Math Operation
Press Math in the waveform control area (Wave) on the front panel to open the
math operation menu. You can also tap the function navigation icon at the
lower-left corner of the screen to open the function navigation. Then tap the "Math"
icon to open the math operation menu. This oscilloscope supports four math
operations: Math1, Math2, Math3, and Math4. The following section takes Math1 as
an example to introduce the math operation in detail.
Press Math  Math1  Operator to select the desired math function. Press
Operation continuously to enable or disable the operation. When enabled, the
results of math operation are displayed with purple waveforms on the screen, and
the math operation formula, vertical scale, and other parameters (the displayed data
parameters are different for different math operations) are displayed at the bottom
of the screen. The results of the math operation can be further measured. This
oscilloscope supports enabling the four math operations at the same time, as shown
in the figure below.
MSO7000/DS7000 series can realize multiple math operations between waveforms of
different channels, including
 arithmetic operations (A+B, A-B, A× B, and A/B)
 FFT operation
 logic operation: A&&B, A||B, A^B, and !A
 function operation: Intg, Diff, Sqrt, Lg, Ln, Exp, Abs, and AX+B (linear function)
 math filter: low-pass filter, high-pass filter, band-pass filter, and band-stop filter
Note: When you select the source, only the enabled channel is available.
Addition
Adds the waveform voltage values of signal source A and B point by point and
displays the results.
Press MATH  Math1  Operator to select "A+B":
 Press Operation continuously to enable or disable the addition operation
function.
 Press SourceA and SourceB respectively, and rotate the multifunction knob
to select the channel for SourceA and Source B. Then press down the knob
