The app menu i found it pretty ridiculous: it's not a computer nor a cell phone...
Too many errors in the oscilloscope.
There's no fast forward button in YouTube. I wish there was.
I believe I've figured out what the problem is with the intensity grading on the Instek:
Even before Dave's video, I had found it rather strange when looking through the specifications that GW-Instek doesn't specify ANYWHERE how many levels of gradation they do.
Agilent specifies 64 levels - Rigol specifies up to 256 levels - but Instek just says 'multiple'. Well, I analyzed EVERY uncompressed screenshot posted online that I could find from the GDS-2000A - and it appears the reason the grading looks bad (both intensity AND color) is because they're using a maximum of 16 LEVELS of grading (or 16 different colors simultaneously). This would also, of course, help them achieve faster wfrm/s rates.
The attached image shows a Rigol screenshot with 54 levels compared to two screenshots from the Instek with 12 and 15 respectively.
Now if this is incorrect, and it's possible to to adjust the Instek for a finer gradation, I'd like to know about it. But so far, the evidence suggests otherwise.

i don't think you can speed up data capture by reducing grading depth, DPO-core will simply add data and run next capture, display processor will count
depth value and calculate color/grading.
and the sig-gen is really crap, basic wave-forms, if you want two outputs, then buy to add-ons, and can't use any other add-on, and almost 3K is a lot of money for such a basic product.
Now that is DUMB..
Two BNC's in the front for what?
If they both perform the same what is the advantage, being able to swap to BNC 1 or BNC 2, now that is really dumb..
Until someone does a more comprehensive (and perhaps objective) measurement of it's waveform update rates, this is the only thing we have at the moment (from the Trigger out signal). I'd like to see my 'either' Edge trigger method used to test it.
OK, but who created that table?
Why?
The trigger out is the ultimate method, unless you think the Instek's trigger out is faulty? The max value matches their quoted figure.
the trigger out voltage is quite low
That's bad, because there is no problem with measuring Trig Out of DSOX2002A or your DS2072 with a common multimeter (with counter). A normal scope has a proper output level.
