AD5933EVM Purely capacitive impedance measurement issue

Hi,

I am trying to configure my AD5933 evaluation board. I am trying a purely capacitive circuit i.e trying to get response of the evaluation board for just measuring a capacitor. My impedance values are correct however, my phase response of the circuit for any sort of combination is just 0 degrees. I cannot seem to understand why is this happening? I have just connected a 10nF capacitor and I was trying to find the response for a range from 30KHz-50KHz.
