Specifications
R gain, B gain
Adjust VR10 and VR11 so that the white spot on Vector
scope is in the center.
C1 gain
Adjust VR12 so that each color dot on the Vector scope
combines into one spot.
4.3.4 Y LEVEL, SETUP LEVEL
Use Waveform monitor.
Observe the waveform and adjust VR8 to set the white
level to 95 IRE.
Put lens cap on and adjust VR9 so that setup (Pedestal
level) is 5 IRE.
4.3.5 R-Y GAIN, B-Y GAIN, R-Y HUE, B-Y HUE
Use Vector scope.
Adjust VR5 (R-Y gain), VR4 (B-Y gain),
VR2 (R-Y Hue), VR3 (B-Y Hue) to set each vector as
shown below
4.3.6 AUTO WHITE BALANCE
Make sure lens is closed. Probe TP2 and adjust VR18
so that the level is at 5V. Now turn lens to F/16, and
make sure DC level goes down to zero. Optimize VR18
so that the above two conditions are satisfied.
4.3.7 AGC
Switch on to AGC side.
Adjust lens to see if AGC is functioning.
Observe the AGC threshold level and adjust AGC
potentiometer if necessary.
4.3.8 SHUTTER CONTROL AND INTEGRATION
CONTROL
1. WEN: Write enable output
2. SMD2: Select integration mode (Jumper to
GND)
3. SMD1: Select shutter mode (Factory set)
4. SW MODE: Auto shutter pulse width mode
Shutter control
Select SMD1 low (GND) and SMD2 high (open).
This is factory set mode. If external control is required,
