content: Hello everyone. I've found many of the archives here very helpful, but I could sure use some personal advice at this point on a first oscilloscope purchase.-My main interests right now are general analog electronics, motor control, switching power supply circuits, and microcontrollers (mostly 8/16 bit PIC's).-I want a scope that is satisfying to use, has solid controls & build, responds quickly, and generally behaves as much as possible like a classic analog scope. (A old used analog isn't a good option for me due to size and my current inability to diagnose and repair any problems that might show up).-While serial decoding would be a major plus, I'm not counting on it.-I'm wary of the Rigol 1000Z because it looks like 4 channels would be awkward to use on such a small scope with such limited sampling. I'm also concerned that it has no competitors in its price range.I was originally planning to get the popular Rigol 2072A--the controls look good and the big display is a major attraction.However the Keysight DSOX1102A is very attractive, particularly due to the comments on the fast response and dedicated ASIC design. I wish the display were the size of the Rigol's.I'm also tempted by the Rohde & Schwarz HMO1002 Max package from TE. It certainly looks good from the EEVblog videos.I'd be very grateful for any advice from people who've used any or all of those scopes, or for any corrections if I'm missing something.Thanks.

content: You sure solved my problem fast!You found *exactly* what I really wanted at exactly the right time. (That's hard to do with ebay!)Thanks again!(Thought it was too good to be true at first but everything looks good.)

content: I am glad you found the scope you were looking for. I was following it for some time, but could not find the justification to buy another scope (I already have 3)

content: Why only look at a 2 channel scope? With motor control, microcontrollers, etc I'd definitely go for a 4 channel oscilloscope.

content: Quote from: nctnico on May 16, 2017, 09:25:05 amFour channels would be great...but I can't afford it right now. If you want more than a Rigol 1000Z you wind up in the $2000 range very quickly.However if those hacks for the one I bought pan out I'll get 8 extra digital channels.
