Very different ballgames. SMPS mostly needs a good analog scope, uC needs digital storage.


Any suggests of what to look for?

I've been browsing Ebay.
I've been looking at Tek scopes from the 90's.
A Tek 2465 for $66 bucks ..that's scary.... :O


That's a good deal but it's probably very tired even if it works. Usually they go for around $300-$500 US. But be prepared that the knobs fall apart. Last time the delay trigger clutch fell apart on me, major dismantling required. But worth it. These were IMHO among the best mainstream scopes Tek ever made. Unlike the TDS series from which I personally stay away after some nasty noise issues. Plus they've got no memory to speak of. 2.5K, pathetic. They should hire some of their retirees back, they know how it's done.

I bought a GW-Instek GDS-2204 a few months ago. So far very happy with it. Plus it got ten times the memory depth of the more expensive TDS, 25K. Heck, even HP only had 4K. Bought it from Farnell UK via Newark, IIRC a tad over $1600 with customs, shipping and taxes. I could look it up if needed.

Probably the best for both worlds would be the Hameg Combo-Scope HM2008. Has a real CRT and I think a whopping megabyte of memory. However, it'll be somewhat above your budget now because the Euro is so high.

Some scopes have a small logic analyzer with eight or so probes built in. Very handy if you have to debug an extended SPI and stuff like that. I do that with the four channels and a dousing rod, or a real logic analyzer but mine is too heavy to carry to clients.
