Table 4–2: DC Restorer
Name Description
DC Restorer Clamp Time Backporch (J500 on/off)
n
Frequency Response at 60 Hz Slow — 20% or less
Fast — 90% or greater
Attenuation of 60 Hz on input signal (J399 Fast/Slow)
n
Blanking Level Shift with 10% to 90% APL
Change APL changes from 50% to either 10% or 90% will cause blanking level shift of 1 IRE
unit [7.14 mV] or less
n
Blanking Level Shift Due to Presence or
Absence of Burst 1 IRE unit [7.14 mV] or less shift from no color burst to presence of color burst
