在对小功率调频广播发射机的维修中 ,除了用到高频示波器、中小功率计和假负载外 ,还要用到测量毫瓦级的小功率计。但常因多数基层广播台站缺少这些专用仪器 ,特别是小功率计等必备仪器 ,而给发射机的维修测试工作带来了不便。我们利用各基层台站现有的有线电视场强仪 ,来作发 In the maintenance of low-power FM radio transmitters, in addition to the use of high-frequency oscilloscopes, small and medium-sized power meter and false load, but also to measure milliwatts of small power meter. However, most of the grass-roots broadcasting stations lack these special instruments, especially the low-power meters, which often cause inconvenience to the maintenance and testing of transmitters. We made use of the existing cable television field strengths at the grassroots stations
