| Abstract: | The design of a portable peak power meter is introduced in this paper. It presents the schematic diagram and working theory of the portable peak power meter. The principles and realizations of microwave disposal, peak demodulation, random sampling and data disposal, automatic frequency measurement, frequency response error compensation, and the software of calibration and measurement are emphatically expounded. The portable peak power meter which is designed according to these techniques can measure RF-signal power accurately and quickly. |
