Procedure
1.
Press
DISPLAY
.
2.
Press the
Interpolation
soft key. The interpolation selection menu appears.
3.
Press one of the soft keys from
OFF
,
Sine

If the display mode is X-Y or T-Y&X-Y, press the Next 1/2 soft key to display the
Interpolation menu.
Explanation
Interpolation
Any area along the time axis having less than 1000 points in 10 divisions (less than 500
points in the Z1 and Z2 window when displaying Main&Z1&Z2) is recognized as an
interpolation area. If you leave interpolation off, these points will appear as discrete dots
(so that the display will show gaps between dots or vertical lines).
If you set interpolation on, the SL1400 will connect the points. Three following
interpolation methods are available.
Sine (
):
Interpolates between two points using the sin(x)/x function.
Line (
):
Linearly interpolates between two points.
OFF (
):
No interpolation.

• When the Area Is Not an Interpolation Area
If interpolation is set to Sine or Line, the instrument draws lines between points that
are aligned vertically. If the number of data points is greater than or equal to 2002, P-
P compression is performed (maximum and minimum values are determined at
certain intervals), and two points are displayed on a single vertical line (1 raster).
