Abstract
An electronic instrument is disclosed for measuring directional RF power levels and power function levels on a coaxial transmission line. The instrument includes an inductive sensing loop for sensing the RF voltage level on the transmission line and producing a voltage level proportional thereto. An analog-to-digital conversion means is connected to the sensing loop for converting the voltage level from the sensing loop to binary voltage data. A microcomputer means is associated with the conversion means for performing arithmetic operations upon the binary voltage data to calculate power data and power function data. Means connected to the microcomputer means are also provided for displaying the calculated power data and power function data. The instrument provides a direct readout in digital form of RF power data and data for various power and voltage functions such as VSWR.
