Switch matrix connections: When using a switch matrix that is equipped with triax connectors,
separate HI-to-LO matrix paths are required for the pulse generator. A typical connection scheme for
this type of switch matrix is shown below. As shown, OUTPUT 1(HI) is connected to a matrix row, and
the return path (LO) from the switch matrix is connected to the ground unit (GNDU). Note that in order
to complete the return path, a separate cable connection from the GNDU to the chassis of the pulse
generator is required. Remember, the chassis of the pulse generator is output LO.
