EMC (electromagnetic compatibility) includes two parts: EM (electromagnetic sensitivity) and EMI (electromagnetic interference). Usually we call solving the EMC problem. In fact, it is to solve the external radiation interference of electronic equipment, or how to prevent equipment and electronic components from being interfered by electromagnetic wave interference from the outside world. To learn...
Introduction: In electrostatic discharge (ESD) testing, electrostatic discharge (ESD) guns are used to determine how vulnerable electronic components and systems are to ESD. Protecting both people and machinery from the risks posed by ESD guns is of the utmost importance during ESD testing. Safe testing procedures, including the use of electrostatic discharge (ESD) guns, are discussed. Familiarize...
I. Definition of an integrating sphere: An integrating sphere is an empty, hollow cavity covered with a diffuse, white reflective coating, also known as a photopic ball or flux ball. There is one or more holes on the wall for entering light and for placing the light receiver. The inner wall of the integrating sphere should be a good spherical surface; usually the deviation from the ideal sphere is...
According to the National Market Supervision and Administration and National Standardization Technology Commission announced, the National Lighting Electrical Standardization Technical Committee Light Radiation Measurement Branch of the National Lighting Appliance Standardization Technical Committee is responsible for the implementation of and the National Lighting Electrical Standardization Techn...
Integrating sphere overview: 1. Integrating sphere testing is utilized to measure the optical parameters of a light source and its accessories in order to better understand and control the quality and performance of the light source. An integrating sphere is a miniature spherical optical environment which is lined with a reflective coating that has nearly ideal diffuse reflectance properties. Any...
Introduction: The reliable functioning of electronic equipment across industries relies heavily on electromagnetic interference testing. The growth of wireless technologies and the growing complexity of electronic systems have made it crucial to develop thorough and effective EMI testing procedures. Broadband EMI testing is made possible by the sophisticated features of today’s EMI test rece...
Introduction The material sciences, among others, have benefited greatly from the use of high precision spectroradiometer integrating sphere systems. These devices provide precise spectrum measurements, allowing for in-depth analysis of materials’ optical characteristics. Material characterization, quality control, and the furtherance of research and development are just few of the many area...
I.Basic knowledge of EMI receiver EMI receiver, also known as Electromagnetic Interference Measurement Instrument, is the most widely used and basic measuring instrument in electromagnetic compatibility test. It is essentially a tuned measuring instrument which can selectively identify the pre-set frequency components from the interference signals received from the sensors, and display and record ...
The process of collecting data from a distant location utilizing a variety of sensing equipment, such as portable spectrophotometers, is referred to as remote sensing. This is a technique that has been around for quite some time. Applications that need distant sensing are increasingly turning to make use of portable spectrophotometers as a consequence of their mobility as well as their high level ...
