Back to listSensor detection
With the continuous development of science and technology, a large number of electronic devices are integrated in the small car space, such as electronic integrated systems such as navigator, car audio, reversing radar and airbags. These electronic devices may emit interference in different bands to the surroundings. Signal. For example, when driving under the high-voltage power line, the operation will be invalid due to the interference of the on-board electronic control circuit, which will affect the experience of drivers and passengers at least, and cause car crashes and fatal accidents at worst. Therefore, related tests of automotive electronics are playing an increasingly important role in ensuring the safety of automobiles.
