Key Points: 
  Unlike Auto Scale, this function can solve the problem of signal overrange due 
to parameter settings and adjust the maximum mixing level according to the 
signal under measurement.  
  Unlike Auto, this function adjusts the signal within the current channel and 
does not modify the channel frequency setting. While, Auto will search for 
signal within the full frequency range and locate the signal at the center 
frequency.
