Hi,
I rescued a TDS749D and am looking for suggestions for a "cheap" set of probes. I don't use/need a 'scope often (I tend to use a logic analyzer for troubleshooting) so not keen on putting much into this "freebie".
Thx,

gack! s.b. TDS754D a "cheap" set of probes. I don't use/need a 'scope
Well they go at about $20 on 'hebay
Thanks, I may try that! On a hunch, I called back my supplier to see if, perhaps, the probes for the 'scope may have become separated from it (in a bag or box, someplace). This appears to have been a good idea! :> A pair of 6139A's, two 6339A's and two 6249's!!! Can't see using anything day-to-day beyond the
6139A's -- and, may prefer to set them aside as well and spend a couple of dollars (your eBay suggestion) on some cheap ~200MHz probes!
Feel like parting with the 6249s?

Sorry, Phil... they're small enough to squirrel away in a desk drawer until I need them (if ever!). Had they been something larger and more tedious to store, it would be a different story! (I'm on a downsizing kick)
No worries. I have a couple of them already, but one looks like it has a blown cap in its bias loop or something--it oscillates at 2 MHz. Not your usual scope probe, in so many ways. ;)
I usually pay about $200-$250 for them on eBay.

Doubt I would ever *buy* one! OTOH, knowing that they're squirreled away in a drawer ("Hmmm... now WHICH drawer was that?") makes it far more likely that I'd use one when the need arose (instead of thinking up a way NOT to need one!)
[Buying online is delightful -- except for the fact that you never end up "coming home" with what you wanted, *now*!]
I got a dead one for $30, which I'm going to take apart, so that I can copy the layout of the scope end, which has all the pogo pins. Then I'll build a little breakout board so I can use my fave pHEMT/SiGe cascode to make higher impedance ones. Beautiful Layout Hunchback will be underemployed for a couple of weeks, once she and Dashing Firmware Hunchback get the last touches done on the current board. (Their actual job titles are Head Designer and Chief Scientist.) ;)
The five of us are off this evening to visit the World War 1 Western Front battlefields for a week. Should be a great trip--my two younger children have never been there.

(sigh) I don't envy you! If I'm lucky, I'll make it through the remainder of my life without having to set foot on a plane again! Especially commercial aircraft. :-/
(And, the idea of a boat trip that long "in transit" is one that I can't even begin to fathom :< )
We had some tthat had some terrible ringing on a 1 mHz square wave. I mean really bad. And the generator and display were confirmed to be good. Cheap ass fifteen buck probes, that's what it was.
TJurb The Clown :
By judging your other posts it is safe to assume you do not know about that adjustment screw. :-) Fuck 1 milli Hertz, and that babbels about old threats. Can you even calculate how long you have to wait for the next ringing?
Maybe he's more concerned about the screws in his head?
