4x4 Matrix

This configuration has two independent 4x4 matrices ranging from Bank0 to
Bank1, each with four rows and four columns. The following diagram
illustrates the PXI-7931 with the TB-6231 to produce relative paths

Figure 10: 4x4 Matrix (I)

To use a 2x16 matrix, short the following 16 TB-6231 pads.

The grid below shows the names used for software configuration with
corresponding traces to the TB-6231
