I captured a UART (async serial) signal on a channel (both digital and analog) and noticed some noise in the analog signal that is affecting the digital signal (showing it being high when it should be low). Is there a way to modify the capture file and alter the analog signal, then recreate the digital signal with the new analog (i.e., re-do analog to digital conversion)?
Not sure which of these details are important, but I’ll include them here anyway:
@afok Sorry for quite a late reply! Several of us were out due to the holidays.
Unfortunately, recreating a digital signal from an analog recording is currently not possible, though it’s a highly requested feature. I’ve provided a link below to the feature request post we are tracking for this in case you wanted to add your vote to it. We also don’t have a way of modifying a previously recorded analog signal.
You may be able to clean up your digital signal by enabling a software glitch filter, though you’ll need to start a new recording to have the glitch filter settings be applied, since glitch filters cannot be retroactively added to previously recorded captures.
