In 2011 a 1.5 m long superconducting undulator with a period length of 15mm is scheduled to be installed in ANKA. This insertion device is planned to be the light source of the new beamline NANO for high resolution X-ray diffraction. The key specifications of the system are an undulator parameter K higher than 2 (for a magnetic gap of 5mm) and a phase error smaller than 3.5 degrees. In order to characterize the magnetic field properties of the superconducting coils local field measurements have been performed by moving a set of Hall probes on a sledge in a liquid helium bath. The results of these investigations are presented.
