TH2840A Precision LCR Digital Bridge

■ TH2840 series LCR digital bridge is a new generation of technology adopted by Changzhou Tonghui Electronics.

A new generation of LCR digital bridges has been successfully developed with an innovative dual-CPU architecture,

Linux underlying system, 10.1-inch capacitive touch screen, Chinese and English operation interface, built-in enable

The new generation of technology, such as instructions and help, solves the problem of slow LCR test speed, single display, and the need for a new test.

I. Cumbersome operation and other defects.

The TH2840 series LCR digital bridge is designed for frequencies from 20Hz-500kHz/2MHz.

Compensates for the lack of high performance bridges in the 500kHz frequency range.

Thanks to a 10.1-inch capacitive touchscreen with a resolution of 1280*800, the

The TH2840 series LCR digital bridge utilizes a four-parameter display, all settings, and monitoring,

Sorting parameters, status, etc. can be displayed on the same screen, avoiding the tedious operation of frequent switching.

Make.

A.10.1-inch large screen with four measurement parameters for details at a glance

10.1-inch touch screen, 1280 * 800 resolution, Linux system, Chinese and English operating interface, support for keyboard, mouse, LAN interface, brings unparalleled operational convenience

Sex.

The large screen offers the added benefit of being able to place four test parameters and sorting parameters, sorting results, function selections, etc. on the same screen and never look crowded.

Crowding and clutter, at the same time can display four kinds of measurement parameters, four kinds of measurement parameters arbitrarily adjustable.

The ease of operation and completeness of the display are readily apparent when compared to earlier LCRs.

B. Up to 1800 times/second measurement speed

Thanks to the innovative dual-CPU design, where one CPU is responsible for test processing data and the other for displaying data, the TH2840 test speed is up to 1,800 times/second.

High test speeds can greatly improve efficiency in automated production lines.

For part of the need for real-time sampling to reflect the characteristics of the transient changes in the measured part, or to measure the corresponding time of the change process, the TH2840 series of 0.56ms measurement speed can be a perfect solution.

As in the following application, a bias voltage is loaded between two polar plates and the capacitance at both ends varies with the bias voltage.

Record the capacitance C0 when no bias is applied.

Conventional LCR digital bridges, due to test speed limitations, are unable to reach sampling rates of a few

Almost real-time acquisition, with TH2840 series dual CPU, can observe the change process and calculate in real time.

C.Superb Hardware Configuration

In addition to the dual CPU design, the TH2840 series also enhances other hardware configuration parameters:

1. AC test level is increased to 20Vrms/100mA, which can only be achieved by TH2838H, and the range is wider when testing C-V curve.

2. DC bias is ±40V/±100mA, which is the highest configuration of the same kind of products.

3. Standard with independent 2A DC bias current source, for inductance test within 2A current brings the gospel, support the external TH1778A series expansion to 120A.

4. DCR test level increased to 20V, test mH class and above inductors more quickly and stably accurate.

D. Improved sorting settings

G. 10-speed sorting and programmable HANDLER interface

The instrument provides 10 grades of sorting, which provides the customer with the possibility to grade the quality of the product How to configure the HANDLER interface when connecting to automation equipment

The TH2840 series of LCRs will be able to output the sorting results directly to the HANDLER interface. output, which has always been a problem for automation customers, the TH2840 series LCR will

etc. are fully visualized, making automated connections easier.

H.Intelligent firmware upgrade method

The instrument itself can be updated by upgrading the firmware without returning to the factory for function improvement, bug solution, function upgrade, and so on.

TH2840 series LCR digital bridge firmware upgrade is very intelligent, can be carried out through the system setup interface or file management interface, intelligent search instrument memory, external USB flash drive

Even LAN upgrade packages with automatic upgrades.
