External Sync Frequency Range.41; Using The Unit With External Sync Signal.41; (3.1) H (Horizontal) Phase Adjustment.41; (3.2) Sc (Sub Carrier) Phase Afjustment.41 - Toshiba IK-TU51CU Instruction Manual

(2) External svnc frequency range
(External sync with VBS, SYNC)
For NTSC standard frequency : Within ±50ppm
(External sync with HD, VD)
For EIA standard frequency : Within ±1% (at horizontal sync frequency)
(3) Using the unit with external svnc signal
Adjust H (horizontal) phase and SC (sub carrier) phase if necessary to match the output of multiple cameras.
When adjusting H (horizontal) phase and SC (sub carrier) phase, refer to the item "7.2 (6) SYNC".
(3. 1) H (horizontal) phase adjustment
Observe the external sync signal and the video signal output
waveform of the unit with a dual trace oscilloscope, and adjust
H phase so that the H phases match.

(3. 2) SC (Sub carrier) phase adjustment
When using the unit with external sync, the sub carrier signal phase of the video output signal of the unit can
be adjusted. Perform a coarse adjustment for 0o and 180o in SC 0/180 and then perform a fine adjustment
in SC PHASE. Using a vector scope for the phase adjustment will provide more accuracy.
