  We investigate quantum-statistical correlation properties of a periodically
driven mesoscopic scatterer on a time-scale shorter than the period of a drive.
In this limit the intrinsic quantum fluctuations in the system of fermions are
the main source of a noise. Nevertheless the effect of a slow periodic drive is
clearly visible in a two-time current-current correlation function as a
specific periodic in time modulation. In the limit of a strong drive such a
modulation can change the sign of a current correlation function.
