Identification of channels and associated signal information contributing to a portion of a composite eye diagram |
摘要 |
An eye diagram analyzer can assign a plurality of SUT data signals to be members of a labeled group of channels. There may be a plurality of such groups. The measured data for components within a group can be merged according to various different modes into a composite eye diagram presentation. When a composite eye diagram is being displayed, the operator may position a screen pointer (cursor) over some interesting part of the eye diagram, and the analyzer will display a list those channels that contributed to the displayed pixels in that part of the eye diagram, as well as other related information. The operator may also select a channel from among the group, and then have the displayed pixels for which it is responsible be displayed in a selected color or otherwise highlighted in a way that allows them to be distinguished from all others.
