Brief Introduction

Friendly interface, easy operation and excellent performance

The instrument adopts a new generation AC/DC superposition test theory to adapt test requirements for high precision and high frequency.The built-in embedded MCU with high- performance can quickly respond to host and slave machine condition or malfunction and make real time indication, which helps improve the work efficiency.

The new designed friendly graphical operation interface, included 5 foot control modes and full touch operation provides convenience and efficiency for users. New file management system with easy, prompt and accurate operation can save a group of real-time setting file and 99 groups of user-defined setting files.

It can provide pushed information indication and cache 2 real-time information. Being provided with two modes of SCPI instruction systems, it is convenient to set up production lines or single machine test. Also, it can connects with any device with serial port and which refer to the SCPI instruction system design of this machine.

New Trend of AC/DC Superposition Test By virtue of profound technology and extensive market survey in bias current field, Tonghui introduced the large power DC bias current source— TH1778A. CortexM3 ARM CPU with high-performance, graphical interfaces and full-touch operation make TH1778A series DC Bias Current Source convenient and efficient for you.

TH1778A series is appropriate for AC/DC superposition test of magnetic inductors and test occasion for large current. Also, it can provide magnetizing current for the analysis of magnetic materials. The adopted new software framework is adapt to real-time parameter adjustment and operation.

New Trend of AC/DC Superposition Test

1 Master-Slave connection mode is convenient for cutting and extending.

2 Graphic interface brings unprecedented operation convenience and rapid response to working condition of the machine.

3 Pushed information indication can keep concurrent status information.

4 Intelligent file management system makes file management and load not complicated any longer.

5 Multi-mode SCPI system makes the formation of production lines not tedious any more.

6 Multiple operator modes makes it easier to operate on the basis of personal habits.

7 Cabinet type system connection makes it convenient for users to arrange and set up production lines.
