The National Instruments NI-5791 is a highly advanced RF Adapter Module designed for seamless integration with compatible NI FlexRIO™ FPGA modules, specifically the PXIe-796xR series. This module leverages cutting-edge CLIP technology, offering exceptional performance in radio frequency applications. It features a dual-channel ADC capable of sampling at 130 MS/s with 14-bit resolution, along with a digital-to-analog converter (DAC) to facilitate comprehensive RF signal processing. To accommodate complex multi-channel systems, the NI-5791 includes dedicated local oscillator (LO) input and output connectors for efficient LO sharing.

This RF adapter module incorporates various clocking options and programmable attenuators, as well as selectable receiving and transmitting filters to enhance signal integrity. Its front panel is equipped with multiple connectors, including RX IN, AUX I/O, CLK IN, LO OUT, LO IN, CLK OUT, and TX OUT, allowing for easy connectivity using standard 50 Ω SMA cables. The module supports RF signal processing across a frequency range of 0.2 GHz to 4.4 GHz and requires the National Instruments SHH19-H19-AUX cable (Part Numbers: 152629-01 or 152629-02) to access programmable function interface (PFI) and digital I/O (DIO) signals via the AUX I/O connector.

For High-Level Description Language (HDL) integration, the NI-5791 provides a component-level intellectual property (CLIP) core, enabling users to access in-phase (I) and quadrature (Q) data for one receiving and one transmitting channel. Additionally, the CLIP facilitates routine configuration of the module's programmable attenuators, baseband clocking, receive amplifier, and LO filters, making it an ideal choice for sophisticated RF applications. With dimensions of 5.1 x 0.8 x 4.7 inches and a weight of 14.6 oz, this module is built to enhance the capabilities of RF systems while maintaining a compact form factor. A 2-3 year warranty is provided, and user and maintenance manuals are readily available for download. For pricing information, please contact a sales representative.
