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
In the 4

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
x
to B3COM
x
), you can connect the rows
of the four 4

16 matrixes and the two 4
× 32
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
