PURPOSE:To easily realize a radio-wave propagation test inside a production line by a method wherein an antenna for test use and a communication apparatus under test are installed in a mobile radio-wave darkroom and their connection to a measuring instrument is changed over reasonably. CONSTITUTION:The loading and unloading mechanism of an antenna 12 for test use and of a communication apparatus 13 under test as an object under test is installed in a mobile radio-wave darkroom 1; a measuring system is constituted reasonably of the following: a transmission and reception changeover device 4 between the communication apparatus 13 under test as the object under test and measuring instruments 5, 6; its controller 7; and a level correction device 8. Thereby, a radio-wave propagation test is realized. |
