●
Persistence defines how long a data point is displayed in the diagram. Each new data
point remains on the screen for the defined persistence time, or infinitely until the
persistence time is changed or the persistence is cleared.
●
Signal colors or brightness depend on on the cumulative frequency of the values.
By default, values that occur frequently are displayed brighter than rare values. Alter-
natively, the brightness level can be converted to a color range, i.e. the color changes
gradually with increasing cumulative occurance.
It is also possible to invert the brightness display so that rare values are brighter than
frequent values. This setting is useful in combination with persistence to detect rare
values within the waveform.
4.1.1 Configuring the Display
4.1.1.1 Configuring the Diagram Elements
To display the grid or crosshairs
1. Press "DISPLAY > Grid > Lines" to display a grid.
2. Press "DISPLAY > Grid > Reticle" to display crosshairs.
3. Press "DISPLAY > Grid > Off" to remove both the grid and the crosshairs.
To display the trigger event or the channel cursors
The marker of trigger event and the channel cursors are auxiliary cursors. By default,
both auxiliary cursors are displayed. They help to evaluate specific results more easily.
1. Press "DISPLAY > Aux. Cursor > Trigger Event" to display a trigger cursor.
A rhombus marks the point where the trigger event happened.
2. Press "DISPLAY > Aux. Cursor > Channel Cursors" to display a channel cursor.
A dashed line is displayed that marks the ground level of the displayed channel. If a
DC offset is defined, a second auxiliary line is displayed. The distance between those
two lines is the DC offset.
3. Press "DISPLAY > Aux. Cursor > Defaults" to restore the default setting (both cursors
displayed).
4.1.1.2 Configuring the Waveform Display
The waveform display depends on the following criteria:
● Intensities adjust the optimal contrast of the display. See "To configure intensity"
on page 56.
● Persistence defines how long a data point is displayed in the diagram. See "To con-
figure persistence" on page 56.
