Post by: Asellith on June 16, 2008, 01:33:50 PM

Anyone used this before?

Looks good and the price is right but is it work it or should I save my cash and buy a real o-scope?

I've been looking at that one and also the one at HobbyLab (http://www.hobbylab.us/).  I have the same reservations.  The price is right, the bandwidth is low, but I'm not doing any high frequency stuff.  I'd be interested in hearing what others have to say.

I bought an Embest DSO2300 a year or so ago, and even at a cost of $300, it has paid for itself several times over.  Main difference is a sample rate of 100Ms/s.  Only complaint is that there isn't a Linux driver.

I bought one a few weeks back.  It works alright, if abit low in the frequency range but will do for what I need.  The only reason I settled for the USB scope versus buying a used o-scope off Ebay was space.  My work bench has none, and the USB scope takes up next to none.  If I had the space I would have gone with a used o-scope though.
