This setting ØH - horizontal phase
- advances or delays (with respect
to GEN LOCK input) the equip-
ment sync generator so that the
camera channel has the same
phase as the other video sources
at the video mixer input.
This setting ØSc (continuous set-
ting and 0/
Π switching) phase-
shifts (with respect to the GEN
LOCK input) the equipment sub-
carrier (in PAL or NTSC only) so
that the camera chain has the
same phase and sub-carrier as
other video sources at the video
mixer input.
This indicator light indicates that
the equipment sync generator (in
the channel control unit) is slaved
to the external reference signal ap-
plied to the back of the channel
control unit (GEN LOCK IN).
This red indicator light indicates
that the horizontal phase setting
and the sub-carrier phase setting
(in PAL or NTSC) are offset. This
light should be off.
For NTSC standard width adjuste-
ment of vertical blanking (V.BLK)
and horizontal blanking (H.BLK).
This setting varies the level of the
sub-carrier on the encoded out-
puts, on the rear of the channel
control unit, so that the amplitude
of the sub-carrier of the encoded
signal is correct at the mixer input.
ØSc/H adjusts the phase between
the sub-carrier and the horizontal
sync signal. If the equipment is
not servo controlled by an external
reference signal (no video on GEN
LOCK input on the back of the
Channel Control Unit).
