In this function, use the addition, subtraction, multiplication and FFT function to operate 
and analyze the waveform. 

Select the operate type in the 

Operate

 menu. Select source A and B. Then adjust the 

vertical scale and offset to view the math channel clearly. The mathematic result can be 
measured by the measure and the cursor.
