Hi Said, > I sent spectrum plots of the 10MHz 5370B output to this list earlier, the > output is very sad. It's extremely dirty and jittery (well, compared to the > 4ps noise you got, and compared to what the 10811 can deliver). OK. So you have seen it too. I will ponder a little about if there is a cure for it. Fortunatly the Frequency Buffer Board is fairly easy to get to. I'll think I'll handgranade a hole on the lab-bench and pop the lid there. > After calibration to 4ps, what does your 5370B unit read for it's internal > RMS noise now? Still annoyingly high. Don't remember the actual number. It was jumping around like hell. I was not doing it properly thought, so I will redo it later tonight. I'll also see what kid of numbers I can get from "good" sources. There is plenty to pick from here at home.
