Very nice, I think. Although I suppose I still have the problem of not
knowing exactly the frequency of the OCXO is, after all there are
coarse and fine adjustments on the can...


Well, there is WWV :-)


Eh, still, I'm pretty happy with the cheap stuff you can get with a
bit of patience.
I think that I will build a 10V "standard" from my AD588s, in a nice
box.

So, what kind of connectivity do you guys have in yuor lab? Is
everything GPIB, USB, or some mix?


A mix, and that's unavoidable. Older gear that is irreplaceable
(because they simply don't make some of the good stuff anymore)
inevitably comes with those dreaded HPIB garden hose connections. The
logic analyzer and some other gear I rarely use is from the RS232
era. Modern gear like the DSO is USB. And I will absolutely not have
HPIB garden hoses here anymore.

So, there is a Prologix HPIB/USB adaptor, an RS232/USB adaptor plus
the traditional USB spreader octopus. I raised the equipment rack by
1-1/2" to make all that fit underneath, plus scope probes, chargers,
international outlets, a flat vise and whatever else is needed during
lab work. Nice thing is, a laptop can now talk to all the important
boxes.


I'm so used to GPIB that I'm probably not a good example. It's a
great deal nicer than RS232, and given that it's been around so long,
I don't have to worry much about OSes not supporting it in
detail--unlike USB.


GPIB is terrible. The topper happened a long time ago, after I had just
laid new carpet. Connector slipped off, the garden hose cable
ricocheted, hit my coffee mug which was half full ... *THWACK* .... flew
off and crashed onto new carpet. That was the end of GPIB for me. There
sure are better busses out there. I used to prefer RS232 but now
everything is USB.


A nice Prologix GPIB-Ethernet is next on my list.


If you have to use equipment at clients a lot and its legacy HP stuff
the USB version is very practical. Plug it in, hit print on the
analyzer, done. But Abdul (the Prologix designer) and I had to iron out
a bias problem before it liked HP legacy gear.


Spilling coffee is a criticism of a bus? GPIB can do about 1 MB/s when
externally clocked, which is better than good enough for most things I
need to do in the lab, and if I tighten the screws I can even keep my
coffee and my carpet. ;)

Joerg is accident prone... always *PHUT*ing ;-)


He always has one *PHUT* in the grave...

Very good!

We need to have an SED get-together. If I hosted it, say in April,
when AZ is absolutely delightful weather-wise, who would come?

I'd have to think about it. It's quite a trip to roast weenies.

Only "weenies" I'd roast would be liberals ;-)

We might possibly have "Brats"... more likely ribs and steaks.

And kegs... for the youngsters, vino de casa for the adults ;-)

And the path would take me past Eschbach's (a first class German
butcher shop, compleat with smokehouse).
