EASy is a portable, compact and complete system for microstrip sensor characterisation that uses the front-end readout Beetle chip developed for CERN/LHC experiments.

EASy is a plug-and-play educational system based on the Alibava System. All components needed to start measuring are assembled and prepared, including the microstrip sensor.

EASy allows for a quick and simple setup, ideal for student laboratory experiments. Furthermore, a practical exercise book is also included.
