Embodiment Construction

[0021] Below in conjunction with specific embodiment the present invention is described in further detail, figure 1 It is a flow chart of an embodiment of the present invention. The subject of this embodiment is an EMC-30 receiver with a test frequency range of 9 kHz to 1 GHz and multiple attenuation levels.

[0022] Step 1, determine the working performance parameters of the EMC-30 receiver. Working performance parameters are the most important working performance parameters of the equipment (such as bit error rate, signal-to-noise ratio, response voltage / current, etc.) and their allowable values. It needs to be specified by the purchaser and user according to the specific application. In this embodiment, the working performance parameter of the EMC-30 receiver is the intermediate frequency response voltage, and it is specified that the response amplitude does not change (the amplitude on the front panel indicates full deviation) as its anti-interference threshold value.

Abstract

The invention discloses a method for confirming anti-high RF interferece threshold of electronic information equipment, which acquires the response rule of the electronic information equipment under asmall signal and low field density environment through an experiment method to extrapolate the response condition under the high RF environment and confirms the anti- interferece threshold accordingto the performance parameter of the equipment. The invention can accurately confirm the anti-high RF interferece threshold under the condtion that the prior laboratory condition can not simulate the high RF environment, provides a method for the electromagnetic compatibility evaluation and the military standard of the corresponding country of the equipment, and has simple method and easy operation.

Description

technical field [0001] The invention belongs to the field of electromagnetic compatibility research, in particular to a method for determining the threshold value of anti-strong radio frequency interference for electronic information equipment. Background technique [0002] With the rapid development of electronics, electricity, computers, and control technologies, the electromagnetic environment faced by electronic information equipment on ships, submarines, or other large-scale weapon platforms has become more and more complex and harsh. In order to protect the normal operation of electronic information equipment and give full play to its performance, it is necessary to set limits for the electromagnetic environment in which it is located and to control the radiation field strength of the corresponding transmitter. The limits are closely related. [0003] Due to the constraints of strong radio frequency laboratory simulation technology and testing technology, it is almost...
