Precautions when connecting digital inputs
To avoid crosstalk on the digital inputs when probing signals with very fast edges,
please take extra care with the leads in the digital input cable:
Keep any leads carrying fast signals separated from the other leads.
Keep the leads carrying fast signals as close as possible to the ground leads.
Connect all four black ground leads to the ground of the circuit under test.
