TDS-1002b Any good? Comments?

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 !

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

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

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. ;-)

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.

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 ;-)

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.
