[How to connect ZEDBOARD XADC to external analog input?]

Hi,

I have a ZEDBOARD which I want to interface it to an analog input signal and see the sinusoidal output. i'm following lab 3 tutorial by Adam Taylor.

So, as for the first step, I tried to connect the signal generator to Vn and Vp. I expected to see the sinusoidal shape of the voltage in XADC dashboard (XADC wizard demo). and also set the ENABLE_ALL_AUXILIARY_CHANNELS check mark, which will include Vp/Vn. 

 I set the function generator to frq 50Hz and amplitude 400-600 vpp, or DC also I applied and checked the signal on the dashboard and serial oscilloscope both. But, the board produces no reaction and the Vp_Vn channel still gives an uneven sine wave or i guess its noise or something else. I tried so many times but still i'm stuck at this point . 

Could anyone suggest any solution or PoW ?
