Satellite TV receiving antenna LNB regarding the certain receiving system in theoretically is a fixture,but in fact its value is drift because of receiving the working conditions change.Because LNB is different,this inspires the frequency and the frequency of the theoretically is different. In the actual safeguard work,the identical satellite signal,the intermediate frequency which obtains with the different receiving antenna is different,even more appearing the two frequency surpasses 2MHz,it must adjust the parameter establishment of the satellite TV decoder.

卫星电视接收天线LNB的本振频率对于一定的接收系统在理论上是一个固定值,但实际上其值受到工作环境变化的影响会出现漂移;其次,由于所选用的LNB不同,本振频率与理论值的频偏不同。在实际的保障工作中,接收同一卫星信号,用不同的接收天线得到的中频不同,严重时会出现二者的频偏相差超过2 MHz,这样在更换备用天线时必须调整卫星电视解码器的参数设置。
