HI Bob, 10 nanoseconds at the bottom, up to 10 microseconds at the top, in three logarithmic sections.
Donal: Is the time-constant at its default of 100 seconds, and was the above plot taken shortly after turning it on? There has been lots of talk on here about tweaking the performance. Increasing the time-constant to between 500 and 1000 seconds should help, as will stabilising the environmental temperature. Let it run for a few weeks, and the oscillator will settle down, and you should get some better results.
