Waveform Differentiation (Optional)
Description
The math waveform is derived from the sampled waveform. Since the resultant
waveform is a derivative waveform, its vertical scale is in vertical units per
second (its horizontal scale is in seconds).
Operation
To obtain a derivative math waveform:
1. Connect the waveform to the desired channel input and select that channel.
2. Adjust the vertical and horizontal scales and trigger the display (or press
AUTOSET).
3. Press MORE
➞ Math1, Math2, or Math3 (main) ➞ Change Math
Definition
(side) ➞ Single Wfm Math (main). See Figure 3–73.
4. Press Set Single Source to
(side). Repeatedly press the same button (or use
the general purpose knob) until the channel source selected in step 1 appears
in the menu label.
5. Press Set Function to
(side). Repeatedly press the same button (or use the
general purpose knob) until diff appears in the menu label.
6. Press OK Create Math Wfm
(side) to display the derivative of the
waveform you input in step 1. Use the Vertical SCALE and POSITION
knobs to size and position your waveform as you require.
