The DAQ3120 benchtop data acquisition system combines a 6½-digit DMM with a modular design for versatile measurement and analysis. The 3-slot mainframe and built-in DMM offer flexibility and high-resolution (0.0035% basic DCV accuracy). It measures 14 signal types including; temperature, voltage, current, resistance, frequency, capacitance, and strain. Five switch modules customize functionality, with the DM309 extending voltage range and the DM300 enabling scan rates up to 450 channels/s. The system captures high-speed data (38.4 kSa/s sample rate), stores 100 kpts internally, and logs data via USB. Connectivity includes LAN, USB, and optional micro GPIB. Included DAQ-Data logger software simplifies test configuration and control.
