Signal level meter is mainly to construct and maintenance of the analog and digital television network, which can be easily to analyze the network fault and guarantee the common operation of network with the quick average power . It is more easily applicable to the digital, analog mixed-net network.Meter can measure C/N,Trunk line Voltage, V/A, The equipment also can measure the average of DVB-C digital signal,MER,BER,especially appliance to the measurement and setting for the fixed-network of analog and digital TV.
