The Agilent 34970A gives you the resolution, accuracy, repeatability, and speed you ve come to expect from an Agilent data acquisition system. It provides the measurement muscle you need, along with signal routing and control capability, in a flexible, modular format that can grow and change to match your varied applications.
Powerful measurements
The internal 6 1 /2-digit DMM brings the power and performance of a world-class stand-alone DMM to the Agilent 34970A, but at a fraction of the cost and in a fraction of the space. It is as accurate as the best bench DMM available: 0.004% basic 1-year dcV accuracy, 0.06% basic 1-year acV accuracy, and 0.01% basic 1-year resistance accuracy. Our patented Multi-slope III A-D technology offers incredible linearity (2 ppm of reading +1 ppm of range) along with 22 bits of real resolution. And since it is an integrating A/D, it provides excellent noise rejection as well, which is a nice change from noisy PC plug-ins and sampling A/Ds. No more averaging lots of samples just to see the real data you wanted. And if you need high scan rates, the Agilent 34970A is capable of delivering fully converted measurements directly to HP-IB or RS-232 at speeds of up to 250 ch/s, even with alarms, scaling, statistics and memory/timestamp enabled. The input section of the DMM is optically isolated and shielded from the Agilent 34970A's earth-referenced circuitry and computer interface, offering up to 300 V of input isolation. This is important for reducing ground loop and common mode voltage errors associated with long wiring runs and floating measurement sources.
Flexible functionality
The DMM is installed inside the chassis rather than in one of the slots, leaving all three mainframe slots free for switch and control modules. You can choose from eight different modules to get the precise functionality you need now, while giving you flexibility for future expansion. The internal DMM gives you the flexibility to measure 11 types of inputs easily and inexpensively. The built-in signal conditioning and conversion routines turn raw inputs directly into real information. Each measurement channel is independently configurable, so you can set different measurement functions, scale factors and alarm limits, even on adjacent channels. Advanced measurement features such as offset compensation, variable integration time and delay are also selectable on a per-channel basis.
Get better measurements with built-in signal conditioning
The Agilent 34970A architecture offers advantages over other data acquisition solutions which rely on external or plug-in signal conditioning modules for handling functions other than dcV:
Software drivers
Your months of test system software development time need not go to waste.
Software drivers that support HP VEE and ¹National Instruments® LabView® are
available at:
