Trace Label Display (Trace Label)
You can display waveform labels next to the displayed waveforms. If the waveform display is narrow because of
the display format settings, labels may not be displayed.
• ON: Displays labels
• OFF: Does not display labels
Level Indicator
A level indicator that shows the levels of the waveforms whose displays are turned on appears on the right side
of the waveform display area. It shows the current levels of the sampled data.
Interpolation Method (Dot Connect)
When the number of data points is within the interpolation zone of the T-Y waveform display,
*
the DL850E/
DL850EV displays 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 10
div along the time axis. The number of data points that define the interpolation zone varies depending on the
display record length and zoom ratio.
You can set the interpolation method to one of the options below.
• OFF
Displays the data using dots without interpolation.
• Sine Interpolation (Sine)
Interpolates a sine curve between two points using the (sinx)/x function. This method is suitable for the
observation of sine waves.
• Linear Interpolation (Line)
Linearly interpolates between two points.
• Pulse Interpolation (Pulse)
Interpolates between two points in a staircase pattern.
Outside of the Interpolation Zone
If the interpolation method is set to Sine, Line, or Pulse, the dots are connected vertically.
If the number of data points is 2002 or greater, the DL850E/DL850EV determines the P-P compression values (the
maximum and minimum sampled-data values in a given interval), and displays vertical lines (rasters) connecting
each pair of maximum and minimum P-P compression values.
