Overview
Multiplexer
The National Instruments PXI-2530 and SCXI-1130 are high-density, You can configure the PXI-2530 and SCXI-1130 in several different
multiconfiguration multiplexer/matrix switches. With 14 possible multiplexer configurations. The 1 and 2-wire modes are designed for
configurations and multiple expansion options, these modules offer measuring/sourcing voltage or 2-wire resistance measurements.

You can connect the rows and columns of multiple modules to
expand an NI matrix system and meet the needs of high-channel-
count systems. With the SCXI-1130, you can use expansion cables
and plugs to externally connect the rows and columns of the matrix
modules. For example, to create a 4x128 matrix, connect two
SCXI-1378 terminal blocks together with a matrix expansion cable to
double the number of columns.
