2018 NIST Time and Frequency Seminar

NIST Time and Frequency Division's annual seminar covers clocks, oscillators, atomic frequency standards, rf and optical synchronization, optical oscillators, quantum information, optical cooling and heating; making precise frequency, time, phase-noise, and jitter measurements; and establishing measurement accuracy and traceability. This 4-day course is the most comprehensive available.
