Some time ago I asked about connectors for the pods on a HP 1630G Logic 
Analyzer. The reply above mentioned molex connectors as an alternative. I have 
been having a bit of a look around but I don't seem to be able to find anything 
suitable. Does anyone know what might be suitable?

I reckon I did enough of the right thing ensuring it had pods, thankfully
the connection to the actual probes looks simpler and I am hoping the item I
ordered a couple of days ago will work, we will know in a day or so.

I finally managed to pick up a logic analyser for a price I could justify.
It is a HP1630G and it comes with a number of pods. However the pods do 
not

seem to have the actual wires/probes. Is there a separate part number for
these that I should look for. There seem to be quite a few items like 
this:

http://www.ebay.co.uk/itm/291753390848, are these likely to be suitable
alternatives?

The key for me was to find the original Tek part number for the pods and
probes, and then search for that. The same might work for this HP thingy.



I have tried that, not found much so far (one item on the wrong side of the 
pond), but I will keep looking.

I have a bunch of what you're looking 
for my 1630G pods, but in looking at 
them, I'm not seeing any part #'s of any 
kind stamped directly on them... which 
is likely going to make them a bit 
harder to find.

3M / A P Products have a couple of versions of DIP test clips - the
headless version and the nailhead version.

For logic analyzer use you generally would want to use the headless
version. The logic analyzer flying lead ends should slip directly on
top of the DIP test clip pins.

The nailhead version as the name implies look somewhat like the head
of a nail on top of the DIP test clip pins. That is to stop a clip
from slipping off the top of the pins, but it is a real pain to have
to try to fit clips on all of the pins in the space available and make
sure none of them pop off.

DIP clips?  They can be found, but since DIPs are mostly considered
obsolete they are pretty pricey these days.  Watch on ePay - I picked up a
raft of them from some company closing its service department (cheaper just
to throw things away).  The grey plugs that fit into the end of the pods
have a connector  that fits over an individual pin - they work great on
wire-wrap pins! - and those can be attached to the DIP clip before you
clamp the clip on the IC.  There have been a couple of times I've had every
single pod in play, each connected to one or even two DIP clips.  -- Ian

Quite a beast, with 288 channels at 10 ns.  They have 
transmission line cables to the pods, but the pods are 
passive, I think a parallel 82K resistor and a 1000 pF cap 
or something.  I made a VME analyzer card that has about 80 
channels wired up with those parts so the TLCs just plug 
into the card.


We have a DAS 520 at work, which is basically a 9200.  The 
9200/TLA500-700 series are not stand-alone analyzers like 
the old HP and Tek 1240 series.  You can use an X-windows 
terminal, or connect to it with any Xserver.  You do have to 
download fonts and make some adjustments to the setup file 
in the analyzer to make this work, however.  The analyzer 
mainframe runs a version of Unix.

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.

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

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.

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 assume you have the pods themselves -- the little boxes on the ends of
the input cables. 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.

Be very careful if you take a pod apart, there is a delicate ceramic hybrid
circuit inside.

Not necessarily. I bought a couple of Tek 1240's, without pods or probes, but
managed to locate a goodly supply of each on eBait.

The key for me was to find the original Tek part number for the pods and
probes, and then search for that. The same might work for this HP thingy.

Re: Logic Analyser Advice

On the 1630 series, the active logic is all in the pods.  The connectors on the 
flywires are proprietary HP parts with a mechanical latch to lock them into the 
pods. but I've seen multiple mentions in discussion groups of folks using stock 
Molex connectors to connect to the pods.

Do you have the grey rectangular bits that plug into the pods?  If not,
you're pretty much screwed - they are (were) a proprietary part.

I have a 1630G and I really like it, but I held out until I could find one
with the bits that plug into the pods, since they are unobtainium.
