ABSTRACT:
A swept-frequency VSWR measurement system for slotted lines is disclosed in which the measurement values are rapidly produced as a graph of VSWR versus frequency over a range of 2-18 GHz, in which the VSWR is given directly by the height of the ordinate at any frequency without requiring subtraction of two values derived from graph measurements as previously done. In addition, a "slope" correction is continuously made for errors introduced by physical imperfections of the slotted line, simultaneously with the taking of the swept frequency measurement.
