Explanation
Interpolation Method
Set the method by which sampled data are connected to display the waveform. If the
Main and ZOOM1 or ZOOM2 display record length is as follows, the sampled data are
only connected in the vertical direction. There is no difference between Pulse, Line, and
Sine.
• 4 kW
ord, 5 kWord
• 10 kWord or higher
If the display record length is other than the above, new interpolation points are
generated between sampled data according to the specified interpolation method, and
the interpolation points are connected in the vertical axis direction.
OFF: No interpolation.
Pulse:
Interpolates between two points by drawing a horizontal line to the time of the
next data point, then connecting the end of the horizontal line to the next data
point with a vertical line.
Line: Linearly interpolates between two points.
Sine: Interpolates between two points using the (sin x)/x function.
