To add, subtract, or multiply waveforms
1 Press Math.
2 In the Math menu, press Operate to select:
• 1+2
• 1- 2
• 1x2
3 To invert the result of the addition, subtraction, or multiplication (with
respect to the reference level), select Invert to toggle between “ON” and
“OFF”.
To display the frequency domain using FFT
The FFT math function mathematically converts a time- domain waveform
into its frequency components. FFT waveforms are useful for finding the
harmonic content and distortion in systems, for characterizing noise in DC
power supplies, and for analyzing vibration.
To display a waveform’s FFT:
1 Press Math
.
2 In the Math menu, press Operate until “FFT” is selected.
3 In the FFT menu, press Source until the desired input channel is
selected.
NOTE
The FFT of a waveform that has a DC component or offset can cause incorrect FFT
waveform magnitude values. To minimize the DC component, choose AC Coupling on the
source waveform.
To reduce random noise and aliasing components (in repetitive or single-shot waveforms),
set the oscilloscope acquisition mode to averaging.
