NI (National Instruments, NI), a supplier dedicated to providing software-centric platforms designed to help users accelerate the development and performance of automated test and automated measurement systems. The company today announced the PXIe-5831 Vector Signal Transceiver (VST), which further addresses time-to-market challenges for X-band, Ku-band and Ka-band radar and satellite communications (SATCOM) components and systems.

　　To meet the growing demand in areas such as electronic battlefield and satellite communications (SATCOM), spectrum utilization is becoming increasingly tight, and engineers need to prototype, validate, and test radar as well as SATCOM systems in higher frequency bands in less time. the PXIe-5831 VST features a modular millimeter-wave header and extends the VST family of products to up to 44 GHz. it provides a new level of performance for signal generation and signal processing, and provides a new level of performance for signal generation. 44 GHz. It provides 1 GHz of instantaneous bandwidth for signal generation and analysis and features a high-performance FPGA so users can perform measurements, real-time signal processing, and high-speed data transfer faster and more efficiently.

　　Luke Schreier, vice president and general manager of NI's Defense, Aerospace and Government business, said, "The VST revolutionized the development of high-performance RF test routines when it was first released in 2012, providing calibrated, reliable RF measurement data and flexible, user-programmable in-circuit signal processing in addition to the ability to Extending these capabilities to additional radar and satellite communication frequencies can help the field address the timeline, test cost and quality issues common to the development of complex transceiver systems, as well as programming in LabVIEW or utilizing existing VHDL IP. From the company's perspective, these technologies are not only applicable to radar and satcom, but also to the commercial 5G space, enabling us to provide more efficient support for this product. "

　　The PXIe-5831 combines the PXIe-5820 baseband VST with the PXIe-3622 vector signal up-converter/down-converter to directly generate and analyze RF signals in the 5 to 21 GHz range. The modular millimeter-wave RF head not only further extends frequency coverage to 23 to 44 GHz, but also features integrated and calibrated switches to support up to 32 channels. This allows engineers to perform multi-channel beamformer and phased array measurements without additional infrastructure.

　　The PXIe-5831 is a new addition to NI's modular instrument portfolio, which encompasses more than 600 PXI products covering the frequency range from DC to millimeter wave. the PXIe-5831 also features NI platforms, such as high-throughput data transfers based on the PCI Express Gen 3 bus interface and sub-nanosecond synchronization between PXI modules through integrated timing and triggering functions. sub-nanosecond synchronization between modules. As a result, users of the PXIe-5831 can also take full advantage of the functionality of LabVIEW software, the flexibility of LabVIEW FPGA modules, and the large ecosystem of partners, add-on IP, and application engineers. These advantages help them adapt to rapidly changing technologies and demanding technical requirements to deliver new systems on time and within budget.
