By combining the NI PXIe-5641R RIO IF transceiver with the NI PXI-5600 downconverter and NI 8260 high-speed data storage module, you can create a field-programmable gate array (FPGA)-enabled spectral monitoring or signal intelligence system 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 two independent 14-bit, 100 MS/s analog-to-digital converters (ADCs) with built-in 20 MHz bandwidth digital downconverters. 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. For continuous logging, you can stream 20 MHz of RF bandwidth (100 MB/s) per FPGA module to a RAID-based hard disk such as the NI 8260 for several hours.

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 demodulation and signal processing in hardware at high rates with low latency, both benefits for systems which much process high bandwidth signals and react to changes quickly.

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.

Chassis
18-Slot PXI Express chassis for high bandwidth applications (NI PXIe-1075) 780291-01
A PXI Express hybrid-capable chassis accepts both PXI Express and PXI modules, and offers a small footprint signal intelligence applications. The NI PXIe-1075 extends the total system bandwidth from 3 to 4 GB/s over the NI PXIe-1065.
PXIe-1065, 18-Slot 3U PXIe/PXI Chassis 779730-01

Controller
NI PXIe-8108 Dual Core Controller Downgrade to Windows XP 781033-01
2 GB DDR2 RAM for PXI(e)-8101/02/08 and PXI-8110 Controllers 780446-2048
4 GB DDR2 RAM for PXI(e)-8101/02/08 and PXI-8110 Controllers 780446-4096

Storage
High-speed data storage (NI 8260) 780980-01
The NI 8260 is a RAID-based 4-drive high-speed data storage module with a total capacity of 1 TB. It is capable of recording 20 MHz of RF bandwidth for over 2.5 hours.

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
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 downconverter requires one SMA to SMA cable to connect the IF signals between the NI PXI-5600 and the NI PXIe-5641R. To synchronize two downconverters, you need an additional SMA to SMA cable to share a common 10 MHz reference clock between them.
SMA to SMB Cable 779766-01
Each NI PXIe-5641R requires one SMA to SMB cable to lock to the 10 MHz reference clock of the downconverter.

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