Keysight USB Modular Data Acquisition Modules
The USB data acquisition (DAQ) family gives you the choice and flexibility to create solutions that evolve and expand
according to your changing measurement needs. You can quickly and easily acquire, measure, and analyze data from
electrical, mechanical, physical, and acoustical phenomena.
The DAQ series includes multifunction measurement modules, simultaneous-sampling measurement modules, two types
of digital input/output (DIO) devices, and a thermocouple input.
