Abstract

The report contains the obtained results and analysis of measurements of 7 time intervals from app. 20 ns to app. 12 µs performed by 24 participants from EURAMET and GULFMET community between Dec 2019 and Nov 2021. The uncertainty of the reference values were evaluated at the level of 5 ps and 10 ps. The applied measurement schemes were compared and discussed. An extended analysis was performed to explain some observed small ambiguities and to avoid any doubts. Final conclusion was positive for all participants and additional comments and conclusions were addressed valuable for TF community.
