The interesting thing about the 10 MHz is that it is “clean enough”. The signal was designed to feed the reference for things like counters and spectrum analyzers. It’s plenty clean enough (spectrum, phase noise, and ADEV) for that use. There are a *lot* of 10 MHz OCXO’s out there with a spectrum that is not as clean of sub-harmonics as that output.
