NI has announced a baseband model of the second-generation vector signal transceiver (VST). The PXIe-5820 module is the industry's first baseband VST with 1 GHz of complex I/Q bandwidth and is designed to address the most challenging RF front-end module and transceiver test applications, such as envelope tracking, digital predistortion, and 5G test.
The PXIe-5820 combines a wideband I/Q digitizer, wideband I/Q arbitrary waveform generator, and high-performance user-programmable FPGA into a single two-slot PXI Express module. With 1 GHz of complex I/Q bandwidth, the baseband VST suits a wide range of applications including baseband I/Q testing of wireless and cellular chipsets as well as envelope tracking of digitally predistorted waveforms for power amplifier, and generation and analysis of new wireless standards such as 5G, 802.11ax, and LTE-Advanced Pro.
The baseband VST is a vital part of the NI platform and ecosystem that engineers can use to build smarter test systems. These test systems benefit from more than 600 PXI products ranging from DC to mmWave. They feature high-throughput data movement using PCI Express Gen 3 bus interfaces and sub-nanosecond synchronization with integrated timing and triggering. Users can take advantage of the productivity of the LabVIEW and TestStand software environments, along with a vibrant ecosystem of partners, add-on IP, and applications engineers, to help dramatically lower the cost of test, reduce time to market, and future-proof testers for tomorrow's challenging requirements.
