Persistence
The screen captures below illustrate the concept of persistence.
In the first example, the minimum level is being shown. The green
area below the waveform is the lowest level the waveform has
reached.
Waterfall Waterfall is another feature that enables you to see where a
waveform has been in the recent past. It does this by scrolling
the old waveforms up and to the right, creating a three-
dimensional view of how the waveform has changed over
time.
2dB / Div
Scale
This feature provides a close-up view of the waveform by
changing the scale shown on the right side of the display. In
2dB mode, each horizontal line on the display represents a
change of 2dB instead of the usual 5dB.
