Mark,

Ditto this. On 6T's and M8T's both.

The 6T's do have an odd issue once in a while, right at the roll over
limit from +10.whatever nS to -10.whatever nS, sometimes the sawtooth
value comes in with the wrong sign.

We were playing with the 6T's in a GPSDO, against a good crystal it
stuck out really well in the graph. A software check in the GPSDO looks
for this and fixes it. Seemed like it happened about once a week to once
a month type timeframe.

Have you noticed this in your hardware?

It looks like you have slipped a decimal point somewhere (also that "ps" label is wrong). I have an M8N running here and the report sawtooth errors are all within a ± 10 ns span. (and LEA-5T is ± 5ns).
