We are working with a AD5933 impedance converter and the corresponding evaluation board EVAL-AD5933EBZ, but even with the most simple circuit to mesure (for example a 100k resistance) we got values of impedance of 10E-5 ohms. We have also tried working with capacitors, changing the start frequency, the delta frequency and the number of increments, but it doesn't work. However, the phase seems to be correct.
We are calibrating with a 160k resistence. What could we be doing wrong?
