3d Mode
persistence creates a topographical view of your waveform from a selection of
shadings, textures, and hues. The advantage of the topographical view is that areas of highest
and lowest intensity are shown as peaks and valleys, in addition to color or brightness. The
shape of the peaks (pointed or flat) can reveal further information about the frequency of
occurrences in your waveform. You choose the
Quality
of the 3D display:
Solid
quality can be either color or monochrome. Saturation is set at
50%, with hotter colors indicating highest intensity.
In the monochrome view of solid, the lightest areas indicate highest
intensity, corresponding to the red areas in the color view.
In
shaded
(projected light) quality, the shape of the pulses is
emphasized. This quality is monochrome only.
In
wire frame
quality, lines of equal intensity are used to construct the
persistence map. This display can be either color or
Monochrome
.
In 3d mode,
X Axis Rotation
and
Y Axis Roation
can range 180° from -90° to +90°. In the
examples above, the X-axis is rotated 60° an the Y-axis 15°.
Tip:
To quickly rotate the graph, grab a corner of the persistence map and drag it in the
desired direction.
4. Select the
Saturation
level as a percentage of the maximum population. All populations above
the saturation population are assigned the highest color intensity: that is, they are saturated.
At the same time, all populations below the saturation level are assigned the remaining
intensities. Data populations are dynamically updated as data from new acquisitions is
accumulated. A saturation level of 100% spreads the intensity variation across the entire
distribution; at lower saturation levels the intensity will saturate (become brighter) at the
percentage value specified. Lowering this percentage causes the pixels to be saturated at a
lower population and makes visible those events rarely seen at higher saturation levels.
5. In
Persistence Time
, enter the duration of time (in seconds) after which persistence data is
erased from the display.
6. Choose to superimpose the last waveform over the persistence display by selecting
Show Last
Trace
(not available in 3d mode).
7. To display persistence traces as a continuous line (instead of a series of sample points),
select
Dot Joined
.
Remove Persistence
To turn off persistence and return to the regular trace style, clear
Persistence On
or select an
individual trace's
None
(left-most) persistence mode button.
