NI 5791R RF Transceiver Adapter Module

The NI 5791 is an RF transceiver adapter module designed to work in conjunction with your

NI FlexRIO™ FPGA module. The NI 5791 features the following connectors and chips:

• 2-channel, 130 MS/s analog-to-digital converter (ADC) with 14-bit accuracy

• 2-channel, 130 MS/s (520 MS/s after interpolation) digital-to-analog converter (DAC)

with 16-bit accuracy

• LO input and LO output connectors to support LO sharing for multiple-channel applications

• Timing chip with clocking options from the backplane and the front panel

• Programmable attenuators

• Selectable receive and transmit filters

• The following front panel connectors:

– RX IN

– LO OUT

– CLK IN

– CLK OUT

– LO IN

– TX OUT

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.
