Mode Setting

*1 This is a signal input from outside. The trigger

input frequency must be [Trigger pulse width + 1
field + 2 H frequency] or more. The operation is
not guaranteed for shorter frequencies. If invalid
data is input, normal operation is resumed several
Vs after entering the correct data.

*2 Exposure time (Te)

Te = Trigger pulse width + 97

 µsec (EIA)

Te = Trigger pulse width + 120

 µsec (CCIR)

(The effective trigger pulse width for the external
trigger shutter operation is between 2

 µs and 1/4 s.)

*3 The normal operation state is chosen when the

trigger pulse width is 1/3 s or more. The trigger
falling edge restores the external trigger shutter
operation. In this case, the area between the falling
edge of a trigger pulse and the subsequent 50 ms
period is an external trigger input inhibition area.
There is no guarantee of operation for any triggers
input in this period.

*4 A VD signal is generated after 1 H to 2 H from the

trigger falling edge, then the image is output
synchronized with the VD generation.

*5 When the external trigger shutter mode changes to

the normal operation mode, one WEN signal is
output.
