50 ohm termination to ground located in each scope channel input.
All input and output cables to the scope are equal lengths of 50 ohm
coaxial cable. Wire length should be < 1/4 inch from TPin to input pin
and TPout to output pin.
Note: All power supply and logic levels are shown shifted 2.0V positive.
