Ben,
Just my two cents on allowing the reference waveform to be positioned independent of the real time waveform. When debugging serial UARTs, I often send out a reference waveform something like “UUUU” (which is 0x55,0x55,0x55,0x55) at the baud rate I’m using. This gives me a 01010101… pattern showing the bit times. On other scopes, I will position this at the top of the screen as a reference and then I can compare it to the real time serial data. It makes it very easy to count long strings of 0’s and 1’s when you have an alternating bit pattern at the same baud rate to use as a reference.
This can still be done if they overlap, but it would be nice in this case (and in general for all digital signals) to have the ability place one above or below the other like you see on a typical scope with digital channels or a logic analyzer.
It may be more trouble than its worth, or clutter the menu etc. … your call. I read earlier that you like real world example/needs to be articulated, so I just thought I would weigh in on the topic with one that I run into quite a bit.
Best,
Dave
