By combining the NI PXIe-5641R RIO IF transceiver with the NI PXI-5600 downconverter and NI PXI-5610 upconverter, you can create a field-programmable gate array (FPGA)-enabled software-defined radio on the PXI platform covering frequencies from 250 kHz to 2.7 GHz with 20 MHz of real-time bandwidth. The NI PXIe-5641R features 14-bit, 100 MS/s analog-to-digital converters (ADCs) with built-in 20 MHz bandwidth digital downconverters, and 14-bit 200 MS/s digital-to-analog converters (DACs) with built-in 20 MHz bandwidth digital upconverters. This architecture efficiently delivers I/Q data to the Virtex-5 SX95T FPGA on the module for analysis, demodulation, and signal processing tasks using the NI LabVIEW FPGA Module so that you can create your own unique software-defined radios.

Transceiver
20 MHz bandwidth IF transceiver with DSP-optimized Xilinx Virtex-5 SX95T FPGA (NI PXIe-5641R) 780710-01
Features intermediate frequency (IF) inputs and outputs for interfacing with analog upconverters and downconverters to acquire and generate RF signals. It also has a powerful LabVIEW-programmable FPGA capable of performing complex modulation and signal processing in hardware at high rates with low latency, both requirements of software-defined radios.

Downconverter
2.7 GHz RF downconverter (NI PXI-5600) 778283-01
Accepts RF signals from 9 kHz to 2.7 GHz with up to 20 MHz bandwidth then downconverts them to 15 MHz IF signals, optimal for interfacing with the PXIe-5641R.

Upconverter
2.7 GHz RF upconverter (NI PXI-5610) 778737-01
Accepts IF signals from the output of the NI PXIe-5641R at 25 MHz with up to 20 MHz bandwidth, then upconverts them to RF signals from 250 kHz to 2.7 GHz.

Chassis
8-Slot PXI Express chassis (NI PXIe-1062Q) 779633-01
A PXI Express hybrid-capable chassis accepts both PXI Express and PXI modules, and offers a small footprint solution for software-defined radio.

Controller
NI PXIe-8108 Dual Core Controller Downgrade to Windows XP 781033-01
A high-performance PXI Express controller allows you to complement the fixed point signal processing on your FPGA with floating point processing on a high-speed dual-core CPU.
2 GB DDR2 RAM 780446-2048
Additional host memory for high-bandwidth signal processing.

Software
Required Software
LabVIEW Professional Development System, Windows, Include 1 Year SSP 776678-35
Speed up your development with advanced software engineering tools. LabVIEW Professional is the choice for software developers who need source code control integration, memory profiling tools, and application distribution.
LabVIEW FPGA Module, Include 1 Year SSP 778694-35
Use LabVIEW embedded technology to extend LabVIEW graphical development and target field-programmable gate arrays (FPGAs) on NI reconfigurable I/O (RIO) hardware.
Optional Software
NI Modulation Toolkit For LabVIEW 778786-35
Extend the capabilities of LabVIEW with host-side functions and tools for, analyzing, processing and visualizing standard and custom digital or analog modulation formats.
Spectral Measurements Toolkit, WIndows 778453-35
This toolkit provides flexible host-side spectral measurements functions to measure parameters such as adjacent-channel power, occupied bandwidth and more.

Cables
SMA to SMA Cable (15cm) 763443-01
Each software-defined radio requires two SMA to SMA cables to connect IF signals between modules, and one SMA to SMA cable to share a common 10 MHz reference clock between the upconverter and downconverter.
SMA to SMB Cable 779766-01
Each software-defined radio requires one SMA to SMB cable to lock the NI PXIe-5641R to the 10 MHz reference clock shared between the upconverter and downconverter.

Chassis Power
Power Cord, AC, U.S., 120 VAC 763000-01
Power Cord, 240V, 10A, North American 763068-01
