Agilent/Keysight 34934T

The Keysight 34934T is a terminal block accessory for discrete wiring integration with the 34934A Quad 4x32 Reed Matrix module in the 34980A Multifunction Switch/Measure Unit mainframe. It has 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 4x128 1-wire to 16x32 1-wire arrangements - with expansion headers for scaling to larger systems.

Technical Specifications

• Wire Gauge Support: Up to 20 AWG (typical); up to 24 AWG when all 144 lines are utilized


• Voltage Rating: Compatible with matrices rated to ±100 Vpk


• Connector Type: Screw terminals for discrete field wiring


• Expansion: Headers provided for interconnecting multiple terminal blocks

Key Features

• Configuration flexibility across multiple matrix sizes - 34934T-001: 4x128 1-wire, 4x64 2-wire, or dual/quad 4x32 matrix modes - 34934T-002: 8x64 1-wire, 8x32 2-wire, or 16x32 1-wire modes


• Discrete wiring interface eliminates reliance on pre-fabricated harnesses


• Modular design supports expansion for larger switching matrices


• Supports field wiring up to 20 AWG in fully loaded configurations

Typical Applications

• Automated test equipment (ATE) systems with multi-point signal routing


• Data logging and acquisition setups requiring channel multiplexing


• Complex switching matrices for precision measurement and validation


• High-density test point scanning across distributed measurement locations

Compatibility & Integration Designed exclusively for the Keysight 34980A mainframe and 34934A Quad 4x32 Reed Matrix module. Integrates within the 34980A's eight-slot architecture, allowing engineers to combine multiple switching and measurement modules in a single instrument. Expansion headers enable creation of larger matrices through terminal block interconnection.
