Abstract
An attenuation apparatus and a test system. The attenuation apparatus includes a signal transmission channel and at least one radiation loss structure, wherein the signal transmission channel is configured to perform transmission attenuation on the energy of a transmitted signal; the radiation loss structure is arranged in the signal transmission channel; the radiation loss structure has a first operating state and a second operating state; when the radiation loss structure is in the first operating state, the radiation loss structure is configured to perform radiation attenuation on the energy of a signal transmitted by the signal transmission channel; and when the radiation loss structure is in the second operating state, the radiation loss structure is configured to perform transmission attenuation on the energy of the signal transmitted by the signal transmission channel.
