Abstract :
We report the results obtained with a frequency instability measurement system based upon the dual-mixer time-difference scheme working at 10 MHz with a 1 Hz beat note. It shows a two samples (Allan deviation) measurement floor of 5.6.10/sup -14///spl tau/ and a temperature sensitivity of some picoseconds per Celsius.
