(1) The color temperature conversion filter (LB165) is mounted in front of lens.
(2) Indication of vector scope is observed in the grey scale standard record state, and
an adjustment is made so that the luminous dots are located in the following
positions:
R-Y 0 ± 5% (burst ratio)
B-Y 0 ± 5% (burst ratio)
(1) Set the unit to the normal operation mode (write the data "
"0000").
(2) Video output is observed with the oscilloscope in the grey scale standard record
state, the data of address "0002" is rewritten, and the luminance signal level is
adjusted white to 714 ± 10mVp-p.
