3-5-5. Y/R-Y/B-Y Output Level Adjustment
Measure : SD waveform monitor
Preparation
. The GRB output level adjustment (section 3-5-4) should
be completed.
. Board extension : VDA-57 board (rear side)
. S705 (M-8)/IF-789A/789P → YCD
. S201 (M-8)/IF-789A/789P → OFF
Adjustment Procedure
1. Measuring point : Y/G OUTPUT connector/VDA-57
Measure level A. (about 100 IRE or
700 mV (terminated at 75 Z))
(100% (Y) color bar)
2. S201 (M-8)/IF-789A/789P → ON
3. Y signal level adjustment
Measuring point : Y/G OUTPUT conenctor/VDA-57
Adjusting point : 1RV211 (C-7)/IF-789A/789P
Specifications : B = A (terminated at 75 Z)
(100% color bar)
n
When turning ON S201 (M-8) on the IF-789A/789P
(with SET UP added) and turning off (when SET UP is
not added), the level of A and B should not be
changed.
4. SYNC level adjustment
Measuring point : Y/G OUTPUT connector/VDA-57
Adjusting point : 1RV63 (F-2)/VDA-57
Specifications : C = 40 ±2 IRE
(terminated at 75 Z)
(100% (Y) color bar) (for UC)
C = 300 ±14 mV
(terminated at 75 Z)
(100% (Y) color bar) (for CE)
