Description

technical field [0001] The invention relates to a wireless broadcast signal monitoring system, in particular to a broadcast signal remote monitoring terminal for effectively monitoring the broadcast quality of the broadcast signal. Background technique [0002] In order to ensure the broadcasting quality of broadcasting signals, including FM and AM frequency bands, radio stations need to monitor the signal parameters within the coverage of the signal. The main monitoring parameters of FM are RF field strength, 19KHZ pilot signal, modulation degree, and AM is RF field strength and Effective monitoring of the modulation range. Currently, there are generally two ways to monitor broadcast signals. One is to manually carry special instruments and perform regular or irregular manual tests at monitoring points within the signal coverage. This method has a large workload and high monitoring cost, and because it is intermittent monitoring, it is impossible to know the real broadcast...
