3 ) Using The Unit With External Sync Signal; (3. 1) H (Horizontal) Phase Adjustment; 4 ) Changing Hd/Vd Input/Output; Synchro. Scan Operation - Toshiba IK-TF7C Instruction Manual

( 3 ) Using the unit with external sync signal

When adjusting H (horizontal) phase refer to the item "7.2 (5) (5.1) Adjusting horizontal phase".

(3. 1) H (horizontal) phase adjustment

Observe the external sync signal and the LVAL signal output
waveform of the unit with a dual trace oscilloscope, and ad-
just H phase so that the H phases match.

7. 4 Synchro. Scan Operation

The shutter speed can be set by the horizontal scanning period (1H) or by the frame.

( 1 ) Setting by 1H

1H/796H to 795H/796H (1H/387H to 386H/387H when partial scanning at 60fps, E.60fps 1H/258H to 257H/
258H when partial scanning at 90fps, E.90fps) stands for the setting by the 1H and the shutter speed can be
set by the 1H (43.05 µs).

( 2 ) Setting by the frame

2FRM to 512FRM stand for the setting (long period exposure) by the frame.
The video signal stored during the frame period set is output as 1 frame video image at a frame interval
specified.
