Modifications to shunt placement.

Added some images/documents of the board schematics, layout, etc.

added fabrication plots and compressed.

reworked the whole board so the grounds are properly isolated and can be connected to a common star ground offboard. No vias are necessary for routing, either, which is a good thing for signal integrity.

Reworked the isolation and grounding scheme, added two shunt resistors and two connectors for each.

Merge

Added some images of the schematics and a compressed file for sending to fabrication house.

Added some changes to the awg-tx-cal-box.pro

Added power amp schematic project

Added pdf plots of the AWG to TX/shunt board.
