Abstract

The invention discloses a system for testing electronic magnetic interference susceptibility of an analog receiver. The system at least comprises a signal source I and a signal source II generating analog modulation signals, a signal source joint control circuit, a combiner, and an audio analyzer. The signal source I, the signal source II, the signal source joint control circuit and the audio analyzer are respectively connected with an IEEE-488 bus interface circuit connected with a computer. The signal source joint control circuit is connected with the signal source I and the signal source II. Both the signal source I and the signal source II are connected with the combiner. According to the system, the signal sources, the combiner, the audio analyzer and so on are integrated in one case, and only an input interface and an output interface are maintained, so that the tested receiver only needs to connect with two lines, and the connection becomes simpler. The signal source joint control circuit not only can control one or more signal sources at the same time, but also is connected with the IEEE-488 bus interface circuit, so that remote operation can be realized.

Description

technical field [0001] The invention relates to a radio system electromagnetic interference susceptibility testing system, in particular to a method and system for testing the electromagnetic interference susceptibility of an analog receiver. Background technique [0002] With the development of wireless communication technology, the application of wireless communication equipment has greatly facilitated people's production and life, but there are many types and models of wireless communication equipment, and the ensuing phenomenon of EMI (Electronic Magnetic Interference) It is also becoming more and more serious, and presents the characteristics of multiple frequency equipment, wide coverage frequency, and serious frequency overlap and overlap. It is very easy for electromagnetic interference between systems to occur, and even cause communication interruption and system failure, seriously affecting the overall performance of the radio system. Therefore, it is of great sign...
