--- 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.

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. Frank |
