ABSTRACT:
A method is disclosed for dynamically testing a radio system having output terminals connectable to a speaker system in a motor vehicle wherein the method utilizes a dynamometer, a transverse electromagnetic cell, a signal generator and a signal analyzer and includes the steps of placing the motor vehicle in the transverse electromagnetic cell, connecting the output terminals to the signal analyzer, operating the motor vehicle on the dynamometer inside the transverse electromagnetic cell, generating a signal using the signal generator, transmitting the signal from the signal generator to the transverse electromagnetic cell, emitting the signal onto the motor vehicle, and measuring an output signal generated by the radio system at the output terminals using the signal analyzer.
