ABSTRACT:
A VSWR meter circuit using a variable RF attenuator for use in an electronic instrument for detecting and measuring the forward and reflected RF voltage wave signals on a coaxial transmission line. The instrument is integral with a coaxial line section adapted to be electrically inserted in a tubular transmission line, the line section having an outer conductor with a coaxial center conductor therein. An inductive pick-up coil is mounted in the field surrounding the center conductor for rotation about an axis normal to the axis of the line section and is responsive to the voltage wave signal on the transmission line. A D'Arsonval meter movement is connected to the pick-up coil through a meter circuit designed so that the meter provides an indication of the level of either the forward voltage wave signal or the reflected wave signal depending on the orientation of the inductive pick-up coil.
