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
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
At present, electronic equipment is used in various electronic products and systems, and printed circuit boards are still the basic installation method. Practice has proved that even if the circuit de
Harmonics have damaged the public power grid to a certain extent and become one of the pollutants of the power grid. At present, various methods have certain defects. Therefore, analysis and research
In order to ensure the consistency of traceability, it is necessary to meet the different test conditions and standards of EMI in different laboratories. When you are uncertain, you must absolutely en
For the EMC immunity of testing equipment, the electrical fast transient burst test is of typical significance. Because the rising edge of the electric fast transient pulse group test waveform is very
The working frequency band of EMC test is very wide. Because we do not know the number of scratches in advance, the detection must rely on various detection antennas to convert the field strength into
Interference signals will damage other electronic equipment around to a certain extent. However, the same electronic equipment, general IT products and automotive electronic products do have different
With the increasing volume and power of switching power supply, EMI test operation has become a key factor in the reliability of switching power supply. EMI filtering technology, shielding technology,
Through circuit integration, modularization, circuit analysis and design, it can be said that it is a comprehensive analysis and design. The EMI scheme research will have a significant impact on the i
For many years, the effect of electromagnetic interference EMI test has been a matter of great concern in modern electronic control systems. Especially in today's automobile industry, cars use many cr
In the EMC test of electromagnetic compatibility radiation emission, the most common is the clock radiation exceeding the standard (as shown in the figure). It can be said that 70% of the excessive ra
