Figure 4-1: Typical NTSC Waveform display
The Waveform mode vertical graticule scale is in mV or Volts, depending on the
vertical gain setting.
The horizontal graticule scale is calibrated in µs (microseconds) or ns (nanosec-
onds), as appropriate for the horizontal gain setting. The horizontal scale units
indication is centered in the topmost status line, just below the horizontal scale.
A readout of the displayed line number is always shown. If a single line or a
fraction of a line of video is displayed, the readout is located just above the
horizontal graticule scale and somewhere to the right of the vertical scale,
wherever it fits best. If more than one line is displayed, the indicator is found to
the right of sync tip for each line.
