Troubleshooting MFJ-259B & Homebrew QRP Dummy Load ... •MFJ 259: “Resistance” reading should equal R regardless of X •The MFJ 259B “Impedance” meter displays Z as one number R R L C X Physical Circuit Equivalent Impedance Circuit Impedance At any specified frequency (F) X = j2pFL + 1/(j2pFC) = j2pFL – j[1/(2pFC)] MFJ 259B HF/VHF SWR analyzers are compact, battery-powered RF impedance analyzers. They combine four basic circuits; a 1.8-170 MHz variable frequency oscillator, a frequency counter, a 50 ohm RF bridge, and an 8-bit micro-controller. The analyzers make a wide variety of useful antenna or impedance measurements, including coaxial cable loss and distance to an open or short. Primarily designed ... The first method involves placing a 50 ohm resistor in series with the MFJ-259 "ANTENNA"... Page 16: Testing Rf Chokes This magnetically couples the MFJ-259 to the resonant circuit. The frequency of the MFJ-259 is adjusted for a dip on the "SWR" meter.
