Scan rate up to 60 channels/second
Built-in thermocouple reference junction
The Keysight 34901A module for the 34970A/34972A data acquisition/switch unit is a versatile multiplexer for general scanning. It combines a high-density, multi-function switch with up to 60 channels per second of scan rate for a wide range of data acquisition applications.
2-wire and 4-wire channels can be mixed on the same module. Two additional inputs with fuses (22 channels total) deliver up to 1A of current to the internal DMM for AC and DC current measurements without the use of external shunt resistors.
