TDS-1002b Any good? Comments?

[Eeyore]

I meant "cannot shield". The old stuff is generally quiet. I prefer
older equipment because it won't have switchers and the like. In my lab
here about the only thing that is noisy is the computer so it needs to
be off at times. Well, and our Rottie who sometimes comes in for a while
because he snores.

LOL !

I do recall having to switch off monochrome or EGA monitors when performing
audio tests too back 'in the days'.

This one's scanning at ~ 90 kHz so no trouble there !

You're not an analogue man at heart are you ?

I'm electronically promiscuous. I'll design anything.

HP have indeed done good stuff but not IMHO as good as Tek's until I came across *THE
TDS SERIES* !!!!

AAARRGGGHHHHHHH ! KILL KILL KILL !

You know what I'd like to do ?

I'd like to get a really nice AXE. Also a decent 'stone' on which to polish its'
edge.

I would spend some time putting a very fine edge on the AXE until it could cut my own
flesh and draw blood with a mere graze.

I would them place the TDS on a solid oak bench and chop the living daylights out of
it with a thousand cuts !

That would not satisfy me however.

I would make sure I had a decent pair of Doc Marten's boots with steel toe-caps and
additional hobnails.

The chopped-up remains of the TDS I would sweep onto the floor and then stamp on up
and down for at least 5 minutes !

I would then collect the remains and transfer them to a quartz vessel where I would
mix them with aqua regia.

Once so dissolved I'd neutralise the mix and incrporate it into a load of cement. The
cement I would cast into a block and then when solid would knock to pieces with a
ball on a chain.

The pieces I would collect and feed into a rock crusher.

I would finally drop the crushed rock from a helicopter into an active volcano.

And I'd still be cross !

Or you could simply sell it on eBay and buy a lot of beer or
something :->

It sure does. The 2465 is what I usually recommend to clients. Then they
get them on EBay or through other places. Best scopes Tek ever made
IMHO. With those new little bread-box thingies I have the impression
they are just some kind of outsourced design. Like what HP used to do
with Yokogawa designs, except that the results, well, ...

The only downside with the 2465 series is that they are only available
used. And since they are some of the best scopes since sliced bread that
means used a lot. So all the encoder shafts are usually sloshing around
or like what happened to us you pull into delayed-trigger and hear
plastic pieces rain down behind the front panel, meaning it won't switch
back to non-delayed. Anyhow, it's best to budget in some serious
mechanical fixing. The knobs, shafts and so on are IMHO a bit on the
flimsy side.

The 2465 is quite a nice scope for some analog work. Mine gets used on
occasion. They are useless for digital work and I sometimes forget that
when I am at the wrong bench with the digital stuff. Low duty cycle is
a killer. The tds3000 are really nice and make it harder to go back and
use the 2465 even with its nicer user interface. No storage for
averaging or looking at noise either, just you and the phosphor.

You also mentioned the 7000 series scopes. Here you cannot give them
away. We set an entire truckload to the landfill because of that.
The only I have left has a tdr in it.

We have the same problem with Tek 2465's, we have them stacked up in
storage to the ceiling, nobody will touch them with a ten foot pole,
one guy uses one to prop his monitor up higher in his lab, that is
about the only use they get.

I really like my eight or ten various TDS scopes. I rarely use my
analog scopes any more, even though I have maybe 40 of them.

The 7000s weren't super reliable, and those tiny buttons were a pain.
And the TDR was fairly primitive, tunnel diode pulsers and all that.
You can get an 11801/SD24 rig on ebay for a few kilobucks, seriously
good, quantitative TDR.

Something like a 545 or a 547 is collectable art; no 7000 series scope
is.

I'll gladly pay shipping costs for a good one.

We had really good luck with a pile of 7904s. We had very few 7704s.
I only remember the DPO (a 7704 with a digitizer in the middle). The
7S11/7S12 wasn't at all bad for the early '70s.

There are *lots* of 7000 series scopes floating around. 1970 pennies
aren't worth much either.

I liked the 465 and it's siblings.

I've got a real horror story about one company that decided they can do
it on their own but I can't tell it in public. Suffice it to say that
there came a loud kablouie, after which their stock price plummeted to
less than 0.1% within a few weeks. Actually, I also got a 2nd horror
story but now I am getting carried away into OT.

I'll see your shipping costs and raise you a bottle of scotch. ;-)

I can see the ad now: "Do you have unwanted analog oscilloscopes?
Don't put them down! Put them up for adoption in loving homes where
they'll get the care and attention they deserve."

Exactly, my motivations are purely altruistic. ;-)

 

[John Larkin]

Interesting. It just came to me: All of the potential clients that have
decided to use my services and thus became clients are under the CEO
leadership of an engineer, a scientist or at least a technical-minded
person. And for some reason they regularly blow the competition out of
the water.

Sure. If you care about the technology, the money just happens. If you
care about the money, the technology may well not happen.

Depends on who is in the lab. When I had the Viewsonic terminals our
younger dog would get up and leave after turning it on. I guess the
flyback transformer whine bothered her. She gave me "the looks" before
leaving.

2465s are fetching decent money on ebay.co.uk.

I'll help you get rid of one for sure !

Maybe offer them through your web site or EBay? Some of my clients would
probably bite. Although the recent one only needs one more 2465 and they
have some bids out. But one never knows, on EBay the common strategy
seems to put in your final bit a few milliseconds after time is up. Kind
of like the opposite from what we do to get SWA boarding passes ;-)

 

[Joerg]

Same here. Not that I need one right now but it would get a loving home.

Yes!

I'm sure that business school 101 includes a heavy dose about how you, too,
can run a multi-national Fortune 500 technology company just fine, even if you
never understood any of that math and science stuff they tried to teach you
back in high school.

I'm a collector! I never sell!

I don't have many portable scopes, maybe a Kikusui or two. Mostly big
old mainframes... 535's, 545's, 547's, 7000's, a few HP180's, a few
exotics; a zillion plugins, many sampling. I do have an HP185 4 GHz
sampling scope ca 1961, with plugins and manuals; *that* is a chunk of
history, if an ugly one.
