Keysight / Agilent 34923A 40/80 Channel Reed Multiplexer

The Agilent 34923A module for the 34980A Multifunction Switch/Measure Unit is a high speed-multiplexer for general purpose scanning. It uses reed relays to achieve scan rates up to 500 channels-per-second. Use this module for high-throughput automated test applications as well as high-speed data logging and monitoring tasks.

Current measurements can be accomplished with user supplied shunts. Standard 50-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions. 2- and 4-wire channels may be mixed on the same module, or configure as an 80 1-wire multiplexer.

The 34923T is a terminal block for the 34923A 40/80-channel reed multiplexer. This terminal block is used for discrete wiring. It supports up to 20 AWG wire size typical for &lt:100 connections or 24 AWG for >100 connections. The following two terminal blocks are available to facilitate wiring connections to the 34923A module:

  • 34923T-001 (Option 001) Terminal Block for 2-wire configurations
  • 34923T-002 (Option 002) Terminal Block for 1-wire configurations

The 34923T is a detachable terminal block with screw-type connections that provides a flexible method for connecting external wiring.
