Hi Graham, the TSC5125A has auto-scaled the plot to 2E-04Hz fractional frequency from 10MHz, or in other words one vertical division is 2E-011 at 10MHz, or 20 parts per trillion, or 0.0002Hz error. I also don't like the way the TSC shows the frequency, and the fact that you can only capture about 9 minutes of information for some reason. Why not show 24 hours or 48 hours of data here? With this in mind, the FE5680A wanders around about +/-6E-011 max in this plot. Hope that helps, Said In a message dated 1/4/2012 13:41:07 Pacific Standard Time, time...@austin.rr.com writes:

Performance has improved significantly, ADEV is now in the xE-012's. Phase noise and spurs are worse than originally reported, they kind of suck. Frequency over time looks quite nice though, definitely quite useful as a frequency reference. bye, Said Said: Your vertical units per division for the frequency plot don't make sense. Please re-check and let us know.
