Description
T34970A, 3-slot mainframe with built-in 6.5 digit multimeter provides flexibility with a choice
of 8 switch & control, plug-in modules. Built-in GPIB and RS-232 interfaces make connection easy.
The Agilent 34970A consists of a three-slot mainframe with a built-in 6 ½ digit DMM. Each channel
can be configured independently to measure one of 11 different functions without the added cost or
hassles of signal-conditioning accessories. Choose from eight optional plug-in modules to create a
compact data logger, full-featured data acquisition system or low-cost switching unit. On-module
screw-terminal connections eliminate the need for terminal blocks and a unique relay maintenance
feature counts every closure on every switch for easy, predictable relay maintenance. Our most
popular module 34901A features a built-in thermocouple reference and 20 two-wire channels.
Agilent BenchLink Data Logger software is included with the 34970A. BenchLink Data
Logger gives you a familiar Microsoft Windows interface for test configuration and real-time
data display and analysis. Setup and make measurements quickly, export data or use the
built-in graphs to log your results.
