I am going crazy with this AD5933 chip. Now i am measuring the impedance of a complex circuit. A parallel RLC circuit.
I am confused in designing of rfb and rcal, i know to design the rfb,rcal for resistor alone,capacitor alone and inductor alone,rc,rl.
Here for rfb=rcal=100k,
Is this correct??
Is there any other formula to calculate both rfb and rcal for RLC circuit???
Now my set up is
Here i am sweeping the frequency from 10k to 100k and rfb=100k and rcal=100k
Now i am measuring R100K,C=33pF,L=2.3mH
But in inductor case L i used is 2.3mH which is out of range still i am getting perfect answer for Impedance.
So i am confused in RLC measurement range!!!!
