The Karlsruhe Institute of Technology and Bilfinger Noell jointly develop superconducting undulators for light sources. After the R&D phase the collaboration has completed the first worldwide superconducting undulator product. The full scale superconducting undulator with 20 mm period length (SCU20) was installed in the storage ring KARA in December 2017. Since January 2018 SCU20 is in operation serving as radiation source for the NANO beamline. We present here the commissioning of SCU20 with electron beam, as well as the first results of the spectral characterization.
