Same here with the memory upgrade on an early 34465A. Very pleasant surprise this morning!

--- Quote from: Dr. Frank on March 07, 2016, 09:15:43 am ---For the 3458A, you see a typical, quite narrow Gaussian distribution for the 10V measurement.
At 10x magnification, an irregular binning appears, with 7 different values per 0.01ppm, which gives about 17.5nV median resolution, or 0.00175 ppm, nearly 9 digits.

Was this measure at NPLC=100? Did you use auto zero?
Have you calculated the minimum standard deviation(or allan deviation) for a consecutive 100 readings?

Yes, it's the same measurement as in the Allan Deviation diagram, i.e. 35h vs. 5442A, NPLC100, AZ ON.
You may take the SD from that diagram, at about tau = 500sec.
Otherwise, I may look for the original xls sheet, so that you can analyse data on your own.
