A $360 SDG1032X would fix that and still beat a MSO5k budget. |

Or segmented capture in their lower priced models. --- End quote --- Maybe not everybody needs it. I can't say I've missed having it since I traded in my Rigol. :-// --- End quote --- Agreed. I rather have good decoding and deep memory always on instead of segmented recording and statistics. Edit: as has been written before: in the lower end there will be comprises to be made; there is no perfect scope that does all. |

Re: The AD2. Just to be 100% clear: The AD2 is NOT a great oscilloscope, it will never replace a bench oscilloscope. What it IS is a general purpose electronics tool, it does all sorts of clever/useful things. It might help to think of it as a "Swiss Army Knife" - they're not the greatest knife in the world but they have all sorts of other tools like screwdrivers and scissors and saws. Check out all the modules here: https://digilent.com/shop/software/digilent-waveforms/ Edit: It looks like they forgot the curve tracer... --- Quote from: 2N3055 on October 03, 2022, 09:37:37 pm ---What is actual performance of it performing stability analysis on a switcher PSU? Dynamic range and complete amplitude range? How well it performs in presence of noise? I searched and found no real performance figures in real world scenarios ..what is real performance of AD2? --- End quote --- That's completely the wrong way to think about the AD2. --- Quote from: 2N3055 on October 03, 2022, 09:37:37 pm ---I know it has Bode plot functionality but despite it's nominal 14bit resolution, it has only 2 measurement ranges. --- End quote --- Yep. 5V and 20V ranges. If you're doing Bode Plots at 100mV (or above) then it'll work just fine. (maybe even at 50mV). |

--- Quote from: Fungus on October 03, 2022, 08:44:04 pm --- nb. You don't get any more pixels. It's just the 'scope's screen scaled to a window. --- End quote --- I suspected that. It can still be useful, but I was aiming for a glorious 4K, 27" representation of my signals. --- Quote from: Fungus on October 03, 2022, 08:44:04 pm --- With a USB 'scope (or Analog Discovery) you actually get more information on screen when you make the window bigger. HDMI capture for a PC can be had very cheaply. https://www.aliexpress.com/wholesale?SearchText=hdmi+capture+usb I'm not sure I'd give up a touch screen interface on the 'scope just to have remote access from a PC. --- End quote --- Would you recommend some usb scopes with good software? I know that the AD2 is good for the price, but it's just 30 Mhz. Which, with the 5X, means that you get to observe signals, accurately, up to just 6 MHz. The Picoscopes are expensive as hell (I could get the 70 MHz maximum, at ~850 eur) , and the software doesn't appear to be so great. Thanks for the tip about hdmi capture, I didn't know that! |
