The Keysight DAQ970A/DAQ973A is a data acquisition system built around a compact 3-slot mainframe with a built-in 6½-digit (22-bit) internal DMM. The measurement engine from a high-performance benchtop DMM is embedded inside the mainframe, combining proven measurement performance, universal inputs with built-in signal conditioning, and modular flexibility in a single low-cost package. It delivers 0.003% basic DC voltage accuracy, ultra-low reading noise, and scan rates of up to 450 channels per second, giving an engineer both the speed and the accuracy needed for demanding acquisition work.

Configured with a 20-channel relay multiplexer, the system becomes a powerful, low-cost data logger for characterization applications, and it also serves as a data acquisition front end for automated test. Typical data-logging and monitoring uses include environmental chamber monitoring, component inspection, benchtop testing, process troubleshooting, and temperature profiling. It supports both the R&D engineer characterizing a new design and the manufacturing engineer building a test system or troubleshooting a process. The 40-channel single-ended multiplexer adds density for applications such as battery test and component characterization.

Brand Heritage

Keysight Technologies traces its roots to the test and measurement business of Hewlett-Packard. That business was spun out as Agilent Technologies in 1999, and in 2014 Agilent's electronic measurement division became the independent company Keysight Technologies. Equipment from across that history is frequently encountered under all three names.

Compare Other Models in This Series

The DAQ970A/DAQ973A family pairs a common 6½-digit (22-bit) measurement engine with a 3-slot modular mainframe, giving the simple operation and low per-channel cost of a data logger alongside the flexibility and performance of a modular data acquisition system. Both mainframes share the same internal DMM, the same 4.3-inch color display, and the same compatibility with all nine plug-in switch, RF, and control modules.

The two models differ in their standard remote-control interfaces. The DAQ970A provides built-in Gigabit LAN and USB 2.0, while the DAQ973A carries the same LAN and USB connectivity plus a built-in GPIB interface for ATE environments that depend on IEEE-488 control.

Each model in the DAQ970A/DAQ973A family below links to its own dedicated product page, where new pricing and availability are matched to that exact configuration. Choose the mainframe and module combination that fits your channel count and connectivity requirements.

The defining difference across the family is connectivity: the DAQ970A ships with built-in LAN and USB, and the DAQ973A adds a built-in GPIB interface to that same LAN and USB set. Both mainframes accept up to three of the nine available plug-in modules in any combination and deliver identical measurement performance, channel density, and 1-million-reading memory.

Beyond connectivity, configuration differences come from module choice rather than the mainframe—multiplexer type, scan speed, voltage and current ratings, and switching topology all vary by module. The comparison table below summarizes the interface and configuration differences across the family.

Model	Type	Channels	Max Voltage
DAQ970A	DAQ Mainframe (USB, LAN)	Up to 120	300 V
DAQ973A	DAQ Mainframe (USB, LAN, GPIB)	Up to 120	300 V
DAQM900A	2-wire solid state (4-wire selectable)	20	120 V
DAQM901A	2-wire armature (4-wire selectable)	20 + 2	300 V

Important: The internal DMM input section is optically isolated and shielded from the earth-referenced circuitry and computer interface, providing up to 300 V of input isolation.

Important: The DAQ970A/DAQ973A mainframe requires at least one low-frequency multiplexer module to make measurements: only the DAQM900A, DAQM901A, DAQM902A, and DAQM908A modules connect to the internal DMM. Modules are ordered separately ('buy only what you need—and add more modules later as your application grows').

Important: Up to three modules, in any combination, can be inserted into a single mainframe.

Important: The DAQM905A RF Multiplexer uses SMB connectors; a standard set of (10) BNC-to-SMB adapter cables is provided with each RF module for BNC connections (2 GHz bandwidth via SMB, 1 GHz via the BNC-to-SMB adapters).

Important: On-module screw terminals accept wire sizes from 16-gage to 22-gage; twenty-gage wire is recommended for high channel count applications.

Important: The DAQM902A requires user-provided shunt resistors for current measurements.

Important: All VAC ranges are limited to 8 x 10^7 Volt-Hz.

Important: Bridge strain measurements require an external power supply and bridge completion (not supplied).

Recommended pairing: listed accessories include the 34307A J-type thermocouples and 34308A 10 kΩ thermistors for temperature measurements and the 11062A Kelvin clip set for resistance measurements.

Recommended pairing: add the DAQM909A 4-channel 24-bit simultaneous-sampling digitizer to unlock BenchVue DAQ frequency-domain (FFT, THD, THD+N, SINAD) and time-domain measurements within the same mainframe.
