Start Point and End Point (Start Point/End Point)
You can set the start and end points of the X-Y waveforms on the T-Y waveforms.
Selectable range: ±5 div from the center of the T-Y waveform window
• Scope mode: Set the positions in divisions.
• Recorder mode: Set the positions in terms of the time (ddhhmmss) corresponding to divisions.
The start and end points are similar to the settable range of the cursor display position in cursor measurement.
For details, see “Selectable Range of Cursor Positions.”
Linking Start and End Points
You can adjust the start and end points without changing the interval between them.
Interpolation Method (Dot Connect)
In interpolation zones in the X-Y waveform display,
*
Xviewer can display waveforms by interpolating between
sampled data points.
* Interpolation zone refers to the condition in which a given number of data points are not contained in the
X-Y waveform display. The number of data points that define the interpolation zone varies depending on the
display record length.
You can set the interpolation method to one of the options below.
• OFF
Displays the data using dots without interpolation.
• Linear Interpolation (Line)
Linear interpolation is performed between two points.

Setting the Number of Data Points to Use for Waveform Display
(Decimation)
In the X-Y waveform display, the instrument displays the acquired data by removing the data between fixed
intervals. You can set the number of points to use to display waveforms to one of the options listed below.
• When 2k Is Selected
When the record length exceeds 2 kpoint, the DL350 removes data until there are only 2 kpoint and displays
two points on each vertical line. When the record length is less than 2 kpoint, all the points are displayed.
• When 100k Is Selected
When the record length exceeds 100 kpoint, the DL350 removes data until there are only 100 kpoint and
displays 100 points on each vertical line. When the record length is less than 100 kpoint, all the points are
displayed.
During hard disk recording and roll mode display, if there are more than 100 points of data per div, the
maximum and minimum values for specified intervals of data are displayed through linear interpolation.
