Waveform Math
The digitizing oscilloscope allows you to mathematically manipulate your
waveforms. For example, you might have a waveform clouded by background
noise. You can obtain a cleaner waveform by subtracting the background noise
from your original waveform.
This section describes the standard waveform math features.
To Use Single Wfm Math
The More menu (see Figure 3–77) allows you to display, define, and manipulate
math functions. To create a math waveform based on a single source waveform:
1. Press MORE
➞ Math1, Math2, or Math3 (main) ➞ Change Math
waveform definition
(side) ➞ Single Wfm Math (main).
2. To define the source waveform, press Set Function to
(side) repeatedly to
cycle it to the desired channel or reference waveform.
