Analog Discovery 2 Scope slow convergence to final value

Question

The analog discovery 2 has a strange slow convergence to a final value. The actual waveform attached is about correct, except the transitions are going 90% then slowly converge to 100% of the expected value over a period of 200us. If I place a distinct scope (tektronix, keysight) on the same traces, the transition is sharp and no slow convergence to final value is observed. I do not have a 5VDC connected to the Analog Discovery 2, and the grounds are connected between the board under test and the AD2. The scope probes are in DC mode. I tried different options and couldn't locate one that solves this problem. Any idea?

Hi @Alain Gravel,

I have moved your question to a more appropriate section of the forum where the creator of the WaveForms software will be able to see and respond to your question with much more accuracy and detail.

Thanks,
JColvin
