I've spent a good deal of time this weekend working with the 5061B I recently acquired. The unit appears to be making stable 10 MHz. I've compared it the the Rubidium source I have and the two compare as expected. There are two problems: 1) Beam current is low - even after going carefully through the alignment procedure outline in the service manual, the best I can get (Loop Open, Mod Off) is a bit over 10 nA. 2) The "Continuous Operation" LED will not come on after pressing Logic Reset. I used the trouble shooting guide to diagnose the LED and it's pointing to the circuit on the A14 board. This is as far as I have gotten so far. Note that the trouble shooting guide is suggesting that it might not be a problem with beam current, but an electronics problem (the LED driver). Anyone have any insight? Thanks for reading. Jeff
