Using Waveform Mathematical Functions
When adding (CH1 + CH2), subtracting (CH1 – CH2, CH2 – CH1), multiplying (CH1 * CH2)
or dividing（CH1 / CH2 ) the input Waveforms of CHI and CH2, the Oscilloscope will
display the mathematical result Waveform M and the input Waveforms of CH1 and CH2 on
the screen. The Mathematical functions perform a point-to-point calculation on Waveforms
for CH1 and CH2.
To use a Mathematical function:
1.
2.

Press the MENU key and the function menu will display at the right side of the
screen.
Press the MENU UP or MENU DOWN key to select the WAVE MATH. Five
selectable items appear at the bottom of the screen.
Press F3 to select CH1+CH2 and the calculated waveform M (green) appears on the
screen. Press the F3 key to close the Waveform Calculation.
Press the OSC OPTION key and the following will be visible at the bottom left side of
the screen.
LEFT/RIGHT Time
UP/DOWN CHM Zero
Then press the OSC UP or the OSC DOWN key to adjust the vertical position of the
calculated waveform M displayed on the screen.
Press the OSC OPTION key and the following will appear at the bottom left side of
the screen.
LEFT/RIGHT Time Base
UP/DOWN CHM Vol
Press the OSC UP or OSC DOWN key to adjust the displayed amplitude of the
calculated waveform M.
