This graph describes the conditions under which the FS2221 analysis
probe will work most reliably. The total bus length is made up of three
components:
The motherboard etch length
The etch length on the FS2221 interposer card (0.8 inches)
The etch length of the AGP bus on the graphics card
Typical AGP systems will have setup and hold timings which are greater
that the AGP4X bus minimum setup and hold specifications. For example,
with a 1600ps setup and hold time margin, the AGP4X probe will capture
read and write data on a bus where:
the AGP4X connector is 1.55" from the graphics chip
