The quality of Gehua cable set-top box should be the number of signal parameters
45%---95% normal range,The television signals can be received better.
2 、 signal quality and signal intensity are two important parameters of TV signal. The national standard stipulates that the strength of CATV terminal signal is 60 to 75DB for general users. Cable system engineering technical specifications: non adjacent frequency system transmission signal strength should be 65 to 75DB; adjacent frequency system transmission signal strength should be 60 to 68DB.
The signal quality parameters of 1, Gehua cable set-top box is generally between 45% to 95% belong to the normal range, are better able to receive TV signals.
