3.2.5 Digital inputs on MSO models

The digital input pins of the 20-pin IDC header plug are shown below. The diagram is drawn as you look at the

front panel of the oscilloscope.

To avoid crosstalk on the digital inputs when probing signals with very fast edges, always take extra care to:

Keep leads carrying fast signals separate from other input leads.

Keep 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.
