    6-1. Input/Output of HD/VD signal a) Input of External HD/VD signal (Factory Pre-set) Video output of CV-M90(rev.c) in factory pre-set mode can be synchronized with external HD/VD signal (4.0Vp-p ± 2.0V at 75 Ω Ω Ω Ω Ω terminated) .

  • Page 13: A) Random Trigger Mode - 1

    Random Trigger Mode - 1 In Random Trigger Mode-1 (only in Non-interlaced, field accumulation mode), CV-M90(rev.c) starts an exposure (=accumulation of electric charge) at the falling edge of ext. trigger pulse and ends the exposure according to the time set by shutter (7-step fixed shutter speed), and outputs the accumulated signal in one-field (odd-field in EIA and even-field in CCIR).
  • Page 14 Caution on Random Trigger Mode-1 Random trigger mode-1 is effective only at Non-interlaced, field accumulation mode. 1H jitter max. may occur when ext. trigger and Int. HD signals are not synchronized each other. Therefore, It is recommended to make phase- synchronization between ext.

  • Page 15: B) Random Trigger Mode - 2

    In this mode-2, the exposure time of shutter can be controlled within a range of 1/77 ~ 1/10,000sec. by a duration between ext. trigger pulse and ext. VD signal. CV-M90(rev.c) starts the exposure (=accumulation of electric charge) at falling edge of ext.
  • Page 16 Caution on Random Trigger Mode-2 As the Input of ext. VD signal must be given continuously to synchronize with int. VD signal it is not possible to input ext. VD signal ”at random”. Exposure-start may deiay up to 1H max., when the falling edge of ext. trigger pulse is not synchronized with the falling edge of ext.

  • Page 17: C) Long Time Exposure Mode

    In Long Time Exposure mode, the exposure time of shutter can be controlled by a duration of ext. VD signal input. CV-M90(rev.C) starts the exposure (=accumulation of electric charge) after input of ext. VD signal, and ends the exposure after the next input of ext. VD signal. The accumulated video...
