2.4 Setting Waveform Acquisition Conditions and Display Conditions
Display Format and Waveform Mapping <Sections 8.1 to 8.4, 8.8 to 8.13>
Display Format
Waveforms can be displayed in divided windows to facilitate the viewing of multi-channel
waveforms and computed waveforms. The screen can be divided into the following
types.
Single (no division), Dual (two divisions), Triad (three divisions), Quad (four divisions),
Octal (eight divisions), Hexadecimal (16 divisions).
Waveform Mapping
You can select the mapping of the input channels to the divided windows from the
following.
Auto: The input channels that are turned ON are assigned in order by the channel
numbers.
Fixed: The input channels are assigned in order by channel number regardless of
whether the channels are ON/OFF.
User: The channels can be assigned arbitrarily to the divided windows regardless of
whether the channels are ON/OFF.
Display Interpolation <Section 8.2>
In areas where less than 1000 points of data exist in the 10 divisions along the time axis
(referred to as interpolation areas), a continuous waveform cannot be displayed because
there is not enough sampled points. In this case, waveform is displayed by interpolating
between data points. You can select the interpolation method from the following:
Linear Interpolation
Linearly interpolates between two dots.
Sine Interpolation
Generates interpolation data using the function sin(x)/x then interpolates between two
dots using the resulting sine curve. Sine interpolation is suitable for observing sine
waves or similar waves.
Interpolation OFF
Displays discrete dots without performing interpolation.
Linear Interpolation
Sine Interpolation
Interpolation OFF
All-Point Display and Decimation Display <Section 8.2>
If the interpolation is OFF, waveforms are displayed using dots. In this setting, up to
2002 points or 100100 points (select either 2 k or 100 k points) of the acquired data are
displayed without using P-P compression (see page 2-12). For example, if the number
of displayed points is set to 100 k and the display record length is 10 kW (the number of
acquired data points is 10010 points), all the points of the waveform are drawn by
aligning 10 points vertically at the same time axis positions. If the number of acquired
data points exceeds 2002 or 100100, the data is decimated down to 2002 or 100100
points (select either 2 k or 100 k points) for displaying the waveform.
