low-end scope
in [Design]
|
From: John Larkin on 1 Mar 2010 13:34 I'd like to have a low-end scope or two to keep around the house, occasional use only. I could use it at work, too, for simple analog stuff, timing software execution, stuff like that. I was think about a Rigol DS1052E, 50 MHz color, 2 traces, about $535. Or something like that. Any suggestions or comments? John

Could be the GDS-1062 which they got instead of a 1042, don't remember but if you want me to I can ask them. This thing has really impressed them, especially the PC connectivity (they are heavily into LabView, MatLab and Excel). Hint: I bought their flagship at Newark because it was the best price. On the smaller budget models Newark is often not the best deal, they ended up buying at some other place. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

With the price of net-book type PC's as low as it is, a separate PC just for test equipment use might be economical. -- Virg Wall, P.E.

I'd rather not have a scope that runs Windows and that needs two boxes, drivers, a USB cable, and a mouse to do anything. A real scope will most likely still be working 20 years from now. I like real scopes with lots of real knobs. A USB scope would make sense in some data-centric application where the waveform needs to be shipped into Matlab or some such in real time. John

Any suggestions or comments? AFAIK this has 4 ADCs in multi-phase clocking. I wonder what that does to jitter and resulting sampling noise. Screen resolution is also a bit low. -- Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico(a)nctdevpuntnl (punt=.) -------------------------------------------------------------- |
