I have read most of the threads and posts on this scope. I must say I am very impressed for the price. I do have some gripes about it already though after only having for a few hours.
#1. I have to agree with some others here; The control response is so slow for some things. Not a deal breaker but I did not expect such slow response.
#2. The menu system and options are a bit intrusive when all you want to do is see the signal.
#3. Measurements displays always display even if the are deleted or cleared. I remember reading about this here but I don't remember any option to just see the measurement display that is actually active without having to shut down the scope and restarting it.
#4. No adjustable filters? The DS1052E has this. Why not the DS1054Z?
All in all I am very happy with my purchase and think this is a great addition to my kit, but I won't soon be selling my DS1052E nor my old analog 20MHz scope. They still have their advantages for some things. I wanted 4 channels, serial decoding, serial protocol triggering output, bigger display, bigger memory, etc so it was a good buy.
