5:55 Notice the ferrite bead on the big beefy diode. (Which Dave actually pointed out later. Just scribbliong down thoughts as the video goes along.) Might have something to do with ringing from when the diode switches. A novel replacement for snubber caps?

23:55 I don't like the placement of that crystal. Seems like an IDC connector might apply pressure to it. Would be easy to move it a couple of mm in the other direction, methinks.

27:10 Not digging what your LED lights are doing for the videos, I must say. Maybe you can diffuse the LED strip somehow?

32:52 Sexy spring loaded knobs, eh? Ms EEVBlog: "How COULD you do that to me? What does that scope have that I don't?"

35:10 Does that flat flex split and go both to the LCD and secondary button board?
Whoa! How the hell did Dave know that Bob is my uncle? Amazing!

I wish I knew these existed before I bought a DG1102 a few months ago.

I laid down the cash for a DS2072 about foru weeks ago, very happy with it. Feel even better about it now.

Now , if I can just find away to turn those options on & turn up the bandwidth ..............

6.3V is a standard heater voltage, but that is AC. For DC heater supplies it's common to use slightly less.

looks like Rigol like your work too Dave. They already have a link to your video on their site.

I suspect these video links are auto-generated some how.

Dave, if you can't find some old diffuser from a fluoro panel to cut up, this may be of use to diffuse your led panel lighting so it doesn't affect your videos

I picked up a DS2102 and have definitely been enjoying it. I'm looking forward to Dave's look at the UI/functionality. There are certainly a few quirks in it.

I noticed that the one being reviewed didn't flash the 36 hour demo screen. Its promising that the sample memory depth is software set (up to 54 Mpts).

6.3V will have been used to clear the dropout voltage for the 1117 LDOs down to 5V.

I just need to add a remote switch to turn it off and on whenever I have a reflective item like a screen. A diffuser helps, but you'd still get the ugly glare all over the screen from the light directly above.
MY teardown bench has two troff lights either side of it (not directly above), and now two LED strips going the full length.

Thanks Dave for the teardown... I love my DS2072 tooo much to want to open it up.
One thing I noticed, when you turned the scope on the "welcome" screen with the remaining time for the addons didn't appear,
Is this a demo scope?? or did u pay the extra for them...???
Can't wait to see your review of the UI...
Keep up the good work :)

It seems to be fully optioned up, no time limit on the info screen.
Rigol US gave it to me, I didn't buy it. No idea if it's factory new or a demo unit, like I know the DS815 and function gen were.
I believe all new shipped units come pre-loaded with the trial licenses? To get you used to it, and suck you in. Clever  :)

I've seen those through hole metal loops fail on PC motherboards too. There's quite a bit of force on them.

Dave, is the fan a crappy one (noisy) as in the DS1052 or have the opted for a quiet fan ?

what's that metal tab poking out in the bottom right corner? security tie-down point?

I did't notice it much, so I guess it's better.
Have not done a direct comparison though. It appears to be temp controlled.

Slightly cheaper but definitely not chinese crap, noisy but high reliability. Industrial fans are like that

Take a gamble, you could even do a teardown for laughs. These things are so cheap I might consider sending one for a mailbag...
DS1102E?
Yeah, that's what I meant. Thankfully it was only $400 and came with a nifty bag, but I think the 2000 series is worth it just for the screen.

Already had one, now installed. I can now switch the two 3m long 20W LED strip lights above the bench off and on as required for each shot.
I can also RF remote control the two 60W 1200mm x 300mm LED panels that now fill the corner of the lab in front of me (facing camera), and also greatly help to light the bench as well.

Video rendering now on the LED panels, + another one on the LED strip installation coming, and another one of me installing the LED panels in the roof.
+ tons of theory with Doug + something goes bang!

I was gonna buy a IR switch too, a WALL mounted one  :P Well, 800$ is plenty good enough for the fast screen and the deep memory is worth another 800$ ... 14Mpts not sure how much to "upgrade" the other 42MB DDRII but there will be hacks soon enough  :P

So the big question, has anyone hacked this yet to get the full memory?

Interestingly, it seems that Rigol do not offer a software bandwidth upgrade option. Factory only?

And I think I just realised why it's only 56MB instead of the 64MB chip available - the scope has a waveform record/playback option that can store thousands of waveform. So that's gotta take up that sample memory. Have not confirmed this though.

Maybe they do not, in order not to encourage hacking...
Fact is that the extra memory is already there, probably awaiting to be utilised.

I guess that only a thorough Blackfin firmware disassembly can positively answer that. But who's got the time for that?
