Specifications and Characteristics (continued)
M9120A 4x32, 2-wire PXI matrix switch
M9120A specifications and characteristics
The M9120A high-density matrix is designed to switch
medium voltage/power signals. The 128, 2-wire armature
relays offer higher voltage switching and up to 60W per
channel. This module is ideal for telecom applications that
need to simultaneously send and return signals.

The matrix module includes a 4-wire-wide bus to route
signals between test instruments and your device under
test. To create larger matrices, multiple modules can be
linked together, for example, four rows of two M9120A
modules can be joined to create a 4x64 matrix. Easily con-
nect to the matrix with a 78-pin Dsub female connector or
cable.
