( 3 ) PW SNR (Pulse width trigger SYNC-NON RESET)
The trigger input to CC1 of the DIGITAL terminal develops 1 frame images.

*2: | Exposure time = Trigger pulse width + 6 ∝s |
| |
| (Valid trigger pulse width is 2 ∝s or greater for external trigger shutter operation.) |
*3: Video is output at the falling edge of the internal VD following completion of the exposure period. The video and FVAL/LVAL/DVAL have a paired relationship.
Note:
When the next trigger is input before completion of the output of the video corresponding to the trig- ger, there will be an effect on the video.
