ABSTRACT: As highlighted in this SATELLITE 2025 demonstration, the Maury Microwave ACE9000 Advanced Channel Emulator can emulate and apply satellite-induced impairments such as compression, IMUX, and phase noise to any communications signal. The impaired signal is then demodulated by a vector signal analyzer (VSA), which connects to a monitor to display key performance metrics for signal integrity, including constellation diagrams and error vector magnitude (EVM). By analyzing these parameters, engineers can assess the impact of satellite payload impairments on signal performance under realistic operational conditions.
