OVERVIEW
The National Institute of Standards and Technology is offering a
comprehensive 4-day course on understanding the characteristics of clocks and
oscillators, making precise time and frequency measurements, and
synchronizing precision time systems.
The 2009 seminar will include the newly published
"Handbook of Frequency Stability Analysis" by Bill Riley. Also, new lectures will be included
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.
Notable 2009 lecturers include:
John Vig, 2009 IEEE President
David Allan, creator of the famous Allan variance

Other topics will include introductory and advanced frequency synthesis
techniques, uncertainty analysis, applications in wireless cellular phones
and broadband telecommunications, and aspects of legal metrology, traceability,
ISO compliance, and laboratory accreditation.
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.

answered at the seminar, go to our Example Seminar
Questions page.
FREQUENTLY ASKED QUESTIONS
What will I receive at the seminar? You will receive a
concentrated, 4-day course, lecture notes and reprints, a CD and a USB key containing
lecture presentations, lab demonstrations, metrology certificate of completion, the latest
version of STABLE for Windows (software for frequency stability analysis),
tour of NIST’s primary standards and research activities, an evening
reception, continental breakfasts, three lunches, refreshments, and a seminar
gift.
How much experience do I need to benefit from this course? This
seminar begins with the basics and proceeds to advanced topics by the end of
the week. Therefore, attendees of all levels of experience are welcome.
Is this a “hands-on” course? Yes. The seminar includes a full
afternoon of lab demonstrations at NIST. A morning is devoted to analyzing a
wide range of frequency and time stability data using STABLE for Windows,
which is provided for you. Interactive sessions throughout the seminar allow
you to ask questions to our expert lecturers.
