AMPT 
 
Set the amplitude parameters of the analyzer. Through modifying these 
parameters, signals under measurement can be displayed in a proper mode for 
easier obsercation and minimum error.  
 
 
Auto Scale 
 
This function enables the readout resolution of the Y-axis to be the maximum 
possible while at the same time ensures the completeness of the signal. When 
enabled, the system sets the reference level automatically in order to place the 
peak of the signal within the topmost grid for easier observation of the trace.
