Agilent/Keysight 34934C

The Keysight 34934C is a configuration block that expands the switching capability of the 34934A Quad 4x32 Reed Matrix module within the 34980A Multifunction Switch/Measure Unit. It has flexible row and column wiring routing to D-Sub connectors, implement customized matrix topologies for automated test and data acquisition. Two configuration variants support 1-wire and 2-wire switching architectures across multiple matrix sizes.

Technical Specifications

• Switch/Carry Current: 100 V, 0.5 A


• Relay Type: Reed relays with integrated cycle counter for life monitoring


• Row Protection: Integrated protection for reed relay rows


• Module Type: Configuration block for 34934A Quad 4x32 Reed Matrix

Key Features Matrix Configuration Options

• 34934C-001: Enables 4×128 1-wire matrices or 4×64 2-wire matrices


• 34934C-002: Enables 8×64 1-wire matrices, 8×32 2-wire matrices, or 16×32 1-wire matrices Connectivity & Expansion D-Sub connector routing (50-pin and 78-pin variants) simplifies custom wiring of rows and columns. Expansion headers allow daisy-chaining multiple 34934A modules to build larger matrix configurations. Dedicated row expansion cables (Y1135A, Y1136A, Y1137A, Y1138A) support extended topologies.

Typical Applications The 34934C configuration block suits automated test environments requiring reconfigurable switching matrices - signal routing for component characterization, multipoint data acquisition, and complex switching logic in production and R&D test stations.

Compatibility & Integration The 34934C works exclusively with the Keysight 34980A Multifunction Switch/Measure Unit and the 34934A Quad 4x32 Reed Matrix module. It integrates via D-Sub connectors and expansion headers, allowing modular growth within a single chassis architecture.
