Figure 6-4 , Figure 6-5, and Figure 6-6 show eye diagrams at BERT source output, through calibration traces, and through 810 respectively. Note: 810 adds little to no random jitter. Residual equalization of ≅4 dB at EQ = 0 setting results in slightly lower deterministic jitter through DUT compared to baseline setup with 7 dB loss.
