Reply to "Design of a $10-20 DCS-TIU Port Tester Tool?"

Truthfully Joe, the tool was originally designed to simply measure the open loop signal on the TIU channel with nothing attached. Any mention of "track" in the picture will negate any calibration as every layout is going to present a different load to the DCS signal frequencies.
Remember, this is a DCS-TIU Port Tester Tool.

GRJ is right, the track loading will make the tool act funny. You "could" do this with an elaborate before and after scheme. Like if you connect the track, then calibrate, and just leave it there for all time.
