摘要
提出了一种便携式真峰值功率计的设计原理,详细介绍了便携式真峰值功率计的基本结构及其工作过程,论述了峰值检波、随机采样、自动测频、频响误差补偿技术与校准、测量软件的实现原理并给出了实现方案。按照该方案设计的便携式峰值功率计实现了对射频信号功率的准确快速测量。
The design principle of a portable true peak power meter is put forward. The schematic diagram and working procedures of the portable tree peak power meter are introduced in detail, The implementing principle and schemes of peak detection, random sampling, automatic frequency measurement, frequency response error compensation, and the software of calibration and measurement are emphatically expounded. The portable tree peak power meter designed according to this strategy measures RF - signal power accurately and quickly.
