Performing Waveform Math

Clipping a Waveform

The Math Clip command clips the present waveform data to the specified Y value.

To perform the clipping function, you must first select the area of the waveform to be clipped using the Y markers. To clip a waveform:

1 Turn on the Y markers using the Edit Y Markers command or click

 

the Y Markers icon.

2Position the markers to specify the minimum and maximum Y values. Click the Thumbtack icon to set the markers.

3Click the ‘edit select’ icon, then click and drag your mouse to highlight the area to be clipped.

4Select Math Clip from the Menu Bar. The area above and below the markers will be clipped.

Using Absolute

The Math Absolute command changes the sign on all negative Y-value points so that the waveform contains only positive points. Select the waveform or segment on which to perform this operation, then select this command from the Math menu.

Inverting a Waveform

Math Invert causes the waveform to be flipped vertically. Each point in the selected waveform is multiplied by -1 to get the inverted values. Select the waveform or segment on which to perform this operation, then select this command from the Math menu.

Mirroring a Waveform

The Math Mirror command horizontally rotates the waveform about the center of the selected segment. If the selected waveform contains 2000 points, the rotation would occur at point 1000. Select the waveform data or segment on which to perform this operation, then select this command from the Math menu.
