6. Set the oscilloscope to the horizontal rate and
expand the horizontal sync portion on the oscillo-
scope.
7. Move the cursor to H PHASE.
8. Adjust the horizontal phase by pressing L or M.
The adjustable range is 0 - 2.0 µs.
9. Move the cursor to SC COARSE.
10. Press L or M to match the chroma phase of the
camera's video signal, when observed at the output
of the Special Effect Generator (SEG) or Switcher,
as closely as possible to the color of the original
scene. (SC COARSE adjustment can be increment-
ed in steps of 90 degrees (4 steps) by pressing L
or M.)
Note: After the fourth step, the adjustment returns
to the first step.
1 (1 - - 4): 0 degrees
2 (1 - - 4): 90 degrees
3 (1 - - 4): 180 degrees
4 (1 - - 4): 270 degrees
11. Move the cursor to SC FINE.
12. Press L or M to match the color (hue) of the
camera's video signal, when observed at the output
of the Special Effect Generator (SEG) or Switcher,
as closely as possible to the color of the original
scene.
The SC FINE adjustment has a range of 90 degrees
of color shift.
Notes:
• When the "I" cursor reaches the "+" end, it
jumps back to "–". At the same time, SC
COARSE is incremented by one step to enable
a continuous adjustment. The reverse takes
place when the "I" cursor reaches the "–" end.
• When L or M is kept pressed for a second
or more, the "I" cursor moves faster.
• For more accurate adjustment, supply both the
original camera video output signal and the
effect output video signal (program output
video signal) of the special effects generator
(SEG) to a vectorscope and compare the chro-
ma phase of both signals.
• To reset SC COARSE and SC FINE to the val-
ues preset at the factory, press L and M
simultaneously.
