Who can perform acceptable calibration for FCC proof-of-performance (POP) testing?

The correct choice is that the manufacturer or an approved service center can perform acceptable calibration for FCC proof-of-performance (POP) testing. This is because FCC regulations dictate that equipment used to ensure compliance with performance standards must be calibrated by qualified entities. Manufacturers and approved service centers possess the necessary expertise, tools, and certification to conduct such calibrations correctly, ensuring both accuracy and compliance with regulatory standards.

Calibration performed by these qualified entities is essential as it assures that the testing results are valid, reliable, and meet the standards set by the FCC, thereby maintaining the integrity of the equipment's performance. Each manufacturer typically has specific calibration protocols, and service centers are trained to follow these procedures to guarantee consistency across different tests and devices.

While technicians, customers, or independent contractors may have the skills or knowledge to conduct various maintenance tasks, they do not always possess the accreditation or specialized equipment required by the FCC for official calibration purposes. This is why only manufacturers or designated service centers are recognized as the acceptable options for performing this critical task.
