Antonio - Folks have short (days) and long (multi-year) plots of the EFC in their Z3801A. The EFC is the correction factor to keep the 10811 inside phase-locked with GPS. At www.realhamradio.com you'll see an index of many many people's EFC plots. My unit shows a fairly steady aging drift with random EFC jumps, typically once or twice a week, but sometimes it goes weeks between jumps. My gut feeling is that the distribution of times between jumps is Poisson, but only because I'm a former nuclear physicist :-).
