The ELBE accelerator, an electron linac with superconducting cavities, is designed for a beam energy of 40 MeV, a cw current up to 1 mA and a maximum bunch charge of 77 pC. After acceleration, the electron beam will be used to generate a variety of electromagnetic radiation with different wavelength. Two FELs will deliver coherent infrared radiation, monochromatic x-rays will be produced by means of a channeling target and MeV photons with a bremsstrahlung target. Furthermore, converter targets for neutron and positron production will be installed. For the first commissioning tests, the injector with a thermionic gun, one cryomodule with two nine-cell cavities and a diagnostic beam-line were in operation. Energy and energy width were determined with a magnetic spectrometer. Transverse emittance measurements were carried out with a pepper-pot mask in the injector and with the quadrupole scan method for the accelerated beam. Bunch length was determined from the autocorrelation function of the coherent transition radiation with a Martin-Puplett interferometer. The results of these beam parameter measurements will be presented and evaluated
