Comparison of differences between commonly used EMC experimental projects for automotive electronics and projects corresponding to military standards

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

Design comparison of active and passive EMI filters

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

EMC's six-step approach to rectification

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

How to solve the EMC problem of high-speed data connection in cars

EMI peak, quasi-peak, average value difference analysis

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

Influence of DUT impedance of spectrum analyzer and EMI measurement receiver on test value

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

The basic requirements and methods of electromagnetic compatibility design in the field of automotive electronic equipment

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

GTEM cell plays the role of antenna in RF radiation test

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

EMC design and countermeasures have three methods: dredging, blocking and treatment

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

What are the causes of non-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

The Key Link of Electrostatic Discharge Laboratory Testing the Change of Electronic Equipment Characteristics
