EMC Test System Power Amplifier Checks

Ensuring the reliable performance of power amplifiers is critical for maintaining the integrity of electromagnetic compatibility (EMC) testing systems. In this paper, we outline a comprehensive procedure for evaluating the small signal performance of amplifiers. This procedure involves comparing current performance data against previously recorded benchmarks at five predetermined spot frequencies. By following these guidelines, technicians can identify potential faults and ensure the amplifier operates within its specified small signal range, thereby preventing damage to the spectrum analyzer.

Key equipment for this process includes a signal generator, directional coupler, and spectrum analyzer, with specific attention to staying below the 'No Damage Level' input power to protect the equipment. Detailed instructions and appendices provide additional support for executing these critical checks accurately.
