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...
Purpose of Integrating Spheres An integrating sphere gathers electromagnetic radiation from a source that is typically external to the optical instrument. This is done for the purpose of flux measurement or optical attenuation. Radiation that is introduced into an integrating sphere lighting system hits the reflective walls and is diffusely reflected many times. The radiation is scattered highly u...
JL-X waterproof test machine is according to IEC60529:1989 +A1:1999 +A2：2013 《Degrees of protection provided by enclosures(IP Code)》, IEC60598, IEC60335 and IEC 60034-5, GB/T-2423.2, GB4208, GB7000.1. The JL-X includes the following test grades: IPX1, IPX2, IPX3, IPX4, IPX5, IPX6, IPX7 and IPX8 (Refer to page 51 of IEC60529). It is widely used in the authentication test organization fo...
Dust chambers are a particularly effective tool for this since they may test a product or component’s ability to resist dust. Dust test chambers offer a comprehensive analysis of how dust affects machinery under adverse conditions. All the models typically make sure that the dust particles only enter the testing environment. Hence, the blowing sand test chamber ensures usual workplace operat...
