Agilent/Keysight 34923T

The Agilent/Keysight 34923T is a detachable terminal block accessory that interfaces with the Keysight 34923A 40/80-channel reed multiplexer module. It enables discrete wiring connections from external test setups to the multiplexer, supporting signal routing and data acquisition in automated test environments. Two configuration options accommodate 1-wire and 2-wire measurement topologies.

Screw-type terminals accept wire gauges up to 20 AWG for fewer than 100 connections, or 24 AWG for 100 or more connections, ensuring reliable signal integrity across diverse switching applications.

Technical Specifications

• Configuration Options: 34923T-001 (2-wire) and 34923T-002 (1-wire)


• Wire Gauge: Up to 20 AWG (< 100 connections) or 24 AWG (≥ 100 connections)


• Connection Type: Screw-type terminals


• Physical Form: Detachable terminal block


• Safety Interlock: When used with Keysight 34980A mainframe, the 34923T-001 automatically shorts interlock pins 17 and 33 on Bank 2, enabling Bank 2 Analog Bus relays and preventing inadvertent high-voltage routing to the D-sub connector

Key Features

• Direct screw-terminal interface for external signal connections


• Supports both single-wire and two-wire measurement configurations


• Automatic interlock shorting in 34923T-001 variant eliminates manual configuration


• Compatible with standard lab wire gauges for field deployment
