4.4.1 CABLE ATT ADJ
INITIALIZE -> 2: ECHO -> 2
The level of video signals inputted into the processor unit differ depending on the
antenna cable length. To adjust the loss correction for it, two types of adjustment
methods are available (AUTO or MANUAL). You can use the both of them. After the
AUTO adjustment, you can make a correction by the MANUAL adjustment.
The adjusted data is saved on the SPU board. Based on this data, “CABLE ATT ADJ” is
executed on the IF board of the TR unit.
When AUTO is executed, a message “CABLE ATT ADJ” is displayed. It takes about 5
minutes to complete the adjustment. Proper noise levels are automatically adjusted and
the adjusted data is saved on the SPU board.
In the MANUAL adjustment, set the 24 NM range, the long pulse, Gain to “80”, STC to
“0”, FTC/EAV/ES/ to OFF and IR to “2”, and then make adjustment so as that the grass
noise slightly appears.
