Comprehensive electromagnetic compatibility and radio frequency testing equipment

Abstract

An omnidirectional electromagnetic compatibility and radio frequency (EMF) testing device is provided, which mainly includes an antenna frame, an automatic angle adjustment device, and a test antenna. The automatic angle adjustment device includes an input device, a distance measuring device, an encoder, a motor driver, a microcontroller, and a motor. The omnidirectional EMF testing device provided by this invention mainly inputs the test distance and the height of the electronic device under test (EUT) through the input device. After measuring and obtaining the real-time height of the test antenna using the distance measuring device, the encoder calculates the target angle. Then, the motor driver drives the test antenna to move and rotate to the target angle, so that the test antenna is aligned with the EUT in the azimuth and elevation directions, thereby achieving the purpose of rapid testing and improving test accuracy.
