Today, we have a nice demo of the world's lowest-power atomic clock, the chip-scale atomic clock (CSAC), and we're measuring it using Microchip Technology’s 53100A phase-noise analyzer. As a reference for this measurement, we're using a rubidium oscillator, the miniature atomic clock.
We have a GUI running, called TimeLab, and this is acquiring data in real-time of the frequency drift of the CSAC versus the miniature atomic clock. This is displaying the measurement from the 53100A. Here is phase noise, and you can see it's demonstrating a measurement from 0.1-Hz to 1-MHz frequency offset, and it's simultaneously acquiring phase-difference and frequency-difference measurements.
It also shows the frequency-difference plot and Allan Deviation plot. It has basically anything you would need to quantify an oscillator and has all the stability of metrics being acquired in real-time.
There’s another GUI we call Clockstudio, a free software program developed by Microchip. It’s telling us information about the clock performance on board, like the temperature, voltage, and all sorts of other important information for designing in your atomic clocks.
