a) - Nominal CVBS input signal
b) - Nominal settings for contrast, WPA and peaking
c) - Black- and blue-stretch switched-off
d) - Gain of output stage such that no clipping occurs
e) - Beam current limiting not active
f) The tolerance on these values is about
Y = +1.4 V
These signal amplitudes are based on a colour bar
signal with 75% saturation.
Y = +1.0 V
These signal amplitudes are based on a colour bar
signal with 100% saturation.
