The Photo Injector Test facility at DESY, Zeuthen site, (PITZ) has an aim to develop and optimize high brightness electron sources for Free Electron Lasers like FLASH and the European XFEL. The new laser system allows to produce trains of laser pulses with flat-top temporal profiles of about 20 ps FWHM and rise/fall time of about 2 ps had been commissioned at PITZ in late autumn 2008. Photo electrons emitted from the Cs2Te cathode are accelerated by a 1.6-cell L band RF gun cavity operated at 60 MV/m maximum accelerating gradient at the cathode. For measuring of transverse projected emittance the so called single slit scan technique is used at PITZ. This procedure will be discussed. Recent results on measured emittance of electron beam will be presented.
