TH1778AS High-Precision 0-120A DC Bias Current Source for 6-Machine Output with 25mA Step

Low Noise and High Accuracy: DC Bias Current Sources are designed to have low noise levels and high accuracy in current delivery. Low noise is essential to minimize interference and ensure accurate measurements, especially when testing sensitive devices or performing signal integrity analysis. High accuracy ensures reliable and consistent biasing conditions, enabling precise evaluation of device performance and characteristics.
Application in Testing and Characterization: The DC Bias Current Source finds extensive use in testing and characterization of electronic components, such as transistors, diodes, integrated circuits (ICs), and sensors. It enables the assessment of device behavior under specific biasing conditions, facilitating the measurement of parameters like gain, linearity, leakage current, and threshold voltage. Additionally, it is employed in the calibration of measurement equipment, ensuring accurate and traceable results.

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 userdefined 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 realtime 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.
