NTSC Vertical Scales
The NTSC graticule is shown in Figure 4-1. The left side of
the graticule is scaledin IRE units and extends from --50to
+120 IRE in 10 IRE increments. A mV scale has been added
to the right sideof the NTSC graticule to facilitate compo-
nent measurements.
Black level setup isdenoted by a dashed line at 7.5 IRE.
There are ±2IRE and±4 IRE markings at the center of the
--40 IRE line to assist in measuring sync a mplitude. This
scale is designedfor use with two line or two field sweep
rates.
The graticules are also marked forK--Factortolerances and
linear-distortionmeasurements. These measurementswill be
describedlater in this section.
