You can 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 invert, add, subtract, divide, and multiply waveform
math features. If your oscilloscope is equipped with Advanced DSP Math
(optional on TDS 620A & TDS 640A), see 

Fast Fourier Transforms on

page 3-38, 

Waveform Differentiation on page 3-150, and Waveform Integra-

tion on page 3-154.

To perform waveform math, press the MORE button to bring up the More
menu (Figure 3-84). The More menu allows you to display, define, and manip-
ulate three math functions.
