Description

Detailed Parameter Table

Product Introduction

The DAQ973A from Keysight Technologies is a high-performance, modular data acquisition system designed to deliver precision measurements, broad channel scalability and flexible connectivity in one compact mainframe. With a built-in 6½-digit Digital Multimeter (DMM) offering 22-bit resolution and a basic accuracy of 0.003% for DC voltage, the DAQ973A supports a wide range of signal types — from temperature sensors and resistance measurements to AC/DC voltage and current, frequency, capacitance and more.

Housed in a 3-slot mainframe, the DAQ973A allows users to select and install plug-in modules tailored to their specific application needs, whether that is high-channel multiplexing, matrix switching, actuator control or high-speed digitizing. With embedded USB, LAN (LXI) and GPIB interfaces, it integrates effortlessly into laboratory, production test or process monitoring systems, enabling automated test sequences, remote access and data logging.

When deployed, the DAQ973A serves as the central hub of a versatile measurement setup — ensuring reliable data capture, signal conditioning, alarm monitoring and logging for R&D, manufacturing test, environmental monitoring or system diagnostics. Its combination of modular flexibility, measurement quality and connectivity makes it a strategic choice for engineers seeking to expand or upgrade their acquisition infrastructure.

Core Advantages and Technical Highlights

High-resolution DMM performance:
The DAQ973A’s built-in 6½-digit DMM offers exceptional resolution and accuracy. With 22-bit conversion and a basic DC voltage accuracy down to 0.003%, it empowers users to trust the fidelity of their measurements and reduce uncertainty in critical test applications.

Flexible modular architecture:
The 3-slot mainframe design supports a family of plug-in modules, enabling the DAQ973A to be configured for multiplexing hundreds of channels, matrix switching, simultaneous sampling, RF switching or digital/analog I/O. This modularity ensures the system can grow or adapt as requirements change.

High channel throughput:
With scanning rates up to 450 channels per second and support for up to 120 channels per system, the DAQ973A allows rapid acquisition of large-scale signal arrays — ideal for temperature profiling, environmental chamber monitoring, or component screening where speed matters.

Comprehensive signal conditioning:
The system accepts a wide variety of input signal types directly: thermocouples, RTDs, thermistors, DC/AC volts and current, 2- and 4-wire resistance, frequency/period, capacitance and diode tests. This eliminates the need for multiple dedicated instruments and simplifies infrastructure.

Built-in connectivity and data handling:
With USB, LAN and GPIB interfaces, the DAQ973A connects seamlessly to PC software, enabling measurement setup, visualization, automation and logging. Its non-volatile memory and USB flash drive support add greater flexibility for standalone logging deployments or remote operation.

Scalable and future-ready:
Because users can mix plug-in modules based on current needs and expand later, the DAQ973A ensures investment protection. Its compatibility with earlier systems and wide module ecosystem makes it a practical choice for long-term infrastructure.

Typical Application Scenarios

The DAQ973A is ideally suited for a diverse range of measurement and monitoring tasks across industries. Some typical use-cases include:

• Environmental chamber and temperature profiling: capturing large numbers of thermocouple/RTD channels with alarm monitoring for test labs or component stress testing.
• Automated production test fixtures: coordinating multiple types of sensors and I/O via a modular system to reduce footprint and simplify wiring.
• Process monitoring and logging: integrating into factory or R&D environments to record electrical, thermal and mechanical signals with networked connectivity.
• Research and development characterization: measuring AC/DC voltages, currents, resistance, capacitance and frequency in high-accuracy experiments or validation setups.
• Retrofits of existing data acquisition setups: replacing older systems with the DAQ973A mainframe while leveraging existing plug-in modules and extending capabilities.

In each scenario, the DAQ973A brings value through its combination of measurement integrity, channel flexibility and networked data management — enabling better insight, higher throughput and greater reliability.
