National Instruments NI-5731 Digitizer Adapter Module for FlexRIO

The NI‑5731 (Part number: 781657-02) is a Digitizer Adapter Module for FlexRIO designed by National Instruments. This module becomes a high-speed digitizer when joined with a PXI FPGA Module for FlexRIO. The NI 5731 can concurrently sample two channels. These channels can operate at 40 MS/s. Individuals experience high-performance with the NI–5731 since it can perform actual processing and streaming of analog data. This is done with enhanced Analog to Digital Converters. The NI‑5731 also contains bypass hardware filters, a Bessel, and selectable elliptic. This Digitizer Adapter Module for FlexRIO is perfect for applications which involve high data streaming rates and is suitable for deployed high-performance solutions, as well as in-line data processing.

The NI-5731 module offers flexible measurement competencies and the assistance of hardware customization through a user-programmable FPGA. The NI-5731 can provide a higher dynamic range at 12 bits of resolution. This is much better than an 8-bit oscilloscope. It also provides sufficient bandwidth to get a multiple of common signals on two simultaneously sampled channels. The NI-5731 has a 2 Vpp input range and 50 Ω input impedance. This module is structured with 0 dB, 6 dB, or 12 dB programmable gain. All these characteristics enable the NI 5731 to provide the maximum dynamic range for low-amplitude signals.

This Digitizer Adapter Module for FlexRIO comes with external reduction, which enables the module to securely gain larger voltages. A selectable Bessel filter decreases the group delay over the input bandwidth and is used for time-domain applications. The NI-5731 also has an elliptic filter, which increases flat bandwidth and is used for frequency-domain applications. The NI-5731 has a filter bypass path, which enables under sampling or external user-customizable input filtering and is utilized for maximum flexibility.
