The first radiation from the cryogenic permanent magnet undulator (CPMU17) has been observed in December 2018 at the BESSY II storage ring at HZB, and since then this device has served as a light source for beamline commissioning. It is the first in-vacuum undulator installed at BESSY II, and a new in-vacuum APPLE undulator (IVUE32) is planned to be installed in near future. Thus, a detailed study of the interactions between such an in-vacuum device and the electron beam is required. Beam-based measurements using orbit-bump and tune-shift methods have been applied to estimate the vertical impedance of CPMU17. For CPMU17 the first results of broad-band impedance studies are presented.
