Description
0
Ygain% 100
The shaft encoder can be used to adjust the luminance gain.
1
Yoff+mV 3
The shaft encoder can be used to adjust the luminance offset (black level).
2
CGain% 100
The shaft encoder can be used to adjust both the U and V chrominance gains.
3
Ugain% 100
The shaft encoder can be used to adjust the U chrominance gain.
4
Vgain% 100
The shaft encoder can be used to adjust the V chrominance gain.
Note:
The displayed number varies as the shaft encoder is rotated to give an indication of the
setting relative to the factory default
Select position 0 (Ygain) with the SEL control to allow the shaft encoder to adjust the
luminance gain from 0 to 200%.
Select position 1 (Yoff) with the SEL control to allow the shaft encoder to adjust the
black level from –30 to +385mV.
Select position 2 (Cgain) with the SEL control to allow the shaft encoder to adjust the
overall chrominance gain from 0 to 200%.
Select position 3 (Ugain) with the SEL control to allow the shaft encoder to adjust the U
chrominance gain from 0 to 200%.
Select position 4 (Vgain) with the SEL control to allow the shaft encoder to adjust the V
chrominance gain from 0 to 200%.
Adjusting signal timing
Use rotary switch (SEL) positions 5, 6, 8 and 9 together with the shaft encoder to change
the following:
Output timing relative to the active reference
Chroma phase relative to burst (10 bit mode only)
Input video timing (10 bit mode only)
The horizontal and vertical timing adjustments relative to the active reference are separate
for 625 and 525 line operation. The settings for composite and Y/C (S-video) phase are
also stored separately, as are the phase settings for PAL and NTSC. This gives a total of
four separate phase adjustments, two each in PAL and NTSC.
All these parameters are automatically maintained when the unit is powered off and
restored when the unit is powered back on.
