Hello all. I looking around for a Logic Analyzer for doing (mostly) DEC QBus/UniBus
stuff. Being the way I am I want something with enough lines to handle the most of the
signals so I'm guessing something with roughly 80-ish channels. I think that lets out
all/most of the USB based LA. I've looked around and it seems the the HP/Agilent
16700 series (16700B/16702B) are probably what I want. I've also seen the 1670G which
also seems quite doable. I've seen a lot of posts at the EEVblog and it seems I
missed possibly the golden age of 16700 LA by a few years price-wise.
What I'm wondering is if there is something specific I should be looking for, or
opinions on which LA is more suitable. Or even if there is a different make of LA to look
for.
Thanks in advance for your help

Where are you located? That can have a large impact on the cost of
acquiring a large 16700-series logic analyzer. For example, I have more of
those than I need in the Seattle area. A local deal might work out well,
but if shipping is involved that can quickly get too expensive.
If bench space is limited, a 1670G takes up a lot less, and is completely
self contained and easier to move around and set up. On the other hand, a
16700-series is more flexible, and if you have space to set up an external
monitor you can see a lot more data on the screen at the same time without
scrolling around.

Hi Glenn,
Thanks for chiming in. I've seen you post often on the EEVblog about various LA.
I knew I forgot something. I'm in the Fort Worth, Texas area. So middle of the
country length-wise but down South. I've seen shipping on Ebay range from
"included" (which is kind of scary) to $350 and "freight".
My bench space right now is kind of limited but I'm hoping in a few years (retirement)
I'll have a bigger space to poke around in. The 1670G is interesting in that way.
There seems to be a pretty complete one (Options 002 and 003 - OSC and memory) on Ebay but
that's the place that's charging $350 for shipping.

Another option is the Tek 9200-series. I have a 9200 at
home and a TLA720 at work, both with 92A96 cards. You get
fairly deep memory and 96 channels, with very sophisticated
trigger state machine logic, and up to 10 ns/sample rate.
If you go this route, make sure you get the probe cables and
pods with it, they have essentially attenuator probes in them.

There have been a few threads very recently in
https://groups.io/g/HP-Agilent-Keysight-equipment which you would probably
find interesting.
There is a lot of enthusiasm over the 1670 and 16700 machines - I wouldn't
say you've missed the sweet spot since these are now often much cheaper
than the later 168x and 169x machines but still very well liked : not least
because the 167x are based on HPUX rather than Windows.

I'm in Portland OR I have one 16702B and one 16700B for sale. As Glen
says, an external monitor is really nice. There are a few modern LCDs that
can make use of opt B if your unit has it.
I think I have a pattern gen card and one low end acquisition card. Else
the chassis are empty.
The difficulty with the 1670x is the cards (acquisition and scope, not
pattern). They form corrosion under the runners. I had 10 or so cards go
bad over a 5 year period. All now have visible corrosion. I'm slowly
working my way through removing the runners, fixing the corrosion and
repairing damaged traces. There are no schematics but there is a very
helpful active repair thread on eevblog.
In my personal machine my second scope card passes diagnostics but totally
fails calibration. Otherwise the diagnostics are pretty good but they
don't run at boot up so most sellers have no clue how to run them.
Try setting up a distance based search on eBay. I suspect something will
show up given a few months patience but if it includes cards there is a
very good chance they are bad. Don't ever buy a card on eBay "for parts
or repair" unless it's dirt cheap.
Good luck

The built-in LCD on the 16702A / 16702B is 800x600. Without the extra
memory of Opt 003 installed, the maximum supported resolution on an
external monitor is 1280x1024. With Opt 003 installed, the maximum
supported resolution on an external monitor is 1600x1200, but at 75Hz,
which isn't supported by all monitors.
With a 1600x1200 or 1920x1200 monitor which supports 60Hz but not
75Hz, it is possible to use a video scaler to convert between the
16700-series 1600x1200 at 75Hz output to 1600x1200 or 1920x1200 at
60Hz. I tried this today with an Extron DVS 304 DVI video scaler and
got decent results with 16700-series 1600x1200 output on a 1920x1200
at 60Hz monitor. I've had mixed results between different Extron video
scalers. I couldn't figure out how to configure an Extron DVS 510 to
give the same results in this scenario as the DVS 304 DVI.

