i don't see any problem with color grading implementation, all you need is to set base color (and maybe have way to invert them,
e.g. from blue to red spectrum). This seems to work on GDS-2000A good. The benefit of color grading you need only these
256 colors and not waveform intensity crap (yes, on analog scope there is no color, but hey, wh cares? my TV is color since
40yrs already ...)
Where is maybe (Dave or grego need to test it) something worng is how fast the intensity is
changing when turning the knob, all i saw was Dave turning wild knob to right, to left and back and beeing complained
about the waveform colors
However, for a fraction of second you can see good picture (like in the middle picture of the link below), even with single color.
Check here
http://www.gwinstek.com/vpo/on the bottom the intensity pictures, on Daves video i saw only max or min^^
So when this is an error, then only in way how fast the intensity is changing (and i can clearly see that on Rigol you need to
turn the knob for an hour ^^ to get from min to max).
Lets not read too much into it yet. Let Dave do his tear down and full review.
right, it was first touch only.
