Agilent/Keysight 10466A

The Agilent/Keysight 10466A is a C-size VXI switching module that implements a 4×64 two-wire matrix for precision signal routing in test systems. It switches both high and low sides at each crosspoint using latching armature relays, delivering cost-effective matrix expansion within complex measurement setups. The module shares its switch card architecture with the E1465A and E1467A, with terminal block configuration determining the specific matrix topology.

Rows and columns can be daisy-chained across multiple modules to build larger matrices - a fully populated E1401B 13-slot mainframe supports up to 3072 two-wire crosspoints. Four interconnected 10466A modules create a 4×256 matrix using standard expansion cables.

Compatibility & Integration The 10466A integrates into VXI mainframes and shares switch card architecture with the E1465A and E1467A modules. Expansion requires daisy-chain cables (e.g., E1466-80002). The E1467A with expansion terminal block options (201/211) and Z2220A series cables offers an alternative 8×32 matrix configuration with faster access and simplified cable management.
