TH2851 series of Tonghui Precision Impedance AnalyzerProduct Details

TH2851 series of Tonghui Precision Impedance AnalyzerOverview

The TH2851 series impedance analyzer has also surpassed the 120MHz frequency bottleneck of similar foreign instruments; Solved the defect of similar foreign instruments that can only analyze and cannot be tested separately; The Chinese English interface also solves the embarrassment of foreign instruments having only an English interface; Adopting both single test and analysis interfaces makes testing easier. The testing speed of up to 2.5ms and impedance testing range of up to 100M Ω of Kuaida 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 port configuration method can effectively eliminate the influence of electromagnetic coupling on the test line, and expand the lower limit of low impedance testing capability ten times lower than that of conventional five terminal configuration instruments.

high precision

The application of broadband automatic zeroing type automatic balancing bridge technology can achieve an ideal measurement accuracy of 10% in the impedance range of 10Hz-130MHz and 25m Ω -40M Ω, with a high accuracy of 0.08%, far higher than the accuracy of impedance analyzers and network analyzers using RF reflection measurement method.

High stability and consistency

The following figure shows the curve of measuring a 100 Ω resistance at a speed of 5 and a test frequency of 1MHz. It can be seen from the figure that the trajectory noise is ≤ 0.003% (≤± 0.0015 Ω)

10.1-inch large screen with four measurement parameters, allowing for a clear view of details

10.1-inch touch screen, 1280 * 800 resolution, Windows 10 system, Chinese and English operating interface, supporting keyboard, mouse, LAN, VGA/HDMI interfaces, bringing unparalleled operational convenience. The advantage of a large screen is that all test parameters, sorting parameters, sorting results, function selections, and other parameters can be placed on the same screen without appearing crowded or cluttered. At the same time, it can display four measurement parameters, which can be adjusted arbitrarily. The button on the left side of the screen allows for quick selection of 8 sets of test parameters

Segmented scanning function

Segmented scanning is a scanning process that sets different frequency segments within a scanning cycle. Different levels and biases can be set during scanning, and the scanning results are directly displayed graphically. It is used for scanning requirements that require quick filtering of multiple frequency segment parameters. If the crystal resonator needs to test the nominal resonant/anti resonant frequency and other stray frequencies, the segmented scanning function can be used to scan and measure within a specific frequency range without scanning unrelated frequencies.

Equivalent Circuit Analysis Test

In real life, different types of devices can be equivalent to simple impedance devices with three parameters and four models, and four parameters and three models. The equivalent circuit analysis and testing function provides seven basic circuit models for equivalent these devices. The impedance fitting curve of the simulated equivalent circuit parameter values can be compared with the actual measured impedance curve, and the selected model can also be fitted based on the parameters you input. The equivalent circuit model can be directly output as a TXT document for users to save and use
