Specifications subject to change without notice.
Difference between ideal and actual color-bar subcarrier amplitudes.
Difference between ideal and actual color-bar subcarrier phase.
Current consumption is larger in standard termination mode. Current values shown for 50% average picture level. Larger current consumption possible for other levels.
