The Agilent 34970A Data Acquisition/Switch mainframe claims to provide a high performance standalone data acquisition system at a fraction of the cost of other systems, even in systems costing three to five times as much. This is made possible by adapting technology from other top-of-the-line Agilent DAQ products, and then putting that technology into a simplified, smaller, high-quality electronics package that incorporates custom ICs to reduce parts count and cost.

Agilent 34970A Data Acquisition/Switch mainframe is like having an independent, high-performance DMM behind each channel, where each DMM is capable of measuring temperature, ac/dc volts, resistance, frequency, or current. The 34970A internal autoranging DMM functions directly to measure 11 different functions, eliminating the need for expensive external signal conditioning.

The 34970A features 22 bits of resolution (6.5 digits of accuracy), which evaluates to 0.004 percent basic dcV accuracy, and ultra-low reading noise.



One of the best features is that the 34970A provides free software to save time and money, that helps avoid spending valuable time writing or configuring software. Agilent BenchLink Data Logger II software provides a familiar Microsoft Windows® interface for test configuration
and real-time data display and analysis. The data logging application is included with every standard Agilent 34970A.

Multiplexer Modules allow selection between the broad functionality of the 34901A, the high speed scanning of the 34902A, or the single-ended density of the 34908A. These three modules are the only way to connect to the 34970A internal DMM. They can be used to scan with external instruments as well. All multiplexer modules employ break-beforemake scanning, ensuring only one closed channel (or channel pair) at a time. To obtain multiple channel closures, choose the 34901A and 34902A modules when not configured for scanning. The 34908A does not allow multiple channel closures at any time.
