Imitation of test stand and ensure electromagnetic compatibility of radio communication equipment on mobile objects

摘要

1. Simulation test stand and to ensure electromagnetic compatibility of radio communication in a mobile object, consisting of a high-frequency generator of standard signals serially connected test radio receiver and total harmonic distortion analyzer, as well as the test of the radio transmission device, which is loaded by the equivalent of the antenna, characterized in that in it additionally introduced adjustment high attenuator having an input coupled to an output of the antenna equivalent simulator contact hydrochloric interference, control and security device of the electromagnetic compatibility and matching device, wherein the standard signal generator output is connected to the first input of the matching device, yield a regulated high frequency attenuator is connected to the second input of the matching device, a first output matching device connected to the input of the test radio receiving device, the second output matching device connected to the input control and to ensure EMC the device, and input them Tatorey contact interference connected to the third output matching unit, wherein the simulator contact interference is made in the form of two metal sheets arranged in parallel to each other and having intermittent contact with each other, one of the metal sheets is grounded, another metal sheet is mounted a source of vibration, such as an electric motor, and it is supplied with a high frequency voltage of the third output matching unit, control and to ensure electromagnetic compatibility device is
