The following steps check the rise and fall time accuracies for the clock output
and data outputs on all channels.
9. Using the oscilloscope measurement functions, perform the clock signal rise
and fall time measurements under the low and high voltage level, and rise
and fall time settings indicated in Table B-8, and confirm that the measure-
ment results are within the specified range.
Set the oscilloscope trigger slope to Positive for observing the pulse rising
slope, and to Negative for the pulse falling slope.
