Economical Oscilloscope?

[LourensKoopmans]

I recently acquired an dso nano at :
http://www.seeedstudio.com/depot/dso-nano-preorder-p-611.html?cPath=11

It is usable for audio measurements..but has limited bandwith..is single channel..
But only $89.00



I upgraded it with Pauls firmware from:

This firmware allows calibration of all vertical multiplication factors..i compared it with a calibrated oscilloscope at work..

Use the Winscope free program.

Single Tektronix 2225 is for me of my oscilloscopes. Better than this is not needed at all.
Is for me a Velleman pc500 oscilloscopes.
But analogue Tek the real one for me.
You need to buy an used Tek analogue scope and thats it is.

Picked up a Tek 2235 off e-bay. Works pretty well, but I still preferred the old 465's.
Cheap scopes, and I have had Heath, Hitachi, and Ramsey, are not worth the frustration. That is why a cheapskate like me bought a used Tek. Tek, HP, maybe Phillips.

I have an old IG-18 and with an upgraded power supply. The big low distortion mod was never stable, so it has the original board back in it. Also a couple of Heath VTVM's. The Heath AC VTVM is actually just as accurate as my HP. Don't use the Heath generator as I bought a HP 209. PM me if anyone is interested in it cheap. I like the sweep rather than step for speaker testing. For low distortion, I use PC based generators in my spectrum analyzers.

Zelscope seems to be the best PC based scope without a custom module. Still frustrating, which is why I bought the Tek.

I am about to build my first Amp (Naim Clone) and I wonder if this little scope is suitable for measurements on an Amp like voltage ripple etc.?
Not ready to buy a proper analoge scope so this would be a perfect starter..

Svein, you have GOT to tell me where to get a 'scope in Norway for under a million, trillion Kroner

Now, all concerns aside, how good is that DSO Nano, with it's limited bandwidth and screen resolution?

Thanks

A student scope is good enough - look for a college equipment auction or recycle center. ~$50-80 for a 2 channel 20-40MHz scope, probably leader or some off brand, but probably quite serviceable. Don't buy if you can't turn it on and at least see a trace....

I can't say DITTO strongly enough. A 502A or 56x series will do you forever.. and they'll run that long, too. Personally, I think the 502A is the best audio scope with its differential inputs, high gain and amazingly sharp screen. Use the high contrast green filter, too.
