Display Interpolation

Page 8-2.
≡
This feature selects the type of interpolation applied in areas where there are less than 500
sample points per 10 time-axis divisions. (These areas are referred to as interpolation areas.)
Three settings are available.
Line interpolation
Interpolates between two dots using a straight line.
Sine interpolation
Generates interpolation data using the function sin(x)/x then interpolates between two dots
using resulting sine curve. Sine interpolation is suitable for observation of sine waves.
No interpolation
Displays measurements as discrete dots, without interpolation.
Note
• If interpolation is set OFF, you can use any of the following compression methods to display data in the
non-interpolation areas.
P-P:
Selects use of P-P compression.
Decim: Displays data at intervals.
All:
Displays all values.
• If interpolation is set to Sine or Line, the unit will always use P-P compression for data display in non-
interpolation areas.
Accumulated Waveform Display
≡
Page 8-5.
≡
This mode holds each waveform on the screen for a time that is longer than the update cycle, so
that multiple waveforms are overlapped.
The following two modes are available.
• Persist : Overlaps the display of waveforms using one color.
• Color : Overlaps the display of waveforms using 8 colors which signify the frequency of
occurrence of the data values.
This function is useful when you want to observe jitters and temporary turbulence in
waveforms.
