The Photo Injector Test facility in Zeuthen site (PITZ), DESY, is testing and optimizing high brightness electron sources for free electron lasers. A key issue for such studies is the accurate determination of the beam emittance using a dedicated setup. The tomography module at PITZ aims in reconstructing the phase space distribution of the electron beam from captured projections of the beam when rotated in the phase space. This diagnostic technique can resolve the two transverse planes simultaneously with an improved resolution for short pulse trains. After the successful installation and commissioning of the tomography module, the collected data allowed phase space measurements which will be presented together with simulation results. The comparison between the two highlights the difficulties rising from the strong impact of space-charge force, due to the specific features of the electron beam: very low emittance, high charge density and moderate energy. Future improvements of the setup are discussed finally.
