Proven on Deep space applications
AccuBeat’s USO is a high-stability quartz crystal oscillator utilizing a high Q crystal resonator and high temperature stability in the range of 100µ kelvin. The USO designed by AccuBeat, has an Allan Deviation substantially better than the required spec of 5E-13 at integration constants of 1 to 1000 seconds, making it the most stable oscillator of its type designed for deep space exploration as can be seen in the following graph. (Note that the glitch at the beginning is due to the inaccuracy of the Hydrogen MASER reference at 1 second). AccuBeat’s USO has been designed to meet this specification while subjected to demanding EMC effects and the harsh environment around Jupiter with radiation levels reaching as high as 100kRad on some internal components.
