Surges are a concern for every circuit developer since they are key problems in electronics. These surges are known as impulses. Impulses have the distinct characteristics of high voltages, typically in the kV range, that remain for a brief period. The features of an impulse voltage can be characterized as a high or low fall time. These impulses are followed by a very high voltage increase time. A...

The EMI receiver is one of the most useful devices to be used in an EMC test chamber in an Electromagnetic Compatibility (EMC) laboratory or engineering facility. EMI problems are frequently encountered throughout the early phases of the product development cycle and measuring receivers of several types are employed to identify and rectify these issues. An EMI receiver is used to perform testing f...
What is goniophotometer definition? LISUN LSG-1890B/LSG-1800A goniophotometer is automatic goniophotometric instrument for luminous intensity distribution measurements with facility for rotating the light source. LISUN LSG-1890B/LSG-1800A uses a constant temperature detector, Japanese motor and German precision angle coder which keep the test results with high accuracy. It is for industrial labora...
What is the function of Environmental Chambers? Temperature, humidity, air pressure, light, and motion can affect the performance of a product. The environmental chamber can be used to observe the performance of a product under certain conditions. It also helps extend product lifetime and examine the aging process. High and Low Temperature Humidity Chamber It is meant to copy a given environment s...
What is an EMI receiver? Electronic noise that interferes with cable transmissions and decreases signal integrity is known as Electromagnetic Interference or an EMI receiver. Electromagnetic radiation sources, such as motors and machines, are common sources of EMI receiver. There are two types of EMI receivers. These are conducted interference and radiated interference. The connection of signals o...
EMI receivers are a very good tool for analyzing EMI spectrums. This article will investigate alternatives such as spectrum analyzers. We will see how LISUN’s EMI receiver fares in the market in terms of standard compliance. EMI receivers EMI receivers are data gathering instruments. These have high performance for analysis. EMI receivers are useful when transient signals or spurious emissi...
Electromagnetic interference is one of the most difficult problems to solve when producing an electronic device. It is also known as EMI. The influence of these inevitable interferences on the instrument’s performance need to be carefully monitored. This is done to comprehend and quantify the electromagnetic compatibility of the instrument under test. Efforts are made to lessen the impact of...
IEC Certified Dust Test Chambers Are Correct Dust Testers Introduction Dust is intrusive contamination that can influence electronics and some other forms of equipment or machinery to overheat and malfunction. The manufacturer can verify their devices can withstand dusty surroundings by becoming well-sealed or undisturbed through such contamination by using the dust tester provided by different Du...
