5.2.1 Measurement vs. Simulation Correlation (connector only)
Figure 101 and Figure 102 show the measurement vs. simulation correlation of insertion loss
(IL), return loss (RL) and differential S parameters (SDD) between two nearest neighboring pairs
for the center differential pair 8 (as shown in Figure 100). Good correlation was observed for all IL,
RL, near-end cross-talk (NEXT), and far-end cross-talk (FEXT).
Figure 100 Differential NEXT and FEXT for center pair 8 were measured for 8 surrounding neighbors
