The present invention relates to a signal source joint control circuit and an analog receiver testing system made therefrom. The present invention discloses a signal source joint control circuit, which comprises an operation display module, a microprocessor and an IEEE-488 bus interface adapter, wherein the operation display module and the IEEE-488 bus interface adapter are both connected with a data interface of the microprocessor. In addition, the present invention also discloses an analog receiver testing system for electromagnetic interference sensitivity, which is made from the signal source joint control circuit. In the present invention, a signal source, a combiner, an audio analyzer and the like are integrated into one case, and only two interfaces, i.e., output and input, are reserved. For a tested receiver, only two lines are required to be connected. Thus, connection becomes simpler. Through the arrangement of the signal source joint control circuit, not only one or more signal sources can be controlled at the same time, but also the signal source joint control circuit is connected with the IEEE-488 bus interface circuit so that remote operation can be realized.
