XC-ST30/30CE
PHASE CONDITIONS OF EXTERNAL
SYNCHRONIZATION
External synchronization for each mode
• For normal video/normal shutter
Continuous HD/VD signal (should conform to EIA and CCIR frequencies in the timing shown in the figure below.)
• For Restart Reset (RR)/external trigger shutter
Continuous HD signal. The phase between VD (reset) and HD signals is as specified in the figure below in any
timing.
Phase conditions
The phase relation between external input HD and VD signals should be set as shown below with respect to the
specified center phase.
EXT-VD
ODD

EVEN
(ODD)
EXT-HD
The operation in parentheses refers to XC-ST50CE/ST30CE.
