  • Apparatus for measuring an RF parameter
    Patent number: 5726566
    Abstract: In apparatus for measuring the output power an RF transmitter stage (34) connected to an antenna (44) via a quarter wavelength stripline (38), a manual probe (20) is applied connect the output of the transmitter stage to a power meter (24) and connect the output end of the stripline (38) to ground. Thus, RF signals which were passed to the antenna (44) are switched to the power meter (24). All the circuitry including the antenna (44) is mounted on a printed circuit board (60) disposed within a housing (14) which has an aperture (18) to enable the probe (20) to be inserted. By providing a suitable meter, parameters other than RF power can be measured.
