Well, the Picoscope which has comparable spec to the Hantek is 160 USD... Cheers Klaus

Really? Which one is that? Which Pico model and which Hantek model? -- Rick

Let me rewind it to your claim of 1000USD for a Picoscope: http://www.picotech.com/entry-level-oscilloscopes.html Picoscope 2200A, 50MHz, 460USD Compared to Hantek DSO5062B: http://www.circuitspecialists.com/digital-storage-oscilloscope-dso5062b.html The Picoscope has an arbitrary signal generator, the Hantek does not Cheers Klaus

I don't know if you saw my post on TekScopes, but I actually replaced your panel with a different one ( http://www.ke5fx.com/tds694_lcd2.jpg ). The image quality was fine before, but matching the scope's native 640x480 resolution made it look even better.
Glad you're happy with it. I did see your thread about that on Tekscopes. I bookmarked the LCD you used for future reference. I still have one left of the panel I put in your scope; when I need more I'll probably buy the one you used as long as it's going in a higher-end unit, as it is more expensive and the margins on the lower-end models has become quite thin. The one I've been using is this one: http://www.ebay.com/itm/360725515609 It's half the cost for some reason...

I hate scopes that don't have separate controls for vertical amplitude and position. (But I'll sell them till the cows come home...)

The manufacturer says it costs 9k6$, not 3... Best regards, Piotr

Sure. It's a better scope, for less money, than the Keygilent. A $350 Rigol is all the oscilloscope that most people ever need.

Ok, that's great, but not what I was comparing because I am looking for a MSO. That is why the Pico weighs in at $1000. -- Rick

Have you looked at LeCroy. I haven't used one since the old orange trace ones. The new ones look nice and have a lot of features. The low end WaveSurfer 3000 Oscilloscopes run about 3K.
