Plz elucidate Jon. Something has got to be better than this. See the pix I posted with the last reply to Peter & the list. The top, white trace in the halscope screen is the quadrature noise, easily 10x the timing wibbles I see on the hitachi's screen. > ---------------------------------------------------------------------- >-------- Developer Access Program for Intel Xeon Phi Processors > Access to Intel Xeon Phi processor-based developer platforms. > With one year of Intel Parallel Studio XE. > Training and support from Colfax. > Order your platform today. http://sdm.link/xeonphi > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
