a In the oscilloscope Timebase menu, select Scale: 1.000 ns/div.
b In the oscilloscope Timebase menu, select Position. Using the
oscilloscope knob, position the data waveform so that the waveform is
centered on the screen.
c On the oscilloscope, select [Shift] + width: channel 1, then select
[Enter] to display the data signal pulse width (+ width(1)).
d If the pulse width is outside the limits, adjust the pulse generator
channel 2 width until the pulse width is within limits.
