CV-M300
Cautions in the Pulse Width Control Mode.
1. Pulse width control mode is effective only in non-interlaced field accumulation mode.
2. The exposure start may be delayed up to 1H max., when the falling edge of ext. trigger pulse is not
synchronized with the falling edge of ext. HD signal. To avoid this 1H jitter and delay, the falling edge
of the ext. trigger pulse should be synchronized within 4.4 usec. to the HD pulse. It can be the ext. HD
in or the Internal HD out.
See cautions in Edge Pre-select Mode page 7.
3. The voltage level of the ext. trigger has to be 4.0 Vp-p ± 2.0 V. The duration of the negative going
trigger signal has to be longer than 1H = 64 µsec. and shorter than 60 msec. The input signal is AC
coupled.
