34908A CAL D

The 34908A CAL D from Keysight Technologies is a 40 channel single ended multiplexer module for 34970A/34972A data acquisition/switch units. This 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 300V. DMM connections are accessible only through the 34908A low frequency multiplexer. The 34908A does not allow multiple channel closures at any time.
