____________________________________________________
A. General
(1)
This sytem test uses the TIC T-48 or T-49 test set to test the functionality of the ATC system. All data will be shown at the end of the test if the test is successful. If a test has failed, the test sequence will abort and a failed message is displayed. You must do the diversity test and do either the automatic test or the individual tests to completely test the ATC system.
(2)
Operation with the antenna coupler, TAP-115, TAP-118 or TAP 125 used with the applicable test set, is necessary when the test is to do a check of the output power, receiver, sensitivity and radio frequency. For mode S diversity channel isolation check, the TAP 125 is necessary.
(3)
The test is applicable to the left and the right ATC system. Set the transponder select switch on the ATC control panel to the applicable position to do a test of that system.
