The test pattern needs to be defined.
Timing location for pk-to-pk and mode measurements.

Mike to update 07-001 to include actual measurements and indication of how calculate with both positive and negative traces.
Kevin Witt to also update his proposal with a mode measurement rather than small window intervals.
Bryan Kantack and Alvin Cox to write a description of the mode value for the specification based on the decided-upon measurement method.
