Parameter Description
HorizontalUnit Specifies the horizontalaxis data point unit (points or time) used to
represent the position along the horizontal axis. The default setting is points.
Update Mode Specifies when output memory is updated. In Auto the output waveform is
automatically updated in the waveform memory as you change the
waveform in the editrot. Changes are not saved to the original file, unless
you manually save the changes.
Note: Auto mode only works when the file you currently editing is also
loaded in the waveform memory.
Selecting Manual causes the instrument to update the output waveform only
when the contents of the waveform file on the disk is changed by the save
function of the editor.
In Auto mode, you cannot edit waveform while the instrument is reloading.
The longer the waveform, the longer you may have to wait to return to edit
mode. Manual mode allows faster editing when you have a large number of
points in the data file.
Cursor Link Specifies whether to link cursor movement when two or three edit windows
are open. Selecting ON causes the cursors in the inactive windows to be
linked to their respective cursor in the active window. The default value is
Off.
If a linked cursor reaches either end of its data record before the active
window cursor, the linked cursor remains at the data record end. This can
result in changes to the relative cursor positions and edit areas between the
editor windows.
Grid Specifies whether to display a grid. Selecting On displays a grid in all open
Graphical Waveform Editor windows. Selecting Off disables grid display.
The default value is Off. The grid is not displayed in the Tabular Waveform
Editor window or the Pattern Editor window.
The instrument automatically sets the grid interval.
Interpolation Specifies whether to enable waveform display interpolation when the density
of points decreases due to zooming. Selecting On specifies that the
instrument use the algorithm aX 2 + bX + c
to interpolate the waveform
level between data points.
Selecting Off displays the data point values as they are. The default value is
Off.
This function is provided to display a smooth waveform from data that
contains relatively few data points in a cycle (such as in a disk test
waveform). Note that this function may cause reduction in the linearity of
some types of waveforms, such as a ramp waveform.
