3.15.2.3 Timing Adjustment XtenDD

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
switcher autophasers (41

µ

s). The output signals of the sources must correspond 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 –9 line to +10 lines.
