Subject: RE: Logic Analyser Advice
I have an HP1630 of some flavour and find it very useful. AFAIK it was the
last
series of logic analysers from HP to have proper
service manuals...
The difference between the various models (suffix letters) is which
timing/state input boards are fitted.
For the old computer people here, it's controlled by a 6809 of some
flavour.
There is a 6829 MMU chip in there as well, one of the
few times you will
see
one of those.
You want to download all the manuals from Keysight. There is a lot of
useful
information in them
I grabbed the manuals, thanks! The power switch is a bit sticky, so I need
at least to try to fix that, so the service manual may help.

likely to be
suitable alternatives?
I assume you have the pods themselves -- the little boxes on the ends of input cables.
Yes I do have the actual pods. They look like the picture in this listing
(not the item I bought): http://www.ebay.co.uk/itm/152233591570
So, yes I have the pods, but no connectors
The probes/wires that go into those are totally
passive just bits
of wire with grabber clips on the end. The connector that goes into the
pod is
an HP special housing, but that was just for
convenience.
There are normal pin connectors down the holes, and I suspect the Ebay
listing you have given would fit.
I will buy a set and see how it goes. I also believe there are some probes
that are designed to clip over a whole IC, any recommendations for those? I
did try using one once but it was designed to be used in conjunction with
grabber clips and it was so fiddly that I gave up, so I am wondering if
there is something better.
Thanks
Rob
Be very careful if you take a pod apart, there is a delicate ceramic
hybrid
circuit inside.
