10. Set the leveled sine wave generator frequency to 50 kHz and adjust its
amplitude for a 100 IRE (NTSC) or 700 mV (PAL) output as displayed on
the 1710J-Series Waveform Monitor.
11. Set the leveled sine wave generator frequency to 6 MHz.
12. Adjust C195 (CH A Comp) for 100 IRE (NTSC ) or for 700 mV (PAL).
13. Set the leveled sine wave generator frequency to 3.58 MHz (NTSC ) or 4.43
(PAL) and check for 100 IRE or 700 mV
±
2% (2 IRE or 14 mV).
14. If not in specification at 3.58 or 4.43 MHz, repeat steps 5 through 7 (as set
up by steps 1 and 2).
The component to be adjusted is A3C696.
1. Select CH B input.
2. Select 2 LINE sweep.
3. Set the leveled sine wave generator frequency to 6 MHz.
4. Adjust C696 (CH B Comp) to overlay the CH A display with the CH B
display.
5. Set the leveled sine wave generator frequency to 3.58 MHz (NTSC) or 4.43
(PAL) and check for 100 IRE or 700 mV
±
2% (2 IRE or 14 mV).
