It can conveniently measure and show the average power of digital TV channel, signal level of analog TV channel(Visual carrier frequency, Audio carrier frequency, ? ) , single frequency level, sound monitor, channel spectrum etc.
Meanwhile, S220D(DS2100Q) signal level meter adds the function of signal quality analysis. According to the reference threshold setting in advance, it can determine the signal quality. People in different areas have their own test channels with the function of FAV LIST. Those two functions make it more convenient for users.
