What Is the Vector Signal Transceiver?

World’s First 1 GHz Bandwidth VST

NI’s second-generation PXI Vector Signal Transceiver (VST) offers 1 GHz of instantaneous RF bandwidth for signal generation and analysis. The PXIe-5840 VST combines a 6.5 GHz RF vector signal generator, 6.5 GHz vector signal analyzer, user-programmable Virtex-7 690T FPGA, and high-speed serial interface into a single 2-slot PXI module. Built on the LabVIEW reconfigurable I/O architecture, it delivers programming flexibility and cutting-edge RF hardware to help you develop the most challenging RF applications.
