Additionally known as the lightning surge immunity test, combination wave generator, surge current/surge voltage generator, and combined surge voltage and current generator, the LISUN SG61000-5 completely automatic surge generator has various names. It offers a uniform platform for testing how well different types of equipment’s internal connectors and power cables hold up to high-energy t...
At present, the problem of electromagnetic compatibility of electronic products has attracted more and more attention. Especially developed countries in the world have formed a complete electromagnetic compatibility system. At the same time, our country is also establishing an electromagnetic compatibility system. Therefore, the realization of EMI testing of products is a passport to enter the int...
Introduction An Environmental Chamber GDJS-015B is a sealed room where environmental parameters like temperature and humidity can be adjusted. Some chambers are also known for delivering salt spray into the chamber to imitate corrosion. Depending on the sort of product to be evaluated, the sizes of these chambers may vary significantly. LISUN has an environmental test chamber, also known as a clim...
Introduction An EMI receiver measures electromagnetic disturbances by employing traditional stepped scans or ultrafast FFT-based time domain scans. This is done during the construction of the receiver. Additionally, it works effectively as a signal and spectrum analyzer. Usage of EMI Receiver 1. EMI test receivers are devices designed to detect electromagnetic emissions rigorously to guarantee t...
Introduction to integrating sphere An integrating sphere, also called an Ulbricht sphere, is an optical component consisting of a hollow cylindrical cavity with a diffuse white reflecting coating on the interior and small holes for entrance and exit ports. A uniform scattering or diffusing impact is its relevant attribute. An integrating sphere system can conveniently measure luminous flux and rad...
A salt spray test or salt fog test is a corrosion method for checking the corrosion resistance of the materials and coatings of the surface. The materials to be tested are usually stones, ceramics, and polymers. The surface of these materials is coated. This is done to provide them with a degree of corrosion resistance. This procedure is an accelerated corrosion test because it produces a corros...
Environmental test equipment is the general name of all test chambers simulating natural climate environment. Representative products include salt spray test chamber, high and low temperature test chamber, constant temperature and humidity test chamber, UV aging test chamber, xenon lamp aging test chamber, ozone aging test chamber, oven, etc. The environmental test chamber is one of the necessar...
A light-scattering substance, such as barium sulfate, is used to make the sphere’s spherical inner surface and inner wall. The light beam (measurement light) entering the sphere is equally scattered by integrating sphere. The measuring light shines via an aperture in the center of the integrating sphere. The sample is put at this aperture to measure the light passing through the selection an...
In any high voltage and electrical noise system, ESD immunity is an important aspect of EMC and a key consideration in the selection of current isolation devices. ESD can penetrate the electrical isolation system It does not involve protective devices on printed circuit boards. The International Standard IEC 61000-4-2 specifies this system level immunity In the typical operation and application en...
