ELECTROMAGNETIC POWER MEASUREMENT AND REPORTING

摘要

A method to measure and report electromagnetic radiation power includes receiving electromagnetic radiation and generating an electrical signal having a magnitude based on the power of the electromagnetic radiation. An adjustable gain may be applied to the electrical signal to generate an amplified electrical signal that may be sampled to generate a digital sample. The adjustable gain may be controlled based on the value of the digital sample and the digital sample may be associated with a gain value. One or more calibration factors may be selected based on the gain value associated with the digital sample and the selected calibration factor(s) may be used to calculate the power of the electromagnetic radiation.
