By deconstructing the VSG and VSA architecture into the core VSG/VSA software, cross-platform control interface, and radio platforms parts, we built up a cost-effective, flexible test platform. Since we master the core technology of Wi-Fi 6 VSG and VSA, we can ensure the correctness of the signal generation and try our best to improve the analysis performance. In addition, we can also develop more analysis functions and applications to achieve faster and more accurate measurement. On the other hand, because different radio platforms have different interfaces, specifications and performances, we develop the cross-platform control interface to be able to integrate the core VSG/VSA software and the radio platforms, and built the power calibration process for the USRP SDRs, enabling it can perform power measurement. To sum up, the proposed cost-effective test platform has been tested and verified by the commercial instruments, and can be used in R&D test or the mass production phase. In the future, we will integrate more radio platforms and expected to upgrade the core VSG/VSA software for supporting Wi-Fi 7.
