INSERTION LOSS OF THE THROUGH CALIBRATION PATH
To calibrate board trace losses, a through calibration path is
provided between the J6 and J5 connectors. J6 and J5 must be
populated with 2.92 mm (K) connectors to use the through
calibration path. Figure 3 shows the insertion loss, input return
loss, and output return loss of the through calibration path.
Table 2 lists the insertion loss of the through calibration path vs.
frequency.
