From what I can determine from the MFJ schematics, the MFJ259/269 seem to
make complex impedance measurements by performing mathematical calculations
on 4 AC voltages in a Wheatstone bridge circuit. I remember seeing an
article once describing how this works. Can anyone point me to a description
of the math involved?

I described it in RadCom a year or three ago - at least as far as the
vector diagrams, but not the detailed math.
