GB/T 3789.30-1991 Measurements of the electrical properties of transmitting tubes--Methods of measuring the distortion in the chrominance signal due to the luminance (differential gain and differential phase) (English Version)
This standard specifies the test method for the distortion of the chrominance signal caused by the emission tube due to the difference in the level of the luminance signal. This standard applies to transmitting tubes used in television transmitting equipment.
