Overview
The National Instruments PXI-2530 and SCXI-1130 are high-density,
multiconfiguration multiplexer/matrix switches. With 14 possible
configurations and multiple expansion options, these modules offer
an excellent solution for large or complex-channel-count systems.
The NI PXI-2530 and NI SCXI-1130 incorporate reed relays into the
PXI and SCXI platforms for long-life functionality. At up to 10 times
the speed of traditional armature relays, the PXI-2530 and SCXI-1130
are an ideal front-end for high-speed measurement devices, such as the
NI PXI-4070 6¹â„2-digit FlexDMM.
Modes of Operation
The PXI-2530 and SCXI-1130 are completely software configurable
to operate as a multiplexer, matrix, or independent switch bank.
For matrix and multiplexer hardware options, see Table 1.

Multiplexer
You can configure the PXI-2530 and SCXI-1130 in several different
multiplexer configurations. The 1 and 2-wire modes are designed for
measuring/sourcing voltage or 2-wire resistance measurements.
For improved accuracy of resistance measurements, configure the
PXI-2530 and SCXI-1130 in 4-wire mode.
Matrix
Configured as a matrix, the PXI-2530 or SCXI-1130 becomes a
general-purpose signal router. With the TB-2631, the PXI-2530
forms a 4x32 matrix in 1-wire mode and a 4x16 matrix in 2-wire
mode. The TB-2632 is also available to configure the PXI-2530 into
an 8x16 1-wire matrix. Using the SCXI-1378 terminal block, the
SCXI-1130 can form a 4x64 1-wire or a 4x32 2-wire configuration
matrix. With the SCXI-1379, an 8x32 1-wire matrix is available.
Through software, you can control the matrix to connect any row(s)
to any column(s).
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.
