Bruce, Can you clarify about the jitter, though. The TIC jitter that was quoted (500 ps) is the single-shot resolution for the 53131A. The "2 ns" M12+ jitter is an rms value, no? The short-term or "single-shot" M12+ jitter, if you could call it that, is more like +/- 20 ns. Averaging it, over many minutes, gets you below 10 ns. Also the sawtooth correction helps even further but that isn't being done with Shera's board. Maybe we're all agreeing even if with different words. /tvb _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
