Normally, a 2-port calibration requires a forward and reverse sweep to Cnish before updating
the displayed trace. For faster tuning, it is possible to set the number of sweeps for the
active display (Sll and S21 for channel 1 in this case) to update more often than the unused
parameters. In this example we choose 8 updates of the forward parameters to 1 update of the
reverse in channel 1, and 8 updates of the reverse to 1 update of the forward in channel 2
(where the active parameters are S22 and S12).
