I have a P type inductor and I'm attempting to chart its impedance and inductance at freq. between 1KHz to 10KHz. I was using a PC based software and some simple hardware but now I got a hold of an AD5933 evaluation board from Analog Devices (this is some kind of a network analyzer), they call it an impedance converter. I am calibrating it using a 1KOhm 0.1% resistor and do the scan while I assure that feedback does not saturate the ADC.
This is the impedance chart (looks nice):
I find the reactive part using |Z| x sin(phase) and solve L = Xl / 2pif
Here is the chart:
And off course phase:
X axis is freq. in all charts, Y axis is Ohm on the 1st chart & Henry on the 2nd & degrees on the 3rd. This seems a little odd to me. The trend is visible, however the behavior is VERY non linear. What do you think?
