Just saw this topic. My go-to for precise time/period measurement has been the venerable 5370A. Aside from the obvious improvements such as a graphical display, history, etc., from a pure accuracy/resolution perspective, which would you pick for precision measurement? I suppose this isn't a particularly fair question, given all the additional features of the 53310A, but my typical use has been measuring such things as phase diff over time between various high-precision oscillators (example, my cesium-beam osc and a GPS-disciplined osc). I have an opportunity to pick up a 53310A, wondering if I should.
