Anyone here with a working ARTA impedance measurement box ?

I'd like to verify resistances between various points of the jig to verify if my ARTA impedance jig is wired correctly.

Even better if you are in the Dallas area.

I can generate the correct response curves (shapewise, impedance peak at correct frequency)but the impedance values themselves are off, despite the correct reference resistor and calibration procedure.

Thanks
