DTMB广播发射及覆盖测试解决方案

● Supports demodulation analysis of all DTMB national standard (GB 20600-2006) modes (such as 4QAM-NR, 16QAM, 64QAM, etc.)；
● High-precision measurement of key indicators such as MER (Modulation Error Rate), BER (Bit Error Rate), and EVM (Error Vector Magnitude)；
● Real-time spectrum analysis for quick interference source location；
● Portable design suitable for laboratory, transmitter station, and field testing；
● Combined with maps, realizes automated road testing and real-time recording of field strength, carrier-to-noise ratio, packet error rate, etc；
● Supports big data analysis, automatically generates heat maps, and identifies weak coverage areas；
● Provides optimization suggestions, such as adjusting transmission power, antenna azimuth, or adding relay stations.
