Composite eye diagrams

摘要: An eye diagram analyzer assigns a plurality of SUT data signals to be members labeled group channels. There may such groups. In addition mere superposition in an (X, Y) display space the various i-many Y)-valued pixels for individual component diagrams associated with that group, other measured those within can merged different modes produce corresponding composite presentations. E.g., Normalized Signal Density Mode number hits at each trial measurement point is summed over all channels and then divided by total clock cycles i th density D pixel: (X , Y ). If rendered as color or intensity, resulting includes representation (the ) normalized transitions ), relative whole. As further example, Channel Mode, produced accumulating, N-many channels, 1/N sample (value i) non-zero signal activity, dividing accumulation N. collection degree coincidence among, similarity between, group.
