Basic Operations 
 
MSO4000/DS4000 supports the basic operations (addition, subtraction, 
multiplication and division) on the analog channels. 
 
You can perform the basic operations following the steps below. 
1.  Specify the basic operation 
Press MATH  Operate, turn the multi-function knob   to select the desired 
basic operation (addition, subtraction, multiplication or division) and press the 
knob. You can also press Operate continuously to switch the current operation.  
  A+B: addition. Add the waveform voltage values of signal source A and B 
point by point and display the results. 
  A-B: subtraction. Subtract the waveform voltage values of signal source B 
from that of signal source A point by point and display the results. 
  AxB: multiplication. Multiply the waveform voltage values of signal source A 
and B point by point and display the results. 
  A÷B: division. Divide the waveform voltage values of signal source A by that 
of signal source B point by point and display the results. It can be used to 
analyze the multiple relationships of waveforms in two channels.  
Note: When the waveform voltage value of signal source B is 0, the result 
of the division is treated as 0. 
 
2.  Specify the signal source A and signal source B 
1)  Press Source A, turn the multi-function knob   to select the desired 
channel and press the knob. You can also press Source A continuously to 
switch the channel currently selected. The channels available are CH1, CH2, 
CH3 and CH4. 
2)  Press Source B and use the same method to specify the signal source B.  
 
3.  Adjust the vertical scale and vertical position 
Press 
 and   respectively; turn the multi-function knob   to adjust the 
vertical scale and vertical position of the math operation waveform. Please refer 
to “MATH Waveform Vertical Control”. 
 
4.  Adjust the horizontal time base and horizontal position 
Use HORIZONTAL 
  SCALE and HORIZONTAL    POSITION to adjust 
the horizontal time base and horizontal position of the math operation waveform
