VSWR (Standing Wave Ratio) In a direct reading measuring instrument with a standing wave ratio scale calibrated by V (+ V.), the traveling wave output voltage is divided semi-fixedly and a feedback resistor is provided in series with the emitter. The configuration is such that the reflected wave output voltage is applied to the base of the transistor, and the reflected wave output voltage is applied to the collector of the transistor through a resistor, and the VSWR is applied between the collector and ground.
A direct-reading VSWR meter comprising a direct-reading DC ammeter and a variable resistor for direct-reading scale calibration.
