I really cannot see why everybody is on bd's back, OK, it's a Tek, etc, but as he has already stated he does have a reason for his actions and also the TDS210 is perfectly adequate for his stated purpose, audio work, even with its crappy digital display and lack of memory depth. Yes, we all know that analogue scopes have a far better display, I have both a Fluke PM3390B 200MHz combiscope and a Tek TDS210, but the TDS210 gets used most because it is quick to switch on, actually sits on my bench so is right in front of me and takes a very small footprint.
If I had bench space like a lot of you have, then I'd probably use the combiscope more, but space prevents it from being the main go to scope. Yes I'd like a colour display etc. but really cannot justify the cost, so the TDS210 suits me just fine, and I daresay bd can identify with a lot of that as well.
All this hating on Tek TDS210s just makes me want one more.
Compared to the old Hameg 20MHz analog scopes I used at college and work, it's pretty fancy, as is my TDS420.
A real problem with the 2.5k points is that it can't emulate the traditional dual-timebase technique to zoom in. I know there are sort-of-workarounds, but it took me a long while to realise the TDS340 was unpleasantly deficient in that regard.
To be fair to the TDS-210, they're cheap, they're fairly rugged, and they're compact and they do get the basic job done so they do have their uses. I'd toss mine in a bag with some adapters and cables, and a power cord and take it on the road along with a small HP function generator whenever I was going to buy test equipment or if I was going to be doing test or service work. I've gotten more than the $60 CDN of use out of mine for that purpose and if anything bad happens to it, it's not the end of the world since I don't have much money in it. It's only recently that I picked up an inexpensive Agilent u1602b handheld scope that's replaced it for that purpose.
On that note, does anybody have any recommendations for a battery powered portable, ideally similarly ruggedized, function generator to add to the road kit?
