Using trigger pulse width

Set all DIP switches (1 to 4 on the rear panel) to 0.

You can obtain an arbitrary shutter speed by setting the

trigger pulse width within the range of 2 µ sec to 250

msec.

Mode 1 (Non-reset mode)

Exposure time = Trigger pulse width + 97 µ sec (EIA)

Trigger pulse width + 120 µ sec

(CCIR)

Notes

• The DIP switch 5 position is optional. (The field

setting is recomended.) The field setting can obtain a

sensitivity that is twice that of the frame setting.

• If you input another trigger pulse before the video

signal output for the previous trigger pulse is

completely output, an incorrect video signal will be

output.

• Specifications of trigger pulse

When using a trigger pulse like shown below, set

the TRIG polarity selector switch on the rear panel

to + :

2 µsec – 1/4 sec

1) If you set the trigger pulse with the DIP switches, use the

100 msec to 1/4 sec pulse width.

Mode 2 (Reset mode)

2 – 5.0 V

0 – 0.6 V

When using a trigger pulse like shown below, set

the TRIG polarity selector switch on the rear panel

to – :

2 µsec – 1/4 sec

• Input impedance: 10 kΩ or more.

• The voltage and pulse width used are measured at pin

11 of a 12-pin multi-connector on the rear panel.
