AB  - PETRA III is a 6 GeV third generation synchrotron light source in Hamburg, Germany. The storage ring is operated with a typical beam current of 100 mA and is running in top-up mode. The beam delivered to PETRA III is accelerated by a fast cycling booster synchrotron (DESY II), extracted in a 203 m long beam transport line (E-Weg) and injected afterwards into PETRA III. In the framework of PETRA IV upgrade scenarios the potential for decreasing the extracted emittance from DESY II has been investigated which can be achieved by lowering the extraction energy to 5 GeV and increasing the focusing in DESY II. In addition measuring the emittance of the extracted beam from DESY II and the optics in the beam transport line can help to better understand and improve the injection efficiency of PETRA III. By changing the quadrupole strength and measuring the beam size downstream on a screen monitor in the E-Weg the emittance of DESY II and the Twiss functions at a quadrupole in the E-Weg have been determined. Measurements at different energies of DESY II will be shown and compared with calculations.
