The Keysight 34934C is a configuration block that expands the switching capability of the 34934A Quad 4×32 Reed Matrix module within the 34980A Multifunction Switch/Measure Unit. It provides flexible row and column wiring routing to D-Sub connectors, enabling users to 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

– 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 4×32 Reed Matrix module. It integrates via D-Sub connectors and expansion headers, allowing modular growth within a single chassis architecture.
