Overall, I agree that a voltmeter such as the 3458A may not be cost effective any more to redesign all functions from the ground up. Consider that Fluke has re-released the Datron 1281 as its 8508 voltmeter. A quick view of the specs shows that Fluke has made marginal improvements to the DC volt side, good improvements to the DC current and Resistance side, but largely left the AC volt and AC current performance alone. Never mind the 8508A 20A current range, which seems to me like a bolted on afterthought. Fluke has added functionality for PRT measurements, and replaced the vacuum display with an LCD. Does anyone want to check if Fluke kept the 68000 processor and its architecture ? regards, ben -------- Original Message -------- > From: "Poul-Henning Kamp" <phk@phk.freebsd.dk> > Sent: Wednesday, May 13, 2015 4:55 PM > To: "Discussion of precise voltage measurement" <volt-nuts@febo.com>, "John Phillips" <john.phillips0@gmail.com> > Subject: Re: [volt-nuts] "*WAY* too expensive for even Keysight to redesign" > > -------- > In message <CANEyv6aTuFHYa17nkx3F7zTWqerTiC1o=D=fCz8SXar3zGpEcQ@mail.gmail.com> > , John Phillips writes: > > >I would think that a lot of the patents would be running out soon as if > >that would make any difference. > > I wrote "copyright", not "patent". > > Thanks to Disney copyright never runs out as long as a lawyer cares. > > -- > Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 > phk@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.
