Signal Intelligence

There is a difference between Electronic Warfare (EW) and Signal Intelligence (SIGINT).

  • EW can be considered an ‘offensive strategy’ – where our military jams the transmissions of the enemy, and can be used for Cyber-warfare.
  • SIGINT can be considered a ‘defensive strategy’ – where our military eavsdrops, detects, and anlyzes the transmissions of the enemy.

Signal Intelligence requires RF instrumentation that provides a wide RF Bandwith (BW), broad Instantaneous BW, improved Displayed Avg Noise Level (DANL), along with Real-time (RT) Signal Analysis with the fastest Probability-of-Intercept (POI) to capture intermittent and low energy interference.

  • Wide RF BW ensures monoriting more of the occupied RF Spectrum
  • Broad Instantaneous BW to analyze more of the RF Spectrum all at once
  • Improved DANL enables capture of low energy interfence near the Noise Floor
  • RT Signal Analysis with fast POI enables ‘gap-less’ acquisition of intermittent signals

Combining the NI PXIe-5668 and PXIe-7976 provides 63,550 DSP Slices for unmatched Signal Processing capability.

  • POI for the PXIe-5668 and PXIe-7976 is 20 μsec to meet ITAR regulations.
    If you require better than this specification please contact NI, which can provide algorithms that improve upon this time to below 1 μsec.
  • Phase Coherent Synchronization capable for MIMO and Radar Prototyping
  • Add NI RAID-Array for Full-bandwidth Streaming with Record & Playback

NI Vector Signal Transceiver (VST) Line – up to 44GHz

Combining the signal analysis capability of a VSA along with the signal generation capability of a Vector Signal Generator (VSG) and a user-programmable FPGA provides the end-user with additional test capabilities all in a small form-factor instrument.

NI introduced the world’s first PXIe VST in 2012 – which revolutionized the way high-performance RF test sets were developed, offering the dependability of calibrated RF measurements, the flexibility of user-programmable inline processing and the ability to program in LabVIEW or leverage existing VHDL IP.

In 2019 NI extended the capability of its VST line to address even more Radar, SATCOM and 5G frequencies, helping address the schedule, cost-of-test and quality issues inherent in the development of complex transmit/receive systems.

The PXIe-5831 VST combines a PXIe-5820 with a PXIe-3622 vector signal up-/down-converter for direct RF generation and analysis from 5 to 21 GHz. Modular mmWave heads further expand coverage to include frequencies from 23 to 44 GHz with integrated and calibrated switching for up to 32 channels. This enables multichannel beamformer and phased-array measurements without the need for additional hardware.

The PXIe-5831 complements NI’s modular instrumentation portfolio of more than 600 PXI/PXIe products – ranging from DC to mmWave.

It also offers NI platform features such as high-throughput data movement using PCI Express Gen 3 bus interfaces and performs sub-nanosecond synchronization across PXI modules with integrated timing and triggering. Users can take advantage of the productivity of LabVIEW software, AWR software, and the flexibility of the LabVIEW FPGA Module along with a vibrant ecosystem of partners, add-on IP and applications engineers. These benefits help them adapt to fast-changing technology and demanding technical requirements so they can deliver new systems on time and on budget.
