Electromagnetic compatibility testing is a testing method used to evaluate whether electronic devices can function properly in electromagnetic environments. When conducting EMC testing, multiple devices and instruments are required to ensure the accuracy and reliability of the testing. If you are interested in the upcoming content, please continue reading the following text, hoping it can be helpful to you.

1. Spectrum analyzer

Spectrum analyzer is an instrument used to measure the frequency and intensity of electromagnetic field, and is one of the important equipment for EMC testing. The Spectrum analyzer can measure the intensity of the radiated electromagnetic field of the equipment at different frequencies to evaluate the compatibility of the equipment. The accuracy and sensitivity of Spectrum analyzer are of great significance to the accuracy and reliability of test results.

2. Antenna

An antenna is a device used to receive and transmit electromagnetic waves, and is also one of the important equipment for EMC testing. Antennas can be used for radiation testing and conduction testing. By adjusting the direction and position of the antenna, the radiation electromagnetic field intensity of the equipment in different directions and positions can be measured. The frequency range and gain of the antenna are of great significance for the accuracy and reliability of test results.

3. Signal generator and power amplifier

Signal generators and power amplifiers are devices used to generate electromagnetic fields and can be used for conducting tests. A signal generator can generate signals of specific frequencies and amplitudes, while a power amplifier can amplify the power of the signal to generate sufficient electromagnetic field strength. The frequency range and output power of signal generators and power amplifiers are of great significance for the accuracy and reliability of test results.

4. Cables and filters

Cable and filter are devices used to connect and filter signals, which can be used for conducting tests. The cable can transmit signals from the signal generator to the input port of the tested device, while the filter can filter out unnecessary signals to ensure the accuracy and reliability of the test results. The frequency range and transmission loss of cables and filters are of great significance for the accuracy and reliability of test results.

When conducting EMC testing, it is necessary to select and adjust according to different devices and applications. The accuracy, sensitivity, frequency range, output power, and transmission loss parameters of these equipment and instruments are of great significance for the accuracy and reliability of test results.
