ABSTRACT:
A controlled environment radio test apparatus includes first and second chambers for receiving respective first and second radio devices therein. The chambers are sized in proportion to an operational frequency of the radio devices to be tested. A signal-carrying conductor is coupled to the first and second chambers to carry a radio signal therebetween. A signal control device is connected to the radio test apparatus and configured for adjustably introducing selected signal impairments into the radio signal in order to controllably impair the radio signal. An output coupler may be provided for monitoring the effect of the signal impairments on the radio signal. An input coupler may be provided for introducing one or more perturbing signals into the radio signal. The first chamber is adapted so that transmission control inputs can be provided to the first radio device and the second chamber is adapted so that reception monitoring outputs can be received from the second radio device. The first chamber may be further adapted so that auxiliary input and output signals are provided to and received from the first chamber.
