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?
