For me it is a rule of principle: If the HP5370 is clocked from the same source I'm measuring, I can have no expectation of a well behaved noise from the triggers. The "noise" you saw is probably exactly that: Overly optimistic results if you clock the counter from one of the DUTs -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
