Frequency Response vs. Brightness:
+0.75 dB or better. Measured using a 20% p.p. swept video modulation
on a pedestal at 10%, 50% and 90% APL (all percentages relative to a
blanking to white excursion).

50%, and 90% of maximum white level, with a standard 5-step chromi-
nance-modulated staircase inserted every fifth line.
Differential Phase:
+1° or better. Measured with the same 5-step staircase signal as in Dif-
ferential Gain.
Incidental Carrier Phase Modulation (ICPM):
+1.5° or better. Carrier phase variation from reference white to sync tip,
referenced to 0 at blanking, and measured with the same 5-step stair-
case signal as in Differential Gain.
Luminance Non-linearity:
1.0 dB or better. Measured with a 5-step staircase signal, Test Signal #3
CCIR Rec. 421-3.
