Electronic equipment radio frequency electromagnetic field radiation immunity testing device and use method

Abstract

The invention relates to the technical field of electronic equipment, in particular to an electronic equipment radio frequency electromagnetic field radiation immunity testing device and a using method, the electronic equipment radio frequency electromagnetic field radiation immunity testing device comprises a shell, one end of the shell is slidably connected with a box body, and one side of the shell is provided with a first outlet. According to the device, the wave absorbing plate is coated with gum and clamped into the L-shaped clamping groove, the extraction mechanism at the first outlet is connected with the driving mechanism and keeps a certain distance from the wall surface, then the shell is pushed, the box body is made to move towards the shell through the moving mechanism, and the driving mechanism is started; the pulling-out mechanism at the first outlet pulls the wave-absorbing plate out of the first outlet to be attached to the wall surface, after all the wave-absorbing plates on the wall surface are attached, the pulling-out mechanism in the second outlet is connected with the driving mechanism, the driving mechanism is started, and the pulling-out mechanism at the second outlet pulls the wave-absorbing plate out of the second outlet to be attached to the ceiling. Therefore, a user can quickly arrange a proper anechoic chamber to carry out a radio frequency electromagnetic field radiation immunity test.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an electronic equipment radio frequency electromagnetic field radiation immunity test device and a use method. Background technique [0002] When electronic equipment is tested for immunity to radio frequency electromagnetic field radiation, it is necessary to use power amplifiers, field strength probes, antennas and other equipment. There are also certain requirements for the site, and the test needs to be carried out in an anechoic chamber. The anechoic chamber needs to have a suitable size, and at the same time In order to ensure the contrast and repeatability of the test results, the uniformity of the test site should be calibrated to maintain a uniform field with sufficient space relative to the EUT, and some absorbing materials should be installed locally to weaken the indoor reflection. When the layout changes (such as the movement of the test position or the ...

AI Technical Summary

Problems solved by technology

When the layout changes (such as the movement of the test position or the change of the test equipment), the calibration must be re-arranged, and the anechoic chamber must be re-arranged. It is difficult to arrange, and, for some experimental objects, more absorbing materials need to be laid, and it is difficult for testers to quickly complete the layout of the anechoic chamber when there are fewer testers.
