This seminar provides an overview and and details of time and frequency metrology. It focuses on fundamental concepts, measurement techniques, metrological traceability, and data and measurement uncertainty analysis.
Lecture topics covered will include:
- Fundamentals of Time and Frequency and basic terminology
- Quartz Oscillators
- Atomic Oscillators (rubidium, cesium, and hydrogen maser)
- Laboratory Instrumentation
- Measuring Frequency Accuracy in the Time Domain
- Estimating Stability with the Allan deviation and related statistics
- Stopwatch and TimerCalibration
- Traceability
- Uncertainty Analysis for time and frequency calibrations
- GPS/GNSSand GNSS-Disciplined Clocks and Oscillators
- The Network Time Protocol (NTP)
- Applications of Time and Frequency Measurements (telecommunications, electric power, stock market trading)
