NI-5733

The NI-5733 is a Digitizer Adapter Module for FlexRIO from National Instruments, designed for high-speed analog signal acquisition, real-time data processing, and FPGA-based measurement systems. When combined with a compatible PXI FPGA Module or Controller for FlexRIO, the NI-5733 creates a high-speed digitizer that can simultaneously sample two analog input channels at 120 MS/s. This module features 2 analog input channels, 16-bit resolution, and high-performance A/D converters, making it suitable for applications that require accurate waveform capture, high data streaming rates, and in-line signal processing.

The NI-5733 Digitizer Adapter Module is built for users who need more flexibility than a fixed-function digitizer. By working with FlexRIO FPGA hardware, the NI-5733 allows engineers to implement custom signal processing, triggering, filtering, data reduction, and streaming functions directly in hardware. This FPGA-based architecture makes the module useful for advanced test systems where real-time performance, customized algorithms, and high-speed data handling are important.

One of the key features of the National Instruments NI-5733 is its selectable hardware filtering. The module includes selectable elliptic, Bessel, and bypass hardware filters. The elliptic filter is useful for frequency-domain applications where flat bandwidth is important, while the Bessel filter is suitable for time-domain applications where reduced group delay is needed. The bypass filter path gives users more flexibility for applications such as undersampling or custom signal conditioning.

The NI-5733 FlexRIO Adapter Module supports simultaneous two-channel acquisition at 120 MS/s, making it suitable for applications that require synchronized signal capture. It can be used for waveform digitization, communications testing, radar and sonar research, ultrasound acquisition, transient signal analysis, and automated validation systems. Because the module works with high-performance A/D converters and FPGA processing hardware, it is especially useful for systems that require in-line processing and high-throughput data streaming.

In system integration, the NI-5733 must be paired with a compatible FlexRIO FPGA module or FlexRIO controller. This combination allows users to create a customized PXI-based digitizer system rather than using a standard standalone instrument. Engineers can use the FPGA to process acquired analog data in real time, reduce the amount of data transferred to the host computer, and improve overall system efficiency in demanding measurement environments.

The National Instruments NI-5733 is suitable for laboratory research, automated test platforms, high-speed measurement systems, embedded signal processing, and deployed high-performance test solutions. It is a practical choice for applications that require a balance of sampling speed, resolution, FPGA flexibility, and analog signal acquisition capability.

Overall, the NI-5733 Digitizer Adapter Module for FlexRIO is a flexible high-speed digitizer adapter for users who need 2-channel analog input, 16-bit resolution, 120 MS/s simultaneous sampling, selectable hardware filters, and FPGA-based real-time processing. With its FlexRIO architecture, the NI-5733 is well suited for advanced data acquisition, signal analysis, waveform digitization, and custom PXI measurement systems.
