HP/Agilent 34970A Data Acquisition Switch Unit – Used with Option 001

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.
