The NI 5791 can upconvert and downconvert RF signals ranging from 200 MHz to 4.4 GHz.

This document contains signal information and lists the specifications of the NI 5791R, which

is composed of the NI FlexRIO FPGA module and the NI 5791. This document also contains

tutorial sections that demonstrate how to acquire data using a LabVIEW FPGA Example VI

and how to create and run your own LabVIEW project with the NI 5791R.

Note NI 5791R refers to the combination of your NI 5791 adapter module and

your NI FlexRIO FPGA module. NI 5791 refers to your NI 5791 adapter module

only.

Note The NI 5791 is only compatible with the NI PXIe-796xR FPGA modules.

Note Before configuring your NI 5791. you must install the appropriate software

and hardware. Refer to the NI FlexRIO FPGA Module Installation Guide and

Specifications for installation instructions.

Note For EMC compliance, operate this device according to the documentation.

Overview

The National Instruments VXIpc-870B Series embedded controllers

are flexible, high-performance Pentium III-based controllers in a

rugged package ideal for VXI systems. An NI VXIpc-870B Series

controller in a VXI chassis gives you direct control of VXI registers,

memory, interrupts, and triggers while maintaining compatibility

with the scores of software packages and tools available for general

market desktop PC computers.

The NI VXIpc-870B Series controllers come in four models with

various options that provide the most cost-effective VXI embedded

control solution available. Table 1 details the standard features of the

VXIpc-870B Series controllers. The VXIpc-870B Series controllers

require two VXI C-size slots. The VXIpc-871B and VXIpc-874B

include all the standard features, but also add an integrated 24X max

CD-ROM drive. The VXIpc-872B and VXIpc-875B also contain all

standard features, but instead of a CD-ROM drive,they offer one PCI

expansion slot.

If you require a solid-state storage medium for operation in harsh

environments,you can use the VXIpc-870B Series controllers with an

internal solid-state flash drive in place of the internal hard drive, or a

removable solid-state flash drive that you can install and remove

directly from the front panel.
