The developed SDR-based VSG/VSA platform for 4G LTE, NB-IoT, Wi-Fi, and 5G NR is an open-platform testing equipment, which can connect our core software with a variety of hardware platform via interface firmware. The disruptive innovation may occurs by breaking the high price of existing instruments and brand-bonding drawback of their hardware and software.

Through years of deep penetration of wireless communication measurement technology, we have accumulated many core technologies and have a number of signal processing, RF imperfection estimation and adjustment related patents. By the combination of the core VSG/VSA software, the related estimation/adjustment technology, and the SDR make this open-platform both affordable and with high performance.

The cost-effective open-platform vector signal tester is based on the SDR with self-developed VSG/VSA software. Through it, we can develop some customized measurement applications and also reduce the cost on testing and measurements. In the wireless communication industry, it is applicable as follows:
Talent cultivation: teaching/research,
R&D verification: algorithm/prototype verification,
Production line test: conformance test.
