Agilent DAQM900A 20 Channel Solid-state Multiplexer Module

The Agilent DAQM900A is a 20-channel solid-state multiplexer module designed for integration into automated measurement systems. It routes multiple input signals to a single measurement instrument, enabling efficient high-throughput data acquisition. Built on solid-state relay technology, the module delivers fast switching speeds and extended operational life compared to mechanical alternatives, making it suitable for research and development, industrial monitoring, and comprehensive system testing.

Technical Specifications

• Channels: 20 single-ended input channels


• Switching Technology: Solid-state relays for fast switching and long operational life


• Signal Integrity: Low signal degradation; minimized insertion loss, crosstalk, and OFF-isolation for accurate small-signal measurements


• Contact Resistance: Low contact resistance minimizes voltage drop across the switch


• Switching Speed: Fast switching capable; enables high-throughput testing and measurement

Key Features

• Single-ended channel architecture optimized for signal routing in automated test environments


• Solid-state design eliminates mechanical wear and enables rapid channel switching


• Low-loss signal path preserves measurement accuracy across all 20 channels


• Mainframe-based integration eliminates standalone hardware requirements

Typical Applications

• Multi-channel data acquisition in automated test systems


• Signal routing and switching in industrial monitoring


• Research and development measurement systems


• High-speed switching applications requiring minimal signal degradation

Compatibility & Integration The DAQM900A works with the Agilent 34980A Multifunction Switch/Measure Mainframe. The module installs directly into the mainframe chassis and is controlled via SCPI commands and programming interfaces supporting LabVIEW, C++, and Python through manufacturer-provided drivers and libraries.
