Figure 6-7. Oscilloscope Display of the WINDOW, H STRIPE or V STRIPE Signal Waveform, White Polarity
NOTE
The window offers a low duty cycle test. A central white area is proportioned to
provide a 25% duty cycle (average picture level). This is surrounded by a uniform
black background over the remainder of the raster. Standard proportions of the
white area are 0.50h (50% of the active portion of horizontal line) and 0.50v (50% of
the active portion of the vertical field).
The sharp transition from black to white and white to black at the edges of the
window in the horizontal dimension provides a convenient tool for analysis of
transient response also.
