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. 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.
