Bests & Worsts Reviews from Amazon

I had a nearly 30 year old surplus Tektronix 475, 200 MHz dual channel scope that died a year ago. I had opened it and tried to fix it to no avail. At some point it became clear if we fixed it, we'd spend about as much as buying this Siglent scope we'd still have a 30 year old scope that could die at any minute, and we decided to get a modern digital scope. I did a lot of research online between the Rigol, this and others, and went with this one. I've fixed several things and tested the scope with a good signal generator and find it's a very solid performer. Remember, 200 MHz in a scope means 3 dB down, not that you can't see higher frequencies, so I tested it at 500 MHz. I was easily able to observe a signal from my generator, although the amplitude displayed was lower. That's fine for some levels of troubleshooting. Yeah, it doesn't do some things as well as my old 475, notably I haven't gotten it to show an AM modulated envelope properly, but it runs rings around the Tek on other things: single event sweeps, stacking many traces, and (of course) saving screen captures to a thumb drive. And to be honest, I don't look at AM all that often to care much. I especially like that it weighs nothing compared to the Tek and I can carry it around the house to whatever I need to look at.
