AGL7 module adjustment procedures
17. Change the hori
zontal fine timing of the BLACK 1 output from –10.0 ns to
+10.0 ns and verify that the CH2 signal moves at least 18.5 ns.
18. If the CH2 sign
al moves less than 18.5 ns, turn R473 its center position and
then perform the following steps:
a. Change the C
H1 probe connection from TP504 to TP502.
b. Set the horizontal fine timing of BLACK 1 output to 0.00 ns.
c. Adjust R472 so that the CH2 signal is de layed by 8 ±0.5 ns from the
CH1 signal.
d. Change the horizontal fine timing of the BLACK 1 output from –10.0 ns
to +10.0 ns and verify that the CH2 signal moves at least 18.5 ns.
If the CH2 signal still moves less than 18.5 ns, turn R473 completely
clockwise and then repeat parts a through d.
19. Change the CH2 probe connection from TP410 to TP420.
20. Adjust R474 so that the CH2 signal is delayed by 8 ±0.5 ns from the
CH1 signal.
21. Change the CH1 probe connection from TP504 to TP502.
22. Change the horizontal fine timing of the BLACK 2 output from –10.0 ns to
+10.0 ns and verify that the CH2 signal moves at least 18.5 ns.
23. If the CH2 signal moves less than 18.5 ns, turn R475 its center position and
then perform the following steps:
a. Change the CH1 probe connection from TP502 to TP504.
b. Set the horizontal fine timing of BLACK 2 output to 0.00 ns.
c. Ad
just R474 so that the CH2 signal is delayed by 8 ±0.5 ns from the
CH1 signal.
