The outputs of data lanes are directly connected to the DSO inputs via
SMA connectors. The skew is measured for all DUT lanes with respect to
Lane 0. For Lane 1, the skew between Lane 0 and 1 is given as:
Skew = mean ((Lane 1 crossing times) - (Lane 0 crossing times))
(L1-to-L0)
The skew is measured and calibrated iteratively until its value is smaller
than the specification conformance limit.
