I can't vouchesafe John's decision to give up his treasured gear,
but I can say John's loss is my gain. John's 8566B is a beautiful
machine and several of us are having lots of fun with it. My tech
is making a new rack for it (and several other machines, together
far too big to fit on a bench), then I'll add an ethernet-to-GPIB
network connection, software, and it'll be ready for prime time.

Glad to hear it's working well. Agreed, its size and weight is a real
problem, and not just for shipping. I'll definitely own another of
those beasts at some point, when I have more room than I do now. The
important thing is that it's in appreciative hands. :-)

If you plan to use my GPIB software with it, be sure to download a
recent copy. I hosed the phase-noise app pretty badly in my last
"slipstream" update a few weeks ago, and only heard about it last week.
The version that's up there now is fine.

Would you be so kind as to post the url for your website? I would like to
get a copy of your software.

Thanks, K

http://www.qsl.net/ke5fx/ Thanks for the heads-up. That's v1.05,
the Jan 14, 2006 edition? Which program was updated to fix the
phase-noise problem? The pn program's source code says 13-Jul-05,
although the pn.cpp file date is 12-Feb-06.

I like the part where you get the "number of 1000-ns intervals
since 1-Jan-1601 UTC" :-)

The broken version was 1.05, but I "slipstreamed" the fix into the same
release without updating the version stamp.

I really should've bumped the version number when I posted the fix, but
it'll be pretty obvious if your copy has the bug. It will appear to
work, but it will always start the PN sweep at 0 Hz rather than the
minimum offset you specify. That makes the sweep take much longer than
necessary, and the trace information at offsets below 10x the
analyzer's minimum RBW is meaningless.

Basically, if you downloaded it around the time I posted all those
auctions, you probably got the bad version.

Heh... I've wondered where Microsoft came up with that; it might have
come from the Unix world. There's a lot of weirdness in the calendar
business, and it's usually less arbitrary, but more obscure, than it
seems at first.

Do you take into account the days lost in the change from the Julian
to the Gregorian calendars?
