The Keysight 34934T is a terminal block accessory for discrete wiring integration with the 34934A Quad 4×32 Reed Matrix module in the 34980A Multifunction Switch/Measure Unit mainframe. It provides flexible field wiring connections for automated test systems, data acquisition, and signal routing applications requiring high channel density. The 34934T enables configuration of multiple matrix topologies—from 4×128 1-wire to 16×32 1-wire arrangements—with expansion headers for scaling to larger systems.
