44473A 4 x 4 2-Wire Matrix Switch Module
The Agilent 44473A Matrix Switch provides a 4 x 4 matrix of 2-wire
switches. Each node (crosspoint) in the matrix contains a latching relay
that connects a row to a column. Both Hi (H) and Lo (L) lines are
switched. More than one switch can be closed at a time, allowing any
combination of rows and columns to be connected.
Matrix switching provides a convenient way to connect a group of test
instruments to multiple test points on a device or to multiple devices.
This matrix switch offers highly flexible switching for testing devices
over a frequency range of dc to 100 kHz.
Multiple 44473A modules may be connected together to form a larger
matrices. The 44473A can also be used in conjunction with other modules
(such as the 44470A 10-Channel MUX) to provide a wide variety of
switching combinations. When wiring between multiple modules, keep
wire length as short as possible to minimize noise and signal
degradation.
Specifications for the 44473A are given on page 339.
