When using two or more players, as in an A/B roll editing 
system, it is necessary to synchronize the sync and 
subcarrier (for composite signals) phases of the signals to 
be edited. If they are not synchronized, picture instabilities 
or color break-up may occur at edit points. 

After configuring the editing system, use a vectorscope to 
adjust the sync and subcarrier phases of the recorder and 
players. Subcarrier phase adjustment is necessary when 
using composite signals and Y/C signals.

Press the SCH button on the vectorscope.

The vectorscope switches to SCH mode.

Press the B channel button on the vectorscope.

This displays the black burst signal from the switcher.

Press the EXT button on the vectorscope.

This switches the vectorscope to external 
synchronization mode.

Adjust the phase synchronization control on the 
vectorscope so that the sync and subcarrier phases are 
close to the reference line.

Ensure that the 75 

Ω coaxial cables (A) and (B) (not 

supplied) are of the same length.
