inconsistent results between digital and analog on 2204MSO

Post by shwouchk »

I posted a more detailed post earlier but I don't see it, so hopefully I forgot to press "Submit". Nevertheless, I'll make it shorter.

Measuring a UART pin that is communicating at a known baud of 115200 with analog probe as well as digital pins simultaneously. The analog probe measures roughly consistent with known baud. The digital shows weird drops (those continue elsewhere, such that e.g. the serial protocol decoder thinks the baud rate is ~1Mhz).

What's going on?!

Thanks!

I would suggest posting the psdata file associated with this so that we can look at the settings in more detail.
