B&K Precision DAQ3120-GPIB Benchtop Data Acquisition System

Overview

The B&K Precision DAQ3120-GPIB is a benchtop data acquisition and logging system that combines a high-precision 6½-digit digital multimeter with a modular measurement platform. This variant includes a built-in micro GPIB interface for seamless integration with laboratory automation systems. The system features a large 4.3-inch TFT color display and intuitive user interface, making it easy to acquire, analyze, and log various physical measurements. With 0.0035% basic DCV accuracy and support for up to 120 channels, the DAQ3120-GPIB delivers high-resolution measurement capability for diverse applications.

The system provides signal conditioning and analog-to-digital conversion for 14 different input types, including temperature measurements using thermocouples, RTDs, and thermistors, plus DC/AC voltage and current, resistance, frequency, period, capacitance, and strain. With a reading speed of 38,400 readings/s, the DAQ3120-GPIB can capture high-speed phenomena and store up to 100 kpts of data in non-volatile internal memory with time stamps for all readings.
