100 Advanced - Lanes Mapping & Skew
RX
Skew (bits) indicates the delay in bit time between the earliest
PCS/Logical lane and the current lane for the one to zero transition of
the alignment marker sync bits. The received skew accuracy is
±100 bits.
PCS/Logical Lane indicates received PCS/Logical Lane markers.
Note: If a PCS/Logical Lane marker is detected more than once, a red
background is used to highlight all occurrences of this PCS/Logical Lane
marker. Duplicate is also displayed on a red background.
PCS/Logical Lane
Allows ordering the PCS/Logical Lane markers in either Ascending
(1,2,3...) or Coupled to RX.
