Connection of Equipment
According to the specification for the input terminal (S VIDEO
input, VIDEO input, or DV input), connect measuring equipment
as shown in Fig. 5-3-1, and make adjustment.
The input terminal is specified in ( ) of the signal column.
Any input terminal can be used unless otherwise specified.
To switch between S VIDEO INPUT and VIDEO INPUT, use the
VIDEO SELECT button on the front panel.
Note 1:
In adjustments specifying for the S VIDEO input to be
used, using the VIDEO input would disable the product
specifications of this unit from being satisfied. Always
use the input signal specified.
Note 2:
If adjustments are used with the VTR with the S video
output terminal as the signal source, the performance of
this unit may be affected by the VTR. Use a pattern gen-
erator with a Y/C separator terminal as much as possible.
