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.
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.
PXI VSTs take advantage of the inherent timing and synchronization capabilities of PXI, providing subnanosecond synchronization for applications such as envelope tracking and multiple input, multiple output (MIMO).
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.
The baseband VST tightly synchronizes with the RF VST to subnanosecond accuracy to offer a complete solution for RF and baseband I/Q test of wireless chipsets using digital predistortion and envelope tracking techniques.
