1·Then a multifunctional, digital and portable field strength meter is designed based on this research.

在此基础上，设计了多功能、数字化、便携式场强仪。

2·An isotropic broadband field strength meter was used and the formula of calculating field strength is introduced.

测量采用各向同性的宽带场强计。本文还介绍了有关理论计算公式。

3·The calibration principle and method of the near region field strength meter are described, especially its auto calibration and test system and the study of software.

介绍了近区场强仪的核准原理和方法，着重介绍了近区场强议的自动校准测试系统和软件的研究。
