When set to Mode 2

For setting the shutter speed using the trigger pulse width

*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

µ

sec (EIA)

Te = Trigger pulse width + 120

µ

sec (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.

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

the normal operation mode, one WEN signal is
output.
