g. Check against limits: CHECK that the cursor readout on screen is
≤
250 ps.
h. If the channel skew is within the limits, enter the time on the test record
and proceed to step 3. Otherwise, proceed with steps i through p.
i. Use the cursors to measure the skew from CH1 to CH2, CH1 to CH3,
and CH1 to CH4. Write down these three numbers in the first measure-
ment column of Table 1–5. Note that these numbers may be either
positive or negative.
j. Repeat the procedure from step 1.c through 2.e.
k. Again use the cursors to measure the skew from CH1 to CH2, CH1 to
CH3, and CH1 to CH4. Write down these numbers in the second
measurement column of Table 1–5. Note that these numbers may be
either positive or negative.
