Phase
– Phase adjustment is used in multi-
camera systems when power is supplied from
different sources, thus causing the camera to be
out of phase. This in turn affects auto-switching
by causing rolling of the video during the switch
interval. The vertical phase adjustment allows
the camera’s line lock sync to be adjusted from 0
to 360 degrees with zero line crossing of the ac
power source. To effectively use the phase
adjustment, ensure that all cameras are
powered from the same electrical source and
are wired in a similar fashion. Then, adjust the
phase control on the top of the camera until
there is no rolling video on the monitor when
using the auto-switcher.
•
Iris
– This control adjusts the level of the auto
iris when the A/I lens selection switch is set to
the dc position and a dc lens is mounted on the
camera. The switch should be in the VIDEO
position when an auto-iris video lens is used. If a
video auto-iris lens is used, this adjustment has
no function.
