Quick Editing

AWG610 Arbitrary Waveform Generator User Manual

3-93

When you cancel the changes and quit the quick editor, the instrument copies the

data in the undo buffer back to the edit buffer (and also to the waveform memory

if the data is being loaded), and then terminate the quick editor.

About Smoothing

Quick Edit performs expand, shrink, or shift the cursor-to-cursor data. Conse-

quently, if nothing is processed, a gap may be produced between the changed and

unchanged portions. To link the entire data smoothly, smoothing is performed.

Cursor-to-cursor points move in response to turning the general purpose knob.

Also for the unchanged portions, the smoothing moves the positions so that the

entire data is linked smoothly. This occurs throughout the range specified with

the Smoothing Points side menu. The amount of shift is calculated internally to

enable a smooth link and to minimize the effect on the unchanged portions. The

calculation uses a cubic polynomial for the horizontal amount and sine for the

vertical amount.

The value of the points mentioned above are usually nonintegers. That is, the

resulting horizontal coordinates of the points are not integers. The values at the

coordinates (integers) on the horizontal axis of the waveform data are sequential-

ly obtained using the interpolation you specified with the Interpolate side menu.

Quick Controls

To enable the Quick Edit mode, press the QUICK EDIT front-panel button, as

shown in Figure 3–21.
