Abstract

In the present invention, set iron cage nets for containing object to be tested and its emitter and receiver at the test stations of production line and a distribance emitter with the same frequency with the emitted and carrier wave with no loaded signal is set between two iron cage nets. It is composed of frequency varying circuit, crystal osciollation and frequency regulation circuit, power regulation circuit, power output circuit and emission antenna which are connected in proper order. When they are tested, the electric wave radiated outside will be attenuated by the iron cage net and will be disturbed-damaged by the disturbance emitter, the disturbed-damaged electric wave will be again atlenuated by the iron cage net before it reaches another receiver and it will not be decoded by the receiver.

Description

technical field

[0001] The present invention relates to a test device and test method of short-wave FM digital radio under micro-power, especially a kind of test station which can set up two or more anti-interference on the production line at the same time, and an interference test station is set between the two test stations. Transmitter, so as to achieve the effect of preventing mutual interference between two adjacent test stations in an all-round way. Background technique

[0002] With the vigorous development of science and technology, the general products used by people have gradually undergone major innovations, and the future trend of science and technology is heading in the direction of wireless telecommunications. However, various micro-power short-wave FM digital radio When products are manufactured, most of them will encounter the problem of mutual interference, and traditional testing methods (such as figure 1 As shown), the purpose of the test is to use the me...
