Overview

MFJ 269 RF Analyzers

MFJ 269 RF analyzers combine five basic circuits: a variable oscillator, frequency counter, frequency multiplier, 50 ohm RF bridge, and a 12-bit A-D converter and microcontroller. They perform a wide variety of useful antenna and RF impedance measurements, including coaxial cable loss and electrical distance to an open or short. Primarily designed for analyzing 50 ohm antenna and transmission line systems, they measure RF impedance between a few ohms and several hundred ohms. An easily accessed, user-controlled Zo setting in the function menus allows for changing SWR and other SWR functions (i.e. return loss, reflection coefficient, match efficiency, etc.) to any normalized impedance value between 5 and 600 ohms. The MFJ 269 RF analyzers also function as a non-precision signal source and frequency counter. The operating frequency range of these units extends from 1.8 to 170 MHz in six overlapping bands plus it includes SWR measurements on 415-470 MHz. They require 10 AA size batteries for portable operation (sold separately).
