@scale_w weight for "uncertain" values (where samples chane from all 0 to all 1 in one step) Run DQ vs DQS fitting for one data lane (0 or 1) using earlier acquired hard-coded data
@lane byte lane to process
@bin_size bin size for the histograms (should be 5/10/20/40)
@primary_set which of the data edge series to use as leading (other will be trailing by 180)
@data_set_number select one of the hard-coded data sets (sets 0 and 1 use comparing with the data 1 fine step below
set #2 (default) used measurement with previous primary step measurement (will not suffer from
fine range wider than on primary step)
@scale_w weight for "uncertain" values (where samples change from all 0 to all 1 in one step)
For sufficient data 0.0 is OK (and seems to work better)- only "analog" samples are considered
@return 3-element dictionary of ('early','nominal','late'), each being None or a 160-element list,
each element being either None, or a list of 3 best DQ delay values for the DQS delay (some mey be None too)
