Oh yeah. I have the same problem. And as EVERY 20th male is effected, I am wondering for years why nobody ever had the idea of allowing a user defined color for each channel (even a selection list with just 16 entries would be fine). A scope with such a feature would have indeed a BIG USP!!!
For colorblind people, would it work if instead of using different colors for the traces the scope would use different 'pen styles', like continuous line, dotted, dashed, etc. ?
That would be useful also for non-colorblind people with screen hard-copies on colorblind b/w printers.
That would be too much work load for the display routines and it would slow down the scope. However, most color blind people are having a 'only' a red/green weakness - with all nuances.
And it differs how large an object is and what the shade (color mix / brightness) is. E.g. I cannot recognize a small red object on green gras. I should be lucky, that I am not a bird: I would not be able to find the red berries in a hedge from the distance and would starve to death. Only if I get close enough I am able to realize them. Two 10" papers one pure red and one pure green in front of me are easy to differentiate. A traffic light in front of me is easy - 200 meters away I cannot tell you for sure if it shows red or green - but the brightness for me is usually a good indicator). Same with LEDs: I cannot tell if a LED is red, yellow or green (this is why I HATE this duo-LEDs). If they are side by side I can see a difference, but with a single LED is impossible for me to see if it is red or yellow or green. The lane assist in my car uses a duo LED to show if it is active or now - I cannot see the difference. Now if the manufacturer at least would have made red (or green) a bit brighter or darker I would be able to recognize the difference - but they did not
And indeed on my MSOX3000 I used channel 1+3. However, I did purchase a 4 channel scope, as I often need 3 or 4 channels.
Thus: if a scope would offer the possibility to have a userdefined color for each channel, anybody would be able to select his favourites which would be the easiest to recognize/differentiate for him. It would be no big deal to add this to the software (as I said, a set of 16 different colors would be enough - so no 16 million RGB selector is needed).
So developers listen: If somebody is interested, I would be glad to provide RGB colors which are easy to recognize / differentiate for the 5% men with a red/green weakness.But this has nothing to do with the R&S scope, so lets close this discussion here and focus on the RTB2000 scope.
