HF Transceiver ATP

All relevant receiver and transmitter data are checked in the tests. The ATP is performed if no
adequate BITE fault message is present, or after repair of faults, to verify operation before instal-
lation of the Transceiver on an aircraft. The procedure for peforming the ATP is:
A. Install the HF Transceiver into XCVR Test Tray; ensure that connectors are fully engaged.
B. Turn ON power to the GSE PC.
C. Invoke MS Windows by typing win at the DOS prompt.
D. From Program Manager, double-click on the HFDR icon.
E. Activate the RUN menu and choose START.
F. Follow the instructions that appear on the monitor.
(1) The first dialog to appear is the HFDR ATP CONFIGURATION box. The operator must
type in the Transceiver Part Number, Serial Number, Mod Status, and other optional in-
formation, in the appropriate fields, using the mouse to position the cursor at each field.
When complete, click OK. This information is used in the test log that is being created by
the test software.
(2) During the test, dialog boxes appear, giving instructions for operator action. Follow the
instructions, using the mouse to activate the YES, NO, OK, PAUSE, or ABORT buttons,
as required.
(3) Some dialog boxes require operator actions to observe measurements or to perform con-
nections in the test setup, or to type a measurement in the dialog box field.
(4) A small dialog box is present throughout the test, with the status (PASS or FAIL) of the
current test being run (Task XX, Test XX), and with buttons for PAUSE and ABORT test.
(5) If the Task 12 test failed, perform the tests of step (6).
(6) Task 12: Receive Voice Mode SSB and AM Tests
If the 1kHz tone reading from the audio output for both of these tests fails the 10 ± 1dBm
test, R124 on EMC Filter, A7, can be adjusted to bring the reading within specification.
(7) The test is a PASS if the test result at the end of the test is PASSED.
(8) At the end of the test sequence, the test report data is in memory. Specify a log file (ad-
ditional to the default file previously described):
X:\ATEASY\LOG\HFDR.L00
This log file is stored, by default, in the LOG subdirectory in the ATEasy directory. Wheth-
er a log file is specified as described or not, the test report may be printed from memory
(if a printer is connected), or may be transferred to another PC that can read and print
test files. At the operators discretion, the path, file name, and extension may be changed.
