CAN - en Keysight 34970A/34972A Data Acquisition Modules Selection Guide
Keysight offers several different modules for the 34970A / 34972A data acquisition units. The key benefit of the Keysight platform is the availability of multifunction and multiplexer modules. Multifunction modules can take several different inputs, including thermocouple signal. Multiplexer modules are capable of combining inputs from different slots into and recognizing it as one signal. An example would be an RTD signal measurement, which needs to combine four resistance inputs into one overall measurement. Keysight also offers RF modules with SMB inputs to 2 GHz and BNC-SMB adapters to 1 GHz. Keysight also allows cascading of multiple banks of data acquisition units into large data logging systems.
