I got some updates: The RMS jitter goes down to 25 - 30ps if I don't use "Preset" but rather very carefully adjust the trigger level settings. There is one position on the trigger pot that is extremely tight (maybe 1/5 of a mm turn adjust on the pot!) where I get readings down to <30ps. With that, I can actually use the instrument in 1K average mode on TI and get readings that are meaningfull in the 10's of ps. Great! A lot better than my 53132A. Seems I really do need to cal the unit carefully but I don't have the calibrator needed. I remember someone mentioning a gentlemen somewhere that specializes in calibrating this unit, does anyone here have his info? Does Agilent still cal the units? Thanks, bye, Said ************************************** See what's free at http://www.aol.com. _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
