You are purchasing (1) New. The MFJ-269D is a compact battery powered RF impedance analyzer. It combines five basic circuits; a variable oscillator, frequency counter, frequency multiplier, 50-ohm RF bridge, twelve-bit A-D converter, and a microcontroller. Together, these circuits perform a wide variety of useful antenna and RF impedance measurements including coaxial cable loss and electrical distance to an open or short. Although mainly designed for analyzing 50-ohm antenna and transmission line systems, the MFJ-269D also measures RF impedance from a few ohms to several hundred ohms.
An easy-to-access user controlled Zo setting in the Advanced function menus facilitates changing SWR and other SWR functions i. Return loss, reflection coefficient, match efficiency, etc to any normalized impedance value between 5 and 600 ohms. The MFJ-269D also functions as a non-precision signal source and frequency counter. Operating frequency extends from 0.10 to 230 MHz in nine overlapping bands with extended SWR measurement from 415 to 470 MHz.Typical Use of the The MFJ-269D may be used to adjust, test, or measure the following. Antennas: SWR, impedance, reactance, resistance, resonant frequency, and bandwidth. Antenna tuners: SWR, bandwidth, frequency.
Amplifiers: Input and output matching networks, chokes, suppressors, traps, and components. Coaxial transmission lines: SWR, length, velocity factor, approximate Q and loss, resonant frequency, and impedance.
Filters: SWR, attenuation, and frequency range. Matching or tuning stubs: SWR, approximate Q, resonant frequency, bandwidth, impedance. Traps: Resonant frequency and approximate Q.
Tuned Circuits: Resonant frequency and approximate Q. Small capacitors: Value and self-resonant frequency. RF chokes and inductors: Self-resonant frequency, series resonance, and value. The MFJ-269D measures and directly displays the following. Electrical length (feet or deg).
Impedance or Z magnitude (ohms). The MFJ-269D is also useful as a non-precision signal source.
It provides a relatively pure (harmonics better than -25 dBc) signal of approximately 3 Vpp (20 mW) into a 50 ohm load. The internal source impedance is 50 ohms. Although not "stabilized", it provides adequate stability for noncritical applications such as alignment of broad-bandwidth filters and circuits. 100-230, 415-470MHz, SWR Antenna Analyzer" is in sale since Friday, December 11, 2020.
