Display Format <For the setup procedure, see section 8.1>
Splitting the Screen
The screen can be split evenly so that input waveforms and computed waveforms can be
easily viewed. The screen can be divided into the following:
Single (no division), Dual (two divisions), Triad (three divisions), Quad (four divisions),
and Hexa (six divisions)*
* Quad (four divisions) and Hexa (six divisions) are not available on the DL1720E.
Waveform Mapping
You can select one of the following for the mapping of the input channels to the divided
windows.
Auto: Waveforms whose input channels are turned ON are assigned in order from the top.
Fixed: Waveforms are assigned in order from the top regardless of whether the input
channels are turned ON or OFF.
User: Channels are assigned in order from the top to an arbitrary number of screen
divisions regardless of whether the input channels are turned ON or OFF.
Display Interpolation <For the setup procedure, see section 8.2>
In interpolation areas where less than 500 points of data exists in ten divisions along the
time axis (or less than 250 points in the zoom display section when waveforms are
zoomed in Main&Z1&Z2), a continuous waveform cannot be displayed because there
are not enough sampled points. In this case, the waveform is displayed by interpolating
between data points. You can select one of the following interpolation methods.
Linear Interpolation
Linearly interpolates between two points.
Sine Interpolation
Generates interpolation data using the function
sin x
x
, then interpolates between two
points using the resulting sine curve. Sine interpolation is suitable for observing sine
waves or similar waves.
Pulse Interpolation
Interpolates between two points in a step pattern.
Interpolation OFF
Displays discrete dots without performing interpolation.
