Math Functions
The Math menu lets you display math functions on oscilloscope
channels. You can:
• subtract (–) or multiply (*) the signals acquired on
oscilloscope channels 1 and 2, then display the result.
• integrate, differentiate, perform an FFT, or the square root
function on the signal acquired on any channel or on math
functions 1 * 2, 1 – 2, or 1 + 2, then display the result.
To access math functions:
1 Press the Math key on the front panel to display the
Waveform Math Menu.
2 Press the Function sofkey and use the Entry knob (or keep
pressing the Function sofkey) to select the desired math
function.
After selecting a math function, softkeys for changing that
math function’s settings appear in the Waveform Math Menu.
Math Operating Hints
If the oscilloscope channel or math function is clipped (not fully displayed on
screen,) the resulting displayed math function will also be clipped.
Once the function is displayed, the oscilloscope channel(s) may be turned off for
better viewing.
The vertical scaling and offset of each math function can be adjusted for ease of
viewing and measurement considerations.
Each function can be measured in the Cursors and Quick Meas menus.
