzer host computer provides 7 basic circuit models for the equivalence of these devices. The software also provides an auto-matching function, i.e., if the device under test is a black box, the software automatically matches the model that best matches it and calculates the parameters. You can compare the impedance fitting curves of the simulated equivalent circuit parameter values with the actual measured impedance curves, and you can also fit the model of your choice according to the parameters you input. The equivalent circuit model can be directly exported to a TXT file for users to save and use.
