Product Description

Overview

The Keysight DAQM901A module Data Acquisition System is the most versatile 20-channel multiplexer for general-purpose scanning. It combines dense, multi-function switching with 80 channel / second scan rates to address a broad spectrum of data acquisition applications.

On the same module, two-wire and four-wire channels can be combined. The integrated digital multimeter receives up to 1A of current from two extra fused inputs (a total of 22 channels), enabling ac and dc current measurements without the necessity of external shunt resistors.

Frequently Asked Questions (FAQ)

What is the Keysight DAQM901A module designed for?
The Keysight DAQM901A is a versatile 20-channel multiplexer engineered for general-purpose scanning applications. It provides dense, multi-function switching with scanning rates up to 80 channels per second to satisfy wide-ranging data acquisition requirements.
How does the module measure AC and DC current?
The integrated digital multimeter accepts up to 1A of current via two additional fused inputs (providing 22 channels in total), which enables direct AC and DC current measurements without requiring external shunt resistors.
What signal types can be evaluated and transformed by this system?
The system evaluates and transforms 14 distinct input signals, including temperature (via thermocouples, RTDs, and thermistors), DC and AC voltage, 2-wire and 4-wire resistance, frequency and period, DC and AC current, capacitance, as well as direct strain and bridge strain.
What are the maximum scan rates and channel capacities supported?
The platform can achieve scan rates of up to 450 channels per second, accommodates up to 120 channels per system across its 3-slot mainframes, and features an integrated scanning memory capacity capable of holding up to one million points.
Is the system backwards-compatible with legacy data acquisition units?
Yes, it provides code compatibility with the legacy Keysight / Agilent 34970A and 34972A systems, allowing for straightforward migration and integration into existing test environments.
What connectivity options are available for data logging and setup?
The mainframe comes standard with LAN and USB interfaces for PC connection (with GPIB included on the DAQ973A model), USB flash drive logging support for standalone operations, and BenchVue DAQ software with advanced time and frequency domain measurement tools.
