Explanation of Functions
Display Interpolation «For procedures, see 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 points.
Sine Interpolation
sin x
x
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
If the interpolation is OFF, waveforms are displayed using dots. In this setting, up to
100100 points (100 kpoints) of the acquired data are displayed without using P-P
compression (page 2-4). For details, see page 2-5.
Graticule «For procedures, see section 8.3.»
You can change the type of graticule that is displayed to suit your needs. For example,
you can show a grid on the screen or show only the frame.
Accumulated Display «For procedures, see section 8.4.»
This mode holds each waveform on the screen for a time that is longer than the update
cycle, so that newer waveforms appear overlapped on older waveforms. If you select
Persist, the waveforms are accumulated.
Accumulated display is useful when you want to observe jitters and temporary turbulence
in waveforms. Accumulated display is also possible on waveforms that are recalled using
the history memory function.
