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 waveĆ
form you input in step 1.
You should now have your derivative math waveform on screen. Use the
Vertical SCALE and POSITION knobs to size and position your waveĆ
form as you require.
Automated Measurements of a Derivative Waveform
Once you have displayed your derivative math waveform, you can use
automated measurements to make various parameter measurements. Do
the following steps to display automated measurements of the waveform:
1. Be sure MORE is selected in the channel selection buttons and that the
differentiated math waveform is selected in the More main menu.
2. Press MEASURE ➞ Select Measrmnt (main).
