• 40 Channel Single-Ended Multiplexer
• Single-wire switching for common-low applications
• 60 ch/s scanning
• Built-in thermocouple reference junction

Use the Keysight 34908A module for the 34970A or 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.
