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.
