7.2 Crosstalk

The setup for crosstalk measurements in a 50

 NWA system for several pin

combinations reflecting the various possible physical distances is shown in Figure 5.

The crosstalk measurement results are depicted in Figure 6. Other combinations behave

similar, depending on the distance between the pins.
