To verify the VSA, we setup the platform and execute the loopback test. The generated baseband IQ waveform will be sent to the radio platform, and RF output will feed into RF input. Then, the received IQ baseband waveform will be analyzed by the CSPLab VSA and Keysight 89600 VSA. By testing several waveform, we compare the EVM results from them. We can see that the EVM is about -39dB and they have almost the same performance. | |
