Explanation
Interpolate
Any area along the time axis having less than 500 points per 10 divisions (less than 250
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, however, the DL1640/DL1640L will connect the points. Three interpolation settings
are available.
Sine (
): Interpolates between two dots using a sin x/x function.
Line (
): Interpolates between two dots in a straight line.
PULSE (
): Draws a horizontal line to a point directly above or below the next data
point and then interpolates using two dots so that the end of the
horizontal line is connected to the next data point by a vertical line.
OFF (
): No interpolation
