The NI-5751B Digitizer Adapter Module for FlexRIO by National Instruments signifies a significant enhancement over its predecessor, offering improved performance and efficiency tailored for sophisticated data acquisition systems. This module, with the manufacturer’s part number 784061-01, is designed to operate seamlessly with PXI FPGA Modules, leveraging the capabilities of the Kintex-7 FPGA for high-speed digitization and real-time processing applications. The NI-5751B features 16 single-ended, DC-coupled analog input channels, supporting a voltage input range of -1 V to 1 V, with a maximum sampling rate of 50 MS/s and a resolution of 14 bits.

The module includes three clock sources, providing flexibility with frequencies ranging between 30 MHz and 50 MHz through an onboard 50 MHz clock, Sync Clock, or CLKIN via an SMB connector. Users can benefit from its digital I/O capabilities, featuring 16 VHDCI terminals—eight inputs and eight outputs—with a maximum output toggle frequency of 1 MHz and a pulse width of 10 ns. Ideal for applications in online data processing, time and frequency-domain analysis, and medical experimentation, the NI-5751B combines high-speed analog I/O with versatile digital interfacing, making it an essential tool for advanced measurement and control systems. For detailed documentation, both the user and maintenance manuals are available for download, and pricing can be obtained by contacting a sales representative.
