1.6.3.8. CLAMP (for ANALOG input)

This adjustment is normally unnecessary. The optimum value is automatically set in automatic input signal scanning.

Used to adjust a clamp pulse position and the width according to the timing of an input signal. Incorrect CLAMP setting makes whole image darkened and uneven horizontal brightness appears on the image. CLAMP is automatically set to the optimum value when you set

CLAMP START=0, CLAMP WIDTH=0. [Procedure]

1.Select CLAMP START in the input memory menu.

2.Adjust the clamp pulse start position.

3.Select CLAMP WIDTH in the input memory menu.

4.Adjust the clamp pulse width.

1.6.3.9. MASK (for ANALOG input in PH50 and XL50)

This adjustment is normally unnecessary. The optimum value is automatically set in automatic input signal scanning.

Used to adjust when the upper or lower part of an image is distorted while 3-line signal (sync on green) or 4-line signal (composite sync) input.

[Procedure]

1.Select MASK START in the input memory menu

2.Set the maximum value that resolves the image distortion.

3.Select MASK END in the input memory menu.

4.Set the minimum value that resolves the image distortion.

1.6.3.10. SYNC SELECT (for ANALOG input)

This adjustment is normally unnecessary. The optimum value is automatically set in automatic input signal scanning.

Used to select sync on green setting. The initial setting is AUTO. Set SOG (sync on green) for 5-line (separate sync) or 4-line (composite sync) input with sync on green signals since this clamp pulse on the green channel cannot be adjusted.

[Procedure]

1.Select SYNC SELECT in the input memory menu.

2.Select AUTO or SOG.

1.6.3.11. CLOCK RANGE (for ANALOG input)

This adjustment is normally unnecessary. The optimum value is automatically selected when H.TOTAL is set.

Used to set the dot clock frequency of an input signal. If a jitter noise still remains even after H.TOTAL and FINE adjustment, fine-tuning of CLOCK RANGE may improve it.

[Procedure]

1.Select CLOCK RANGE in the input memory menu.

2.Adjust the value to eliminate the jitter noise by left/right buttons.
