Point-velocity of a turbulent flow

I am trying something in Fluent which has been bothering me for days.
I have a turbulent flow and some fixed monitoring points. If I plot the velocity as a function of flow time for any of those points I should expect random velocity right? However what I get is a smooth sinusoidal wave. I tried to reduce the time step because I thought maybe because it is time-averaged. I still get the same almost perfect sinusoidal wave.
Is it even possible to capture the velocity fluctuation with fluent or any other CFD programs? If yes, how should I do it? I am really desperate to know. Thanks in advance.
