3.1 PXI-7921 Topology
The ADLINK PXI-7921 is the armature relay multiplexer module which
consists of a 24×1 2-wire multiplexer. It also can operate as two groups of
12x1 2-wire multiplexer, four groups of 6×1 2-wire multiplexer, one group of
48×1 1-wire multiplexer, or one group of 12×1 4-wire multiplexer. These
configurations are totally software programmable.
The PXI-7921 typically connects one instrument, such as a DMM or digitizer,
to many measurement points or a signal source to several points needing
excitation. Without jumper settings, complete software programming makes
PXI-7921 easy-to-use and dedicated for versatile applications. PXI-7921
fully supports PXI trigger functions. Multiple switch modules can therefore be
synchronized or triggered without additional field-wiring.
