Vertical Linearity Adjustment
Input signal:
Monoscope signal
Measuring equipment: SHIBASOKU TP20A1
Adjustment point:
SFR501
Adjustment method:
Adjust the vertical linearity so that the number of vertical position scales at the topmost end and at the
bottommost end are of equal amount using SFR501. The vertical linearity adjustment and the vertical
picture position adjustment must be performed together alternately. Repeat the vertical picture position
adjustment and the vertical linearity adjustment each other a few times so that the number of scales in the
topmost end and the bottommost end are of equal amount when the center line is positioned at the center
mark.
Simplified adjustment procedure
If a monoscope signal is not available, connect the playback video signal of VTR that plays back TTV-N6T (test tape), to the
external video input connector and perform the horizontal picture position adjustment in the same manner as shown above.
Alternately, connect the cross-hatch output signal of the pattern generator to the external video input connector. Adjust the
vertical linearity so that the number of vertical position scales at the topmost end and at the bottommost end are of equal
amount using SFR501.
Vertical Picture Size Adjustment
Input signal:
Monoscope signal
Measuring equipment: SHIBASOKU TP20A1
Adjustment point:
Adjustment menu PAGE 1 "3. V. SIZE"
Adjustment method:
Adjust the vertical picture size so that the vertical position scales at the topmost end and at the bottommost
end of a monoscope picture are 4.5±0.5 scales using the VOLUME UP/DOWN key of the jig remote
controller.
Simplified adjustment procedure
If a monoscope signal is not available, connect the playback video signal of VTR that plays back TTV-N6T (test tape), to the
external video input connector and perform the horizontal picture size adjustment in the same manner as shown above.
Alternately, connect the cross-hatch output signal of the pattern generator to the external video input connector. Adjust the
vertical picture size so that the pattern of the cross-hatch screen becomes complete square using the VOLUME UP/DOWN key
of the jig remote controller.
OSD Position Adjustment
Input signal:
No input signal is required
Adjustment point:
Adjustment menu PAGE 1-4
Adjustment method:
Adjust the OSD position so that the crossing (+) mark on both sides of the OSD are positioned in the same
distance from the both ends of screen, using the VOLUME UP/DOWN key of the jig remote controller.
