Avg Mode 
Sets the type of termination control used for the averaging function. This determines the 
averaging action after the specified number of measurements (see 
Avg Number) has been 
reached.
Exponential  Sets the 
Avg Mode 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.
Repeat  Sets 
Avg Mode to the repeat function. Repeat averaging shows resulting data after 
the selected number of sweeps has been averaged, then clears the data before repeating 
the process.
NOTE With large average counts and/or slow traces, the trace from the last 
completed result remains on the display while 
Repeat averaging is
