I'm having trouble with the AD5933. I'm interfacing the controller perfectly, but...
When i'm reading all the values from the sweep, i get a imaginary value for every frequency even though i should only get real values, when i'm measuring a 4k resistor (only real).
Here is some of the values.
Please notice that the impedance of fx ((2004^2)+(-3485^2))^0.5 = 4.02 kOhm, very close to the resistor value. But for my application i do need both the imag and real values, not the impedance.
Any idea what i do wrong?
Kindest regards Simon
