37th NIST TF Seminar


















































































37th Annual Time and Frequency
Metrology Seminar

June 5-8, 2012
National Institute of Standards and Technology
Boulder, CO

The Time and Frequency Division of the National Institute of Standards and Technology is offering a course on understanding 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.

The 2012 Seminar will include lectures in direct-digital PM noise measurements, how to specify frequency uncertainty, oscillator needs for new radars and surveillance systems, GPS vs. other global navigation satellite systems, photonic (laser-based) oscillators, chip-scale atomic clocks, femtosecond laser dividers, active PM-noise reduction techniques in oscillators, millimeter-wave applications and noise measurements, and ultra-low noise amplifier design techniques.

This seminar is a must for planners, managers, scientists, engineers, laboratory technicians, and educators involved in the use of time and frequency systems. It presents techniques related to the analysis and evaluation of oscillators and frequency standards. It is particularly appropriate for those who are or might be responsible for certification of oscillator performance at levels where traceability to national standards is a useful part of this certification.
