NI-5771

The NI-5771 is a Digitizer Adapter Module for FlexRIO from National Instruments, designed for high-speed analog data acquisition, real-time signal processing, and FPGA-based PXI measurement systems. When combined with a compatible PXI FPGA Module or Controller for FlexRIO, the NI-5771 creates a high-speed digitizer for applications that require fast sampling, high analog bandwidth, and in-line data processing. This module features 2 analog input channels, 8-bit resolution, 900 MHz analog bandwidth, and sampling rates up to 3 GS/s.

The NI-5771 Digitizer Adapter Module can simultaneously sample two channels at 1.5 GS/s or sample one channel at 3 GS/s. This makes it suitable for both dual-channel synchronized acquisition and maximum-speed single-channel waveform capture. With its high-performance A/D converters, the NI-5771 can stream and process analog data in real time, making it useful for systems that require high data throughput and fast signal analysis.

The National Instruments NI-5771 is part of the FlexRIO platform, which allows users to combine adapter modules with FPGA hardware. This architecture gives engineers the ability to implement custom signal processing, filtering, triggering, data reduction, and streaming functions directly in FPGA logic. Compared with a fixed-function digitizer, the FlexRIO design provides more flexibility for advanced test systems, research platforms, and deployed high-performance measurement solutions.

The NI-5771 FlexRIO Adapter Module is suitable for applications such as RF signal acquisition, communications testing, radar signal analysis, transient signal capture, high-speed waveform digitization, and automated validation systems. Its 900 MHz bandwidth and GS/s-level sampling performance make it useful for capturing fast-changing analog signals where standard DAQ modules do not provide enough speed or bandwidth.

In system integration, the NI-5771 must be paired with a compatible FlexRIO FPGA module or FlexRIO controller. This combination allows users to build a customized PXI-based digitizer system and process acquired analog data directly in hardware before sending results to the host computer. This helps reduce data transfer load and improves real-time system performance in demanding measurement environments.

The NI-5771 Digitizer Adapter Module for FlexRIO is ideal for applications that require in-line data processing, high data streaming rates, and deployed high-performance solutions. It is commonly used in advanced laboratory systems, RF and wireless test systems, physics experiments, high-speed electronics testing, and custom FPGA-based measurement platforms.

Overall, the National Instruments NI-5771 Digitizer Adapter Module for FlexRIO is a powerful high-speed digitizer adapter for users who need fast analog signal acquisition, FPGA-based processing, and high-bandwidth data streaming. With 2 channels, 8-bit resolution, 900 MHz analog bandwidth, and sampling rates up to 3 GS/s, the NI-5771 is well suited for high-speed measurement, RF acquisition, waveform digitization, and custom PXI test applications.
