The average sample position for the data lines during these read bursts is –2.25ns. This Eye Finder measurement was taken with a read delay line setting of 1.8ns. You now have enough information to calculate what an optimal read delay setting would be to capture both read and write bursts. Proceed to Step 4 to do this.
