Avg Mode 
Sets the type of termination control used for the averaging function. This determines the 
type of averaging that will be used for the specified number of measurements.
Off  Turns averaging functions off.
Exponential  Sets the averaging function to exponential. With exponential averaging mode, 
each successive data acquisition is exponentially weighted and combined with the existing 
average. This weights new data more than the old data, which facilitates tracking of slow 
changing signals.
Max Hold  In 
Max Hold the analyzer maintains and displays a max hold trace, which 
represents the maximum data value on a point-by-point basis of the new trace data and
