To Set Color Display; To Set And Clear Persistence - Teledyne T3DSO1000A Series User Manual

Set Display Color Temperature
Color temperature adopts the change of waveforms' color to reflect the change of the
waveforms' appearance. The more frequently that the waveform appears, the warmer
the color is; the less frequent 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 understand the frequency 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 off persistence.
●
Variable persistence time (1 second, 5 seconds, 10 seconds, 30 seconds ) —
select appropriate persistence time, the results of previous acquisitions are
erased after the persistence 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.
