XC-E series
ELECTRONIC SHUTTER
External trigger shutter
These modes are used to capture one image (one field) per trigger pulse.
Set DIP switches 6, 7, and 8 on the rear panel to mode 1 or 2. (Refer to the table below.)
When the trigger pulse width is 1/3 sec or more, the output signal is switched to a normal video signal.
There are two modes for timing in which a video signal is obtained.
• Mode 1 (Non-reset mode)
In this mode, a video signal synchronized with a VD signal is output after a trigger pulse is input.
• A video signal is synchronized with the external VD signal when an external HD/VD signal is input.
• A video signal is synchronized with an internal VD signal when no external HD/VD signal is input.
• Mode 2 (Reset mode)
In this mode, an internal video signal is output from a trigger pulse after a certain period of time.
Video sync is always fixed with odd field for XC-ST70 and even field for XC-ST70CE.
*
For more details of each timing chart, refer to pages 16 to 23.
Setting of external trigger shutter speed
