An update to the 5012H, sent into the mailbag.

Teardown
Claims 110MHz, but again only a dual 100Msps converter the MXT2088

Any better than 50mV/div sensitivity on this one ?

They switched to ST micro instead of GD. So they are probably not overclocking it. Probably don't need to with external memory.

But generally, I would assume it has the same crap performance as the old one.

Seems to. Still wobbly performance on anythign over like 20MHz or so. They are equivalent time sampling again  :palm:

In the video I think Dave had the trigger point (T) all the way to the right in the display when doing the high frequency measurement ( see video at 38.53 https://youtu.be/QKdLP1cP3Dg?t=2333 ), not sure if that was on purpose but it could explain the jittery-buggery going on. I'm guessing this device does not have a good base oscillator.

Best regards
