摘要
A method for testing micropower short-wave frequency-modulation digital radio includes the steps of providing at each test station on a production line with a steel cage that is adapted to accommodate a transmitter and a corresponding receiver for test; and providing between two steel cages located at two adjacent test stations with an interference generator that transmits signal-free carriers having the same frequency as that of electric waves transmitted from the transmitter to be tested. Electric waves outward radiated from a steel cage are first attenuated by the steel cage, then destructed by electric waves from the interference generator, and then attenuated again by a steel cage at another test station. Since the attenuated signal-free carriers are not decoded at the receiver in any other steel cage, radio tests could be simultaneously conducted at two adjacent test stations without being mutually interfered.
