NIST Time and Frequency July 29-31, 2025 NIST Boulder

NIST Time and Frequency Division's annual seminar covers precision clocks and 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 3-day course is the most comprehensive available.
