||Ultra low-noise system for measurement of short-term frequency and phase stability
Ludvík Šojdr, Ph.D.
The project goal is to establish a metrological center for ultra
low-noise measurement of short-term frequency and phase stability. The
measurement system will serve for investigation and calibration of ultra
low-noise frequency sources, frequency conversion systems, precision
signal transfer systems, distribution amplifiers etc. The measurement of
frequency stability in the time domain will be based on the Dual Mixer
Time Difference (DMTD) method that will be elaborated within the
project. The measurement of phase stability (phase noise) in the
frequency domain will be based on the existing industrial equipment
provided by Femtosecond Systems (FS) which will be appropriately
implemented. It is expected that other European time and frequency
laboratories will employ the center within the related EUROMET (European
collaboration in measurement standards) Project #651.
