The SCXI-1334 and SCXI-1335 terminal blocks also have the ability to
expand columns by connecting rows, as shown in Figure 2-13. With these
two modes of expansion, you can create very large matrixes.
Figure 2-13.
Example of Column and Row Expansion Using SCXI-1335 Modules

32 matrixes, you can to use the HVAB to both
expand the matrix size and connect instruments to DUTs. By connecting
the configuration relays (B0COM

to B3COM

), you can connect the rows
of the four 4

16 matrixes and the two 4

matrixes so that a single

64 matrix is formed. Also, by connecting relays AB0–AB3, you can
connect these rows to the HVAB allowing you to connect instruments
through the SCXI backplane. This connection means that you can use
multiple modules to construct 4
