AGL7 module adjustment procedures
12. Select the DAC G
ain (700 mV DC) calibration signal for BLACK 1 through
BLACK 3 as follows:
a. Press the left
(◄)orright(►) arrow button to select BLACK 1,andthen
press the ENTER button.
b. Press the le
ft (◄)orright(►) arrow button to select CAL, and then press
the ENTER button.
c. Press the le
ft (◄)orright(►) arrow button to select DAC Gain (700mV
DC), and then press the ENTER button.
d. Press the B
ACK button twice to return the AGL7 main menu.
e. Repeat parts a through d of this step to select the calibration s ignal for
BLACK 2. B
LACK 3 u ses the previous setting (same as BLACK 2).
13. Locate variable resistor R681 on the AGL7 circuit board. (See Figure 4-1.)
14. Adjust R681 so that the output gain is 700 mV ±1 mV.
15. Move the BNC cable from the BLACK 1 connector to the BLACK 2
connector on the AGL7 Genlock module.
16. Locate variable resistor R481 on the AGL7 circuit board. (See Figure 4-1.)
17. Adjust R481 so that the output gain is 700 mV ±1 mV.
18. Move the BNC cable from the BLACK 2 connector to the BLACK 3
connector on the AGL7 Genlock module.
19. Locate variable resistor R581 on the AGL7 circuit board. (See Figure 4-1.)
20. Adj
ust R581 so that the output gain is 700 mV ±1 mV.
