tokens: The Astronomical Validation activities were made possible thanks to the invaluable support of the local technical staff and the technical commissioning team. The authors thank Cees Bassa and Ramesh Karuppusamy for their important help in setting up the ROACH backend for pulsar observations. D. Perrodin thanks Gemma Janssen for providing WSRT timing residuals shown in Fig. 15 . F. Loi gratefully acknowledges the Sardinia Regional Government for financial support of her PhD scholarship (P.O.R. Sardegna F.S.E. Operational Programme of the Autonomous Region of Sardinia, European Social Fund 2007–2013 – Axis IV Human Resources, Objective l.3, Line of Activity l.3.1.). From 2012 to 2014, D. Perrodin was supported by the ERC Advanced Grant “LEAP”, Grant Agreement Number 227947 (PI M. Kramer), which also provided a 10-gigabit-ethernet switch and a storage cluster for SRT LEAP observations. M. Pilia was supported by the Sardinia Regional Government through the project “Development of a Software Tool for the Study of Pulsars from Radio to Gamma-rays using Multi-mission Data” (CRP-25476). A. Ridolfi and C. Tiburzi gratefully acknowledge support from the Max-Planck-Institut für Radioastronomie. C.Tiburzi also acknowledges support from the Universitaet Bielefeld. V. Vacca was supported by the DFG Forschengruppe 1254 “Magnetisation of Interstellar and Intergalactic Media: The Prospects of Low-Frequency Radio Observations”. The development of the SARDARA backend was funded by the Autonomous Region of Sardinia (RAS) using resources from the Regional Law 7/2007 “Promotion of the scientific research and technological innovation in Sardinia” in the context of the research project CRP-49231 (year 2011): “High resolution sampling of the Universe in the radio band: an unprecedented instrument to understand the fundamental laws of the nature”. The Sardinia Radio Telescope is funded by the Department of University and Research (MIUR), the Italian Space Agency (ASI), and the Autonomous Region of Sardinia (RAS). It is operated as national facility by the National Institute for Astrophysics (INAF).
