Abstract: A method and apparatus for testing mobile communication devices involve utilizing the device's frequency hopping capabilities to substantially reduce the time required to measure operational parameters of the device at a plurality of frequencies across the device's operational frequency band. Prior to conducting the multi-frequency test, a device tester defines a hopping list of test frequency channels and transmits the hopping list and command signals to the mobile communication device for testing a set of operational parameters of the device at all of the test frequencies. The mobile communication device then measures all of the parameters at all of the frequencies by repeatedly sequentially hopping through the test frequencies in accordance with the hopping list.

Abstract: In an antenna coupler (100) for testing mobile telephones (10), simple structure, which has a low coupling attenuation, is provided in that the antenna coupler (100) has the following features: a printed circuit board (1), on the upper side of which there is formed by a strip transmission line technique at least one antenna element (7,8); and a receiving element for a mobile telephone (10) secured to the upper side of the printed circuit board (1).
