I’m using Logic 8 with software 1.2.18 on Linux . Sometimes, I see different results for analog and digital representations of the same channel. Here’s an example. The pulses appear of equal length in Analog, but the high pulses are longer than low in digital. Same channel.
Another issue that’s been coming up is a kind of glitch, or a piece of noise. This screenshot is a zoom into the same capture as above. The analog is smooth at 0V, but the digital shows a 10ns (one-sample) dip.
I assume that analog is the more accurate in this case, mostly because it shows what I want to see :=) Seriously, though, looking at the capture, I can’t tell if my DUT is generating correct signals and Logic displays them funny, or if the DUT is glitching.
