How to use this Section

This Section shows how to identify channels' area of influence associated with certain probes, and
transmit and receive boards within the Cardrack. By looking at the missing channels area, you can
identify the boards associated with that channel and determine possible origin of a particular artifact.
Colors are used to identify the components and the "region" within the near field are bordered in the
same color (as the respective component). Within this "region" is where an artifact will appear.
The guide lines in the overlays represent an approximate border between components. When an artifact
is seen near the border between two components, both components should be considered.
