level on the waveform. The DC Restore selections are Off and On (slow).
Off = DC offset appears.
On Slow = DC offset removed.
Waveform Intensity
The Waveform Intensity is used to raise or lower the brightness of the displayed waveform.
The range of intensity is 25% to 200%. NORMAL is the default intensity setting.
Waveform Contrast
Waveform Contrast is used to adjust the overall difference between the lightest and darkest
colors of the waveform. The range of contrast is 25% to 200%. NORMAL (100%) is the default
