In case a product fails the EMC tests, the engineers are not only faced with a problem of identifying the failure, but also finding answers to the question of why the failure has occurred and how to correct the failure and ensure that it minimally fails. Electronic networks in the modern world have switching converters, oscillators, microcontrollers, wireless modules, and cables that create comple...
Ingress protection test is one of the significant quality assurance measures of present day electrical and mechanical products. An IP test machine enables the engineers to test the resistance to solid particles and moisture of a product based on international IP rating. The accuracy of the performance will be dependent on the machine set up and appropriate testing procedure transferring to the inv...
The reliability and stability of the modern materials, electronics, and other consumer products is tested on the controlled environment in which temperature and humidity can be manipulated with precision. Such is the reason that temperature humidity chambers are commonly used in the industries where the stability tests are needed with the high degree of accuracy. Temperature humidity chambers prov...
Lighting products are more complicated than ever due to the fast-growing use of LED lighting, intelligent luminaires, and sophisticated control systems. Such systems contain microcontrollers, drivers, communication modules, touch interfaces, and power electronics which are very sensitive to electrostatic discharge. Due to that fact, ESD simulator guns are considered to be the basic equipment that ...
The calibration of an EMI analyzer happens to be one of the most significant processes in electromagnetic compatibility laboratories and particularly, high sensitivity EMC, where even the slightest error in measurements influences the compliance determination. Engineers use accurate measurements to determine the level of interference, source of emission and to determine the performance of a produ...
1 Introduction In power transmission and electronic equipment applications, the flame retardancy of wires and cables is a key barrier to preventing fire accidents. If the flame retardancy of cables is not up to standard, once a short circuit, overload, or aging occurs, it is likely to cause flame spread, release toxic smoke and high-temperature droplets, resulting in serious casualties and propert...
The need to obtain an electromagnetic compatibility has now become a fundamental need in virtually all electronic devices, and such need has also made the need to have an accurate EMI test receiver system very pertinent. The current EMC testing systems use special receivers to identify, measure and process undesired electromagnetic disturbances. These are disturbances which are not always noticeab...
1. Introduction With the rapid iteration of the electronic information industry, the complexity and integration of electronic products continue to improve, placing more stringent requirements on core indicators such as accuracy, bandwidth, and sampling rate of electrical signal measurement instruments. As a key device that converts analog electrical signals into digital signals for processing and ...
1. Introduction In scenarios such as electronic equipment R&D, military classified system testing, and precision instrument calibration, low-frequency magnetic field interference (typically referring to magnetic fields below 30Hz) can seriously affect equipment performance and test accuracy. For example, when an oscilloscope measures weak electrical signals, external low-frequency magnetic fie...
