“What is interesting is that these steps are in the same time domain as the switching noise of the interlace mode. This may indicate that display issues are causing these steps in the interleave mode, and not the interleave mode itself”
I think these steps are simply the sample steps. I notice you have both chA and chB on so the unit is not interleaving two sets of samples. To see the interleaving effect, you have to “HIDE” chB. Then you will see the sawtooth effect discussed elsewhere and you will notice an apparent doubling of timebase rate. (which I consider advantageous)
Also apparent on jpg 4 is poor risetime and rounding due to the effect of excessive compensation capacitors discussed earlier. After adjusting my values, I acheive a risetime within 2 sample periods for a 3.5MHz waveform of this amplitude. Go on Lygra, get you soldering iron in the back there!
