Standing Wave Ratio Measurement Instrument. Virgil G Leenerts US Pat. # 4110685, Aug. 29th 1978, Filed Nov. 1st 1976. Abstract: The output voltages produced by two directional couplers are applied to analog circuitry for generating a voltage that is directly proportional to return loss. An analog meter scale is calibrated to indicate return loss in decibels and/or VSWR directly. |
