BLACK PULSE TEST CHART

REFLECTANCE

The test chart is used to measure low and intermediate frequency response (streaking) and

flare in video systems.

The white background has a density of ~ 0.15 . The black rectangle has a width equal to

25% of picture width (approx. 0.05 MHz). In addition the chart shows a narrow black pulse,

width equal to 1% picture width (approx. 1.25 MHz). The density of the black picture area is

D > 1.9 (remission < 0,1%).
