Abstract

The invention relates to the technical field of signal release, in particular to close-range electric field anti-interference test equipment, which comprises an umbrella-shaped antenna; the adjustable attenuator is connected between the power amplifier and the antenna and is used for adjusting the gain of an output signal of the power amplifier; the power amplifier is connected with the antenna and is used for amplifying a signal; the signal source is connected with the power amplifier and is used for releasing a radio frequency signal; the directional coupler is arranged between the power amplifier and the antenna and is used for coupling a signal to a power meter; the power meter is connected with the directional coupler and is used for detecting the intensity of a signal released by the antenna; and the adjusting system is respectively connected with the power amplifier, the signal source, the directional coupler and the power meter and is used for adjusting the working state of each component. According to the invention, by arranging the umbrella-shaped antenna, the blank of a near-distance electric field immunity testing method for the frequency band of 26-380 MHz in the prior art is filled.

Description

technical field [0001] The invention relates to the technical field of signal release, in particular to a short-range electric field anti-interference testing device. Background technique [0002] Radiated immunity testing is a test of the ability of electrical equipment, especially medical equipment, to conduct its immunity to radiation. In general, medical equipment and electrical equipment need to be tested with a homogeneous electromagnetic field. [0003] In the current radiation immunity test, it is generally necessary to use the far-field method to ensure that the emitted electromagnetic field is kept uniform in the far-field and within the uniform field within the frontal irradiation range of the antenna, that is, the field strength emitted by the antenna is within the field 4 In the square of meter * 4 meters, the difference of the field strength of 16 points is within ±4dB. [0004] The Chinese patent with the patent number CN206118297U discloses an electronic in...
