Hi all, Has anyone here who is familiar with hydrogen masers ever experienced a sudden jump in phase of the 5MHz output?
We have found they occur semi-regularly (few times a week) and are trying to find a culprit. The weird thing is that the jump is ~0.7ns and that 1/0.7E-9 is close-ish to 1420.4MHz which is the hydrogen line. Too much of a coincidence for me. These seem to be appearing at three different locations with the same model of maser at each location. I won't mention the model publicly. We're still investigating various potential causes (e.g. power spikes, cables being moved), but this 0.7ns figure is niggling me. Has anyone here ever seen such a thing before?
