[time-nuts] The Nature of Noise

With my recent Cs problems, I've been wondering about the subject of noise generation and measurement. Specifically, my question is this: Let's say that I have 3 disciplined oscillators: A, B, and C. So, I use the same 5370 to create a 1000 second ADEV and discover that the 1s noise value between A and B is low, while the 1s noise between A and C, as well as B and C is high. Can I then say that both A and B are low noise devices? Or is it possible that even though I'm measuring 1000 points, both A and B are high noise devices, but somehow are noisy in the same exact way, and it's actually C that's the low noise oscillator?
