3. Menu Operation DD35 Production Switcher
3 – 178 Operating Instructions – Rev. 16 / 10.2001
3.16.2.4 Timing Adjustment Seraph HD
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. 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 – 12 lines to + 12 lines.
