3-slot mainframe with built-in GPIB and RS232 interfaces

8 switch and control plug-in modules to choose from

Built-in signal conditioning measures thermocouples, RTDs and thermistors, AC/DC volts and current; resistance; frequency and period

50k readings of non-volatile memory holds data when power is removed

Hi/LO alarm limits on each channel, plus 4 TTL alarm outputs

BenchVue software enabled: BenchVue DAQ Control and Analysis app enables you to create tests without programming

 The 34970A data acquisition / data logger switch consists of a three-slot mainframe with a built-in 6 1/2 digit digital multimeter. 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.

40 Channel Single-Ended Multiplexer

Single-wire switching for common-low applications

60 ch/s scanning

Built-in thermocouple reference junction

 Use the 34908A module for the 34970A/34972A Data Acquisition/Switch Unit for the greatest density in common-low applications, such as battery test, component characterization, and benchtop testing. Each module switches 40 one-wire inputs. All two-wire internal measurements except current are supported. The module low connection is isolated from earth and can float up to 300 V.
