Re: Oscilloscopes - what to look for?
- Anyone have any thoughts on this device?
- I haven't seen that 4 channel mini scope that's on Ebay before but it looks pretty sharp and very portable.
I have a Rigol DS1000E and although I prefer the Tektronix models of similar size and capabilities, you can't beat the Rigol's $329 price.
I would recommend it, especially for casual/hobby use.
I don't wish to bend any posting rules so I had better say that I do have a highly modified DX394 (a few years now on this forum) but I also work (near retirement!) on the technical support desk of a UK oscilloscope manufacturer, Pico Technology.
An oscilloscope is useful but not essential for aligning a radio but very useful for repairs & mods. I could recommend a basic model from my company but I won't here, just contact me at "support@..." (attn:- Peter) or on my home email.
What I will do is give you a link to a short tutorial on our website explaining the differences between an older bench scope and PC based scopes as we manufacture. Fairly old now but worth a look!

There also seem to be a lot of lower cost items at around the £200-£250 on eBay where the look and layout of controls is almost identical to items I've seen in Maplin for £400-£500. Then there are lower cost items like the DS203 NANO or older CRT and computer connected scopes.

I think I would prefer to stay independent of the computer but would conbsider this option if ot works as well as a 'real' scope. My budget is probably up to £250. Since space is at a premium, a built in signal generator would do nicely, but that is only a secondary consideration.
