Introduction When studying electrical signals, digital oscilloscopes are necessary. You need to be acquainted with the most important aspects of a digital oscilloscope if you want to get the most out of using one. In this section, we’ll take a more in-depth look at those three fundamentals, namely resolution, bandwidth, and sample rate. These factors have a significant impact on the oscillos...
Salt is a ubiquitous compound, which not only exists in the ocean, atmosphere, land surface, lakes and rivers, but also causes machinery or electronic products to be exposed. However, the impact of salt fog environment should not be underestimated, as it can accelerate the corrosion of metals, leading to the damage of electrical and electronic products. In order to investigate the corrosion resist...
Sand and dust testing, also known as sand and dust resistance test, is a destructive testing equipment that simulates the natural wind and sand climate on products. It is suitable for testing the sealing performance and reliability of product shells. After testing, the performance of the product can be evaluated to determine whether it meets the requirements, for use in product design, improvemen...
The scientific name of dustproof test chamber is sand and dust test chamber, dustproof test machine, and other various names, which is used for the product to carry out the IP dustproof test instrument. Its scope of use includes but is not limited to electrical appliances, lighting fixtures, instruments and meters, intelligent robots, video equipment, vacuum cleaners, sweepers and other products....
I.What is EMI? Electromagnetic interference is the “decline of equipment, transmission channel or system performance caused by electromagnetic crosstalk”. Electromagnetic crosstalk is only an electromagnetic phenomenon, i.e. an objective physical phenomenon, which may lead to the reduction or damage of equipment performance, but not necessarily the consequences. Electromagnetic interfe...
Introduction Light source characterization is a common use for integrating spheres because of their adaptability. They allow for the precise measurement of a wide range of optical characteristics such illumination uniformity, directional lightness, colorimetric qualities, and total radiant flux. This article illustrates the importance of integrating spheres and discusses its uses in characterizing...
Introduction Goniophotometry is an effective measuring method that is vital to the study of luminaire deterioration and aging. The light output, light dispersion, and energy efficiency of lighting systems may all degrade over time due to changes in their optical characteristics. By quantitatively measuring and analyzing the light distribution properties of luminaires, goniophotometric analysis ena...
Waterproof tester, also known as rain test boxes, rain testing machines, etc., is used to test the waterproof performance of appliances or appliances with rainproof functions. Suitable for testing whether electrical products, casings, and seals can ensure the good performance of equipment and components in rainy environments. LISUN waterproof tester manufacturer has strong independent research an...
The Waterproof Test System is mainly used for waterproof testing or sealing testing of complete electronic products or components. Using compressed air for testing is a non-destructive testing method that will not cause secondary damage to the product. The product can be subjected to tests such as water spraying, water immersion, etc. to simulate various humid and flood environments and verify wh...
