To Set Color Display
Color temperature adopts the change of waveforms’ color to reflect the change of the
waveforms’ appearing probability. The greater the probability that the waveform appears, the
warmer the color is; the smaller the waveform appears, the colder the color is.
The picture below shows the change of color from cold to warm. Press the Display button
on the front panel, and then press the Color softkey and set the option to On to turn on
the color temperature function. You can compare the waveform’s color with the picture
below to just the probability that the waveform appears.

To Set and Clear Persistence
With persistence, the oscilloscope updates the display with new acquisitions, but does
not immediately erase the results of previous acquisitions. All previous acquisitions are
displayed with reduced intensity. New acquisitions are shown in their normal color with
normal intensity.
Do the following steps to set and clear persistence:
1. Press the Display/Persist button on the front panel to enter the DISPLAY function
menu.
2. Press the Persist softkey; then turn the Universal Knob to select the desires option.
Off —turn of persistence.
Variable persistence time (1 second, 5 seconds, 10 seconds, 30 seconds ) — select
different persistence time, the results of previous acquisitions are erased after a
certain amount of time
Infinite —select “Infinite” Results of previous acquisitions are never erased. Use
infinite persistence to measure noise and jitter, to see the worst- case extremes of
varying waveforms, to look for timing violations, or to capture events that occur
infrequently.
