| Abstract: | The analysis of radio signal propagation in free space and the calculation of field strength in received end are presented. A novel field strength tester with high-precision, portable type and stable properties is detailed. This system, with MSP430G2553 as the core, include amplifier, detection circuit and A/D convener. The digital signal from A/D converter output to LCD12864 and display the result. The measure results show that the system has good precision. |
