Oh, I am still all giddy over my DS1052D. lol. This is the version that comes with the logic probe. I've been wanting an scope ever since I lost access to the tektronics 15 years ago! They were always just so expensive though. All this time I used a simple multimeter and a lot of guesswork to figure out what was going on in my circuits, (hmmm, Is that 2.5 VDC, or 2.5V AC RMS? Who knows! lol) I've done a lot of FPGA, modems, analog and other digital stuff that really needed a scope. I'm still giddy because I no longer have to guess what's going on, a quick probe and it's usually obvious.
Having said that, like some said, it might not be up to snuff of some professionals - especially if they are used to the expensive scopes. For me, it kills the tektronics I had 15 yrs ago, and my simple multimeter, so I'm happy. (which was already prob 10 yrs old!) Of course, you cant compare it to a Tektronics today. (dont get me wrong).
The visual resolution is not large, about 255 pixels vertical. The ADC is also only 8bit...this makes sense since having a 10bit ADC for a 255 pixel vertical image is overkill. I get by with the limited resolution, I still see lots of signal detail.
I love having a logic probe. Having only two analog probes is just not enough in the digital world when you usually need to correlate a bunch of digital signals together.
So far the scope has had an option to handle every type of scenario I needed.
To the person that commented on how long the scanning rate is at higher time scales, did you take into account that the scope stores a lot of signal before and after trigger? So for 5ms/div it stores probably around 72 divisions worth. So in total, about 360 ms. You may be able to change this window so it only stores what the screen can show and that would speed up the scan rate.
I've taken some waveforms off onto the computer. If you take the screenshot it works great (it's just a gif image.) If you take the waveform and use thier software, their software kind of sucks. I made a java program that views it that is better but it's not ready for wide spread release yet. The format of the waveform data is not difficult to figure out and it includes analog and digital channel data.
