2. Measure the delay time at any combination of two digital data outputs:
a. Write the delay time read from the oscilloscope screen.
b. Do the step a as changing the cable from the oscilloscope CH2 connector
to Dx to D9.
The Dx means the connector just right to the connector currently
connected to the oscilloscope CH1 connector. For example, if the D4 is
connected to the oscilloscope CH1 connector in step c, Dx will be D5.
c. Do the step a and b for any two digital data outputs as changing the
cable from the oscilloscope CH1 connector to D0 to D8.
3. Check the skew:
a. Find the maximum delay: Find the maximum delay time from the values
measured in step2 .
b. Check the skew: Check that the maximum delay time is equal to or less
than 1 ns.
4. End procedure: Disconnect the oscilloscope.
