It's an interesting historical confluence: 8.5's are the clippers of DVMs. 8.5 only makes sense two places: fundamental/high-end metrology and basic research. Everybody else are totally fine with 7.5 and very few actually need more than 6.5 (specifying the temperature of your aligator-clips gets old really fast.) The 3458A made it possible to validate the josephson junction as SI voltage reference -- which ironically made the 3458A surplus to metrology requirements: Now you can generate any voltage you want on demand. That leaves a theoretical market in basic research, but that's a very small market which will happily pay a phd-theses for a prototype, but unless its on CERN scale, production runs are never an option. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ volt-nuts mailing list -- volt-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
