Description

The Square Kilometre Array Observatory (SKAO) sets stringent requirements for electromagnetic compatibility (EMC) to ensure minimal radio frequency interference (RFI) from its equipment. This presentation outlines the comprehensive EMC emission testing methodology developed and implemented at RISE using Reverberation Chambers (RCs). Covering a frequency range from 300 MHz to 25.5 GHz, the tests utilize advanced instrumentation, real-time spectrum analysis (RTSA), and I/Q data sampling to identify and characterize emission culprits. The methodology includes chamber calibration, noise reduction, spectrum integration, and traceability mechanisms. Practical challenges such as auxiliary equipment leakage, Doppler effects, and data storage are addressed.
