This fast viewing mode provides brightness-graded intensity with a decay
time similar to the action of phosphor on an analog screen.
WaveStream mode operates at up to 80 GS/s with an update rate of up to
several thousand waveforms/second for better capture of higher frequency
abnormal events.
Adjusting Trace Intensity
The I NTENSITY knob adjusts the brightness of your trace.
The intensity value is shown in the bottom-right corner of the screen.
PLEASE NOTE THE FOLLOWING:
Pushing the Intensity knob changes the Persistence status in the following
ways.

OFF - When the button hasn't been pushed, it may be turned to
control the trace Intensity control value.

Analog Persistence - When the button is pushed once, the
waveform resembles a trace on a phosphor oscilloscope. Turning the
knob affects persistence with a blended form of Intensity and
Saturation. As the knob is turned clockwise, the Intensity value
increases while the Saturation value decreases. The opposite occurs
when the button is turned counter clockwise.

Color Persistence - The button behaves the same way as Analog.
However, the grid display shows a color waveform where red
indicates most frequent occurrences while blue denotes the less
frequent.