I just did some research on what LCDs could handle 75hz at 1600*1200 and
bought one (HP) used off eBay. Easy. Problem solved.

The guidance about the 16XX series being bench space friendly is
appropriate, as I went from a 1650 to a 16702A frame and had to devote
much more to the unit, but I am still partial to my 02A frame, now
filled with 333MHz LA cards, function generator, and o-scope cards.
As for HPUX, Using the unit via VNC or X on my main PC just makes life
so much easier and more interesting.
I might be an outlier, as I specifically wanted an 02A, not 02B, because
I wanted the on frame keyboard. Others might prefer the larger screen
of the B.
I most love the option to mix and match cards in these units. I built
mine by grabbing it and a 16500 that has some cards I wanted, swapping
and keeping the best, selling the rest.

In any case, when it comes to eBay sellers of logic analyzers, be very
careful.
I remember asking a seller about a particular HP LA where the claim was
made as "working". But oddly, no test pods were pictured. I asked the
seller about that and the reply was "We don't have pods, but when we
powered it on, we got a display.,.."
Something akin to selling a used car as "working" because the engine runs.

If it's hooked up right, a logic analyzer can also be a powerful software debugging

(Anton Chernoff, I think) who had one hooked up to a PDP-11's console buses. It was
amazing to see execution captured in real time, giving much more power than ODT ever had.
Meanwhile, on logic analyzers: I have a Fluke (Philips) PM3585 analyzer at home,
unfortunately short on pods so I can use only about 32 of the 96 channels. It's
pretty flexible, has lots of channels, and (in state-only mode at least) a decent amount
of memory. No plugins, just a single box. It's not as well known so the price may be
lower, I haven't checked.

I have both, and I end up using the 1670G most of the time because it is so much more
convenient. The acquisition cards on the 16xxx keep failing too.

This was the kit that matched the article in April 1970 Issue of Popular

Yes I can build one from modern parts but I used one of these in 1972
and I would love to get my hands on one, at a reasonable price.
Here is a link to the article:

You could try an AMD (ex Xilinx) logic analyser ...
Basically, use the logic analysis capabilities provided (free) by FPGA OEMs to construct a
DIY LA. In brief, the LA is in the FPGA libraries / GUI, you do of course have to wire
them up both inside (Vivado) and outside (level shifters and copper wire) the FPGA.
Boards which are not too expensive, and have 0.1" (ish) LVTTL interfacing are:
- https://digilent.com/shop/arty-z7-zynq-7000-soc-development-board/ which should yield
~79 digital IOs
- https://digilent.com/shop/cora-z7-zynq-7000-single-core-for-arm-fpga-soc-de…
again ~79
- https://digilent.com/shop/cmod-a7-35t-breadboardable-artix-7-fpga-module/ 52 digital IO

Also unsure what you mean by this. I wouldn't pay more than $150 for an
empty 16700B, $250 for an empty 16702B and if you have patience I suspect
you could get a 16702B with multiple cards for $350 (sometimes with some
really nice cards). Now whether the cards work is another question.
Pricing is all over the place but prices have definitely falling over time.

Hi Tony!
I got the impression that people were finding them for around $100 - $300 back then. The
prices I see on Ebay currently are all much higher. Certainly lower then when they were
new though.
Perhaps it's because I have only been looking about a month and my primary source is
Ebay. Currently on Ebay, that I can see, the cheapest I see is a 16702B with a couple of
16712A cards and no pods/probes for $300 plus $120 shipping and tax. The 16712A are the
absolute minimum I think that would be useful at 100Mhx and 8K/16K memory. I'd still
have to find at least 2 sets of pods and probes.

The next cheapest is a 16700B for $430. It has 4 interface cards but the listing
doesn't say what they are. But it's local pickup only
https://www.ebay.com/itm/314745893438
Then there is a 16702B for $449.99 which looks like and has a 16715A card and pods. But
the detail listing says "failed self test for: VRAM Serial Access Memory Inputs Test,
VRAM Serial Port Cell Test, and System Clocks (Master/Slave/Psync) Test." Not sure if
that's bad but is sounds like it.

And so on. Am I looking in the wrong spot?
Thanks,
John H. Reinhardt

No but you need to look longer and as I said prices are all over the
place. I see resellers asking for $1500-2000. Do a sold items search
and track the results over a few months.
Good luck
