The standards commonly used in China's automotive electronic EMC routine testing are shown in Table 1. GJB 151B-2013 integrates the contents of GJB 151A-97 and GJB 152A-97, and adds and modifies some
Active EMI filtering theory is a relatively new EMI filtering method, which can weaken the interference signal, enable engineers to greatly reduce the size of passive filters, control costs, and impro
Electromagnetic compatibility (EMC) refers to the unbearable interference signal capability caused by any equipment in the wrong environment when the equipment or system operates according to regulati
EMI Receiver can perform quasi-peak measurement, peak measurement and average measurement. In the EMI peak, quasi-peak and average difference analysis, when the input signal is a sine wave, the readin
The default unit of the spectrum analyzer is dBm, which is the power level value; EMI measurement receiver default unit dB μ 5. Is the voltage level. Why use different units of measurement? In additio
In order to ensure that electronic products will not affect other equipment in the complex electromagnetic environment, and will not be affected by other equipment, it is necessary to carry out strict
The anechoic chamber, as a test environment that replaces the outdoor wide field, has been widely used because of its sound characteristics. However, due to the high cost and expensive equipment that
Most applications of the equipment meet the requirements of standard EMC, with only one exception for non-standard EMC. Therefore, it is non-standard. EMC can be regarded as a part of the standard EMC
Electromagnetic compatibility (EMC) is an index to test the characteristics of equipment or system in the electromagnetic environment. The EMC level of electronic products needs to pass a series of st
Electrostatic discharge will seriously affect the difference of patients in clinical application, and even damage medical machinery. Therefore, the anti-interference (ESD) test of electrostatic discha
EMC is one of the key indicators of quality and safety certification, mainly through the comprehensive evaluation of electromagnetic impact and anti-interference of products. Many products will face t
