Finally mine arrived.
As somebody asked, here is a short review.
Overall verdict: I have an overwhelming experience. So far I don't have any plans to sell it or return.
0) I'm shocked, it looks like it can capture all 14M points (full memory depth) at full 1GSa. How is this possible?? I thought there should a "fast" and a "slow" memory for different acquisition speeds. What a nice surprise, I can capture whole 10ms at full speed and zoom-in up to some ns per division.
1) Usability. I highly recommend go try by yourself and see what's really important personally for you, and what is not. I'm personally happy with the usability, it's 4+ out of 5. On the good side: it has good responsiveness for most functions it does, better than (ta-da!) RTB2004. Display is bright, knobs are fine.
2) Bugs. There are some. What I found is that horizontal cursors do not account for probe attenuation. Also frequency is displayed wrong when I enable low-pass filter on trigger (shows 1MHz on a 40MHz sine). May this thing somehow counts frequency with the trigger?
3) FFT. I never had a proper a proper spectrum analyzer, but it doesn't look like this scope can replace one. Functions I miss: measurements and quick navigation between peaks. A bit disappointing. But I'll try to write a software to do this (just for fun).
4) Fan noise. Quite noisy in my quiet room. It's not a mechanical noise, it sound like an air conditioner (or like air flow is blocked, I need to re-watch tear-down to see if this is the case)
5) Probes. They look okay, I also bought Testec TT-HF-212 just in case (and for comparison), but it needs a 1MHz signal for proper calibration. Now I need to figure if my SDG2042X (I bought it as well) is good-enough for "three-point probe calibration" and what sort of adapters needed. Huh, silly me
I still keep playing with it, discovering, doing stupid stuff (like "measuring" capacitors, playing with cable termination, etc). So, if someone still wants, I can write and update after a while. I really want to find a way to download waveforms to PC (Linux) and control it remotely for automated measurements.
PS never had a scope before (except DSO138, google it if you never seen it). My previous experience was with DSO1052, and before that some old analog scope that had only external triggering (or may be I was too stupid not to find it).
PPS I'm not an electronics engineer, not at all.
