Top Uses of Burst Tester and Generator for Quality Assurance

The burst generator is also called burst tester, is a kind of EMI filter, and its name comes from the “Electrical Fast Transient/burst” (abbreviated as EFT) experiment. The EFT experiment is an immunity test experiment, which is divided into four levels according to the IEC61000-4-4 standard. Different levels of EFT generators have different injection voltages or cargo coupling voltage...

EMC Testing Vs. EMI Testing: What’s Difference

The terms electromagnetic compatibility (EMC) and electromagnetic interference are often used interchangeably when talking about the testing of commercial electronic goods and products. Because the two types of tests share so many similarities, it’s very easy to confuse one with the other. In this article, we will attempt to highlight some of the major differences between EMC and EMI testing. We...

Maximizing EFT Protection with EFT Pulse Generators and EFT Surge Suppressors

The origin of the EFT pulse generator: In industrial process measurement and control devices, when the inductive load is disconnected, a transient pulse group (string) of several thousand volts will be generated at the breakpoint, and this disturbance will be conducted through the power line or signal line (some Radiation) enters the measurement and control device, causing the digital circuit o...

The importance of PCB board in EMC design

In addition to the selection and circuit design of components, good printing circuit board (PCB) design is also a very important factor in electromagnetic compatibility. The key to the design of PCB in EMC is to reduce the return area as much as possible and let the return path flow in the direction of the design. The most common return current comes from the cracks of the reference plane, the tra...

Countermeasures and Corrective Measures for Common Problems for EFT Immunity Measurement

1. The mechanism of EFT Immunity Measurement and its impact on electronic products The EFT immunity tester is a transient disturbance generated at the disconnection due to the insulation breakdown of the switch contact gap or the contact bounce when the inductive load (such as relay, contactor, etc.) is disconnected. When the inductive load is repeatedly switched on and off for many times, the pul...

How does EFT Immunity Testing help reduce the negative impact

An immunity test called EFT Immunity Measurement (EFT61000-4) is used to evaluate how well electrical and electronic equipment performs when subjected to interference. A device is put through a number of tests to see if it can withstand fast transients like electrostatic discharge and power line transients. Verifying the laboratory’s operating parameters, examining the EFT waveform, running ...
