5.5 TIMING / GENLOCK ALIGNMENT (IN PREPARATION)
When source signals are fed into the switcher, it must be ensured that the time dif-
ference between the sources is not outside the operating range of the internal swit-
cher autophasers (XtenDD = 22
µ
s). The output signals of the sources must corre-
spond to the timing customary in operation. For instance, no EE picture in a VTR,
PB-Ref on CCVS etc.
The switcher’s Genlock Phase can be adjusted to the fed reference signal in the
range of -15 line to + 15 lines.
