Agilent / Keysight 34934C Configuration block for the 34934A Quad 4×32 Reed Matrix

The Keysight 34934C is a configuration block that expands the matrix switching capabilities of the 34934A Quad 4×32 Reed Matrix module. This accessory enables reconfiguration of row and column wiring through D-Sub connectors, allowing engineers to build larger, more complex matrix topologies beyond the base single-module configuration. Two distinct configuration options support different matrix architectures: the 34934C-001 creates 4×128 1-wire or 4×64 2-wire matrices, while the 34934C-002 creates 8×64 1-wire, 8×32 2-wire, or 16×32 1-wire matrices. Expansion headers facilitate connection of additional modules for scaled signal routing solutions. Designed for integration with the Keysight 34980A Multifunction Switch/Measure Unit mainframe, the 34934C serves system integrators, test laboratories, and applications requiring advanced switching flexibility and high-speed path switching via reed relay technology.
