Installing and Configuring
the SCXI-1129
The SCXI-1129 is a 256 crosspoint high-density matrix module. It provides
up to a 4
×
64, 2-wire switch matrix configuration on an SCXI platform.
The SCXI-1129 can also operate as four 4
×
16, 2-wire matrixes;
two 4
×
32, 2-wire matrixes; or two 8
× 1
6, 2-wire matrixes.
Note
Common matrix terminology describes matrixes by the number of rows by the
number of columns they contain. For example, four rows by 16 columns would be written
as 4
×
16.
Through the use of special terminal blocks (refer to Table 2-1,
), the SCXI-1129 can become many different
matrix types. Refer to Table 1-1 for a complete list of matrix
configurations.
To accommodate even larger testing needs, you can expand the matrix size
by combining additional modules. With the use of terminal blocks, you can
expand rows on the 4
×
16 and 16
×
16 matrixes, and you can expand rows
and columns on the 4
×
64 and the 8
×
32 matrixes. These modules support
the analog bus through a special adapter, the high-voltage analog bus
(HVAB) backplane adapter in the SCXI-1357/1358 kit, at the rear of the
module. This adapter allows you to expand the HVAB without complicated
Table 1-1.
