      What Is a PXI Vector Signal Transceiver?

      The PXI Vector Signal Transceiver (VST) combines an RF and baseband vector signal analyzer and generator with a user-programmable FPGA and high-speed serial and parallel digital interfaces for real-time signal processing and control from baseband to mmWave.

      Measure From Baseband to mmWave

      The baseband VST tightly synchronizes with the RF VST to sub-nanosecond accuracy to offer a complete solution for RF and baseband I/Q test. The mmWave VST extends frequency coverage to support mmWave 5G and RADAR prototyping applications.

      Test Wide Instantaneous Bandwidth

      With 1 GHz instantaneous bandwidth for RF and baseband signal generation and analysis, VSTs are ideally suited for applications such as carrier aggregation, digital predistortion, and automotive radar testing.

      Perform Accurate EVM Measurements

      The combination of low phase noise, high linearity, and patented IQ calibration enables the VSTs to achieve better than -52 dB error vector magnitude (EVM) performance with higher order modulation schemes like 802.11ax 1024 QAM.

      Synchronize Multiple Instruments

      PXI VSTs take advantage of the inherent timing and synchronization capabilities of PXI, providing phase-coherent synchronization for applications such as envelope tracking and multiple input, multiple output (MIMO).

      User-Customizable FPGA

      The VST family basecard consists of a Xilinx Virtex-7 FPGA that you can customize to design application-tailored enhancements called FPGA extensions. You can develop these FPGA extensions using the LabVIEW FPGA Module to perform measurement acceleration, closed-loop tests, and complex algorithm engineering.
