4. ADJUSTMENTS
Each control is clearly labeled for its function. Each control may be adjusted over a wide range.
Each control may be switched “in” or “out” by using the toggle switch located below the control.
The “out” position sets that function to unity gain (as set within the VTR). The “in” position
enables the associated control.
SetUp
Adjust to eliminate any deviation
Video Gain
Adjust to 100 IRE.
Chroma Gain
Adjust so that the specified level is obtained.
Hue
Adjust so that the vector waveform meets the VTR specifications.
a.
H PHASE AND SUBCARRIER ADJUSTMENTS
These controls are inset screwdriver adjustments. These adjustments are best made
using a waveform/vectorscope and good video alignment practice by trained personnel
only. Consult the VTR operator/s or service manual for the correct procedure.
SC Fine and H Phase are “greenie” adjustment pots.
b. S/C
COARSE
Monitor your vector scope and adjust the SC Coarse switch until you are “in the
ballpark,” then adjust the SC fine (slotted screwdriver adjustment) until you have
adjusted within the unit’s specifications.
0 = coarse 1 & 2 open
1 = coarse 1 to ground
