Graticules are configured by selecting the Video Input Format along with the
appropriate Waveform Setup scale adjustment (Units, %, or Volts). The scales can also
change when ZOOM is pressed.
Figure 3-7 to Figure 3-9 illustrates some waveform graticules with the critical
amplitude limits for the video formats that can be displayed by the TVM. The critical
amplitude limits are indicated on the screen by special dashed lines.
NOTE: When in VAR mode for all waveform scales, the graticule scale and numeric identifiers
will not be shown. Only the graticule lines will be displayed.
