Skip, There is a great deal of expertise as you know here. So several comments to get the ball rolling. The zeeman frequency allows you to establish the optimal beam current main peak by changing the magnetic field. What this is really doing is optimizing the state of the cesium atoms. Its physica

Hello Time-Nuts, I have an HP 5061A (relatively new chassis) with a very old Cs tube installed (working) and I’m trying to wrap my head around the set up and calibration of this unit, and just hoping for some help. As a little background, HP changed the Zeeman modulation frequency, C-field in
