Would you mind posting a quick hand-sketch schematic of the above? I'm trying to figure out what you mean by "matches my source's 50 ohm output".

I'm familiar with placing a reference resistance of known value in series with an inductor under test and finding the sinusoidal frequency at which the true RMS voltage drop across the coil equals the drop across the reference resistor, but that doesn't seem to be what you are describing.
