Differential Gain vs APL
%
Average picture level defined as the pedestal level
over 4 horizontal lines set to 10%, 50% and 90% of
maximum white level with every 5th line activated
with a standard 5-step staircase signal.
< 5

Regulation of Output Power
%
Variation of peak output power with a change in
average picture level from black to white (0% to
100% APL).
< 3
In-Band Intermodulation Products
