Cathode drive level (15 steps; 3.5 V/step)
Note
1.
The given values are valid for the following conditions:
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
±
3 V.
