The BK Precision DAQ3120 Benchtop Data Acquisition System combines a 6-1/2 digit digital multimeter (DMM) and a data logger together in a compact and modular design. This instrument offers a complete solution for acquiring, analyzing, and logging various physical measurements. The large, 4.3 in. TFT color display and intuitive user interface simplify operation, while the 3-slot mainframe combined with the DMM functionality ensures both flexibility and high-resolution measurement capability.

The system delivers high accuracy with a basic DCV accuracy of 0.0035%. Signal conditioning and analog-to-digital conversion of 14 different input types, including temperature (via thermocouples, RTDs, and thermistors, all sold separately), AC/DC voltage and current, resistance, frequency, period, capacitance, and strain, are all provided. The wide range of measurement capabilities allows the DAQ3120 to address diverse applications.

The DAQ3120 provides versatile connectivity interface options including LAN, USB (USBTMC and USBVCP), and digital I/O for seamless integration with the user's PC. For users who wish to utilize micro GPIB interface functionality, the DAQ3120-GPIB model is available for separate purchase. The DAQ-Data Logger PC software offers an intuitive solution for test configuration and control which allows for a streamlined data acquisition workflow.

The DAQ3120 model provides users with the mainframe only. Five selectable switch modules (all sold separately) enable users to customize the system in order to meet specific application requirements. The DM309 module extends voltage measurement capabilities up to 600VDC or 400VAC while the DM300 module provides scan rates of up to 450 channels per second. The DM301 module features two current channels, the DM303 module offers high density, and the DM304 module provides up to 32 cross-points. With a reading speed of 38400 readings per second, the DAQ3120 can capture high-speed phenomena and store up to 100 kpts of data in the non-volatile internal memory with time-stamps for all readings. Data logging and transfer are facilitated through the USB host port in standalone operation.

Operating Software

DAQ-Data Logger PC Software

The DAQ-Data Logger software provides real-time measurement and display capabilities which allows users to monitor critical parameters as they happen. Users can connect up to four instruments simultaneously and manage multiple data streams effortlessly. The data can be visualized with flexible display options including data tables, trend charts, and histograms.

The tabular formatting of the channels and parameters maximize screen space, making it easy to manage systems with large numbers of inputs. Measurement parameters can be saved and loaded for quick setup and consistent analysis. This software offers a comprehensive solution for efficient and intuitive data acquisition and analysis.

Virtual Front Panel Control via Web Interface

The DAQ3120 features a built-in web interface that enables users to operate the instrument remotely from any device on the network. The web interface provides a virtual front panel that mirrors the DAQ3120 and offers all the same functions such as configuring channels, executing scans, and monitoring measurements.

Due to the interface being built-in, no software is required to be installed. To connect, users can simply type the instrument's IP address or host name into a Java-enabled web browser. For enhanced security and control access, password protection can be enabled. This convenient web interface allows users to easily configure, control, and monitor the instrument remotely.
