Electronic equipment shall comply with relevant EMC test specifications. Only through EMC testing can we enter the market, customers can use it easily, reduce accidents caused by interference signals,
S485 is used for communication between equipment and computer or other equipment. In product application, its multi-wire, power supply, power signal, etc. are mixed together, and there is a potential
Various control technologies are usually used for EMC design. In general, the closer to the EMI source, the lower the cost of achieving EM control. PCB integrated circuit chip is EMI. Therefore, if we
Electromagnetic interference (EMI) is a part of our life. With the passage of time, a large number of radiation sources of intentional and unintentional EMI will cause serious damage to the circuit. T
Everyone knows that EMC describes the performance of products, namely, electromagnetic emission/interference EMI and electromagnetic immunity EMS. EMI also includes conduction and radiation; EMS also
Nowadays, with the rapid development of power electronics technology, there are more and more types of power loads, especially the motor system driven by frequency converter, which is used more and mo
This paper combines the electrical fast transient pulse group anti-interference test system and medical electronic equipment, establishes the pulse group anti-interference test model according to the
The radiation immunity room is an ideal fully sealed EMI test environment for conducting space, because it can completely control the frequency, direction and wavelength of the electromagnetic field g
Semi-anechoic chamber is also called electromagnetic compatibility anechoic chamber. The semi-anechoic chamber is similar to the full-anechoic chamber, and is also a six-sided box with shielding desig
Small size and low cost high-speed serial (HSS) interface is particularly valuable for mobile devices with small size, low power consumption and light weight. Electromagnetic interference (EMI) occurs
In the field of electromagnetic compatibility, there are two forms when voltage and current changes are transmitted through wires. One is that two wires are used as round-trip lines, which we call &qu
Lightning in summer is easy to damage electrical and electronic equipment, so many projects will use varistors to protect equipment and electronic components. Due to its advantages of fast response ti
