XC-E series TIMING CHART OF EXTERNAL TRIGGER SHUTTER - MODE 2 (RESET MODE) For setting the shutter speed using TRG width *1 Trigger External trigger shutter operation 1 *2 Exposure time Te *3 Normal operation *3 Trigger Video out 1 WEN *4 1H to 2H 250H (XC-ES50/ES30, XC-EI50/EI30) 293H (XC-ES50CE/ES30CE, XC-EI50CE/EI30CE) 250H (XC-ES50/ES30, XC-EI50/EI30) 293H (XC-ES50CE/ES30CE, XC-EI50CE/EI30CE) Mode transition state External input inhibition area External trigger (50 ms) shutter operation 2 *2 Exposure time Te 2 *4 1H to 2H 250H (XC-ES50/ES30, XC-EI50/EI30) 293H (XC-ES50CE/ES30CE, XC-EI50CE/EI30CE) *1: This is a signal input from the outside. The trigger interval should be trigger pulse width + 1 field + 2H period or more. The trigger interval shorter than described above cannot be ensured. If a trigger pulse is not input under the prescribed conditions, the normal operation is ensured several V after a change in input operation under the prescribed conditions. *2: Exposure time Te Te = Trigger width + 97 µs (XC-ES50/ES30, XC-EI50/EI30), Te = Trigger width + 120 µs (XC-ES50CE/ES30CE, XC-EI50CE/EI30CE) (The trigger width should be between 2 µs and 1/4 s) *3: The normal operation state is engaged when the high period exceeds 1/3 sec. After that, the external trigger shutter operation is engaged when the trigger pulse goes "low". In this case, the area between the falling edge of a trigger pulse and the subsequent 50 ms period is an external input inhibition area. During the trigger inhibit period, an input trigger may be missed. *4: A VD signal is generated 1H to 2H after a trigger pulse falls, and an image is output in synchronization with the VD signal. *5: When the external trigger shutter mode changes into the normal operation mode, a WEN signal is output. 28
