  • Patent number: 7020443
    Abstract: The invention relates to a method for measuring a radio frequency signal in a wireless station (1). In this method, radio frequency power is measured by means of testing equipment (6, 7, 12), which includes at least a testing apparatus (7), a measuring head (6) and means (12) for transmitting electrical signals between the testing apparatus (7) and measuring head (6). The wireless station (1) includes at least one radio part (8), a wiring board (2), an antenna (5) and switching means (3, 22). This test switch has at least an first position, in which the radio frequency signal is directed between the radio part (8) of the wireless station (1) and the antenna (5), and a second position, in which the radio frequency signal is directed between the radio part (8) of the wireless station (1) and the testing apparatus (7) via the switching means (3, 22) and the measuring head (6).
