Adjustment Procedure
1710J-Series Waveform Monitors
7–15
12. Set the sine wave generator Frequency to 4.00 MHz.
13. Re-adjust C777 for minimum chrominance.
The components to adjust are A3R683 and A3C683 for NTSC instruments, or
A3R680 and A3C778 for PAL instruments.
1. Use a 75
W
coaxial cable to connect the television test signal generator color
bar signal to the 1710J-Series Waveform Monitor CH A input.
2. Set the television test signal generator for Full Field and turn off Luminance
(Y) and Setup (NTSC). Set color bar amplitude to 75%.
3. Set the 1710J-Series Waveform Monitor to CH A, CHRM FILTER, 1 LINE
sweep, and sweep MAG off.
4. Adjust R683 (NTSC Chroma Filter Gain) or R680 (PAL Chroma Filter
Gain) so that the amplitude of the largest color packet is 100 IRE or 700 mV,
depending on the color standard employed.
5. Adjust C683 (3.58 NTSC) or C778 (PAL) for the squarest envelope
(minimum burst envelope decay time). It may be necessary to readjust C783
(NTSC) or C784 (PAL) for maximum amplitude.
6. It may be necessary to perform steps 4 and 5 several times before reaching
the optimum setting for both Gain and Chroma Filter Compensation.
7. Move A3J500 (DC Restore) jumper to the 2-3 (On) position.
