ATC-601 Mode A/C/S Transponder Ramp Test Set
The ATC-6
601 performs Mode A/C/S transponder tests required by Federal Aviation Regulations
•
Accurate measurement of transponder
transmitting frequency, power and receiver sensitivity
•
AUTO TEST minimizes test time
The ATC-601 provides a comprehensive ‘AUTO TEST’ function
which allows the operator to verify and certify the operation of Mode
S/A/C transponders with little or no intervention once the test has
been commanded.
•
Tests include Flight ID, Tail Number
decode and UELM/DELM data link
Tests may be individually run for diagnostic fault finding purposes
during routine maintenance.
•
Non-volatile storage for two sets of test data
•
Enhanced Surveillance Testing and ADSB/GICB Testing to RTCA-DO260 & ICAO
Annex 10 Vol 3 Chapter 5
The ATC-601 is environmentally packaged to operate in all weather
conditions and be protected against the shock and vibration encountered during ramp use.
•
Operating range of 0 to 300 feet from
the aircraft under test
•
Dump test data to printer via RS-232
•
Built-in self test
•
LCD display with automatic backlight
•
Tripod mountable directional antenna
•
2 hour battery operation
•
FCC Type Acceptance approved
•
Two-year limited warranty
Aeroflex is a leader in the design, manufacture
and marketing of avionics test systems.
The ATC-601 performs the ATC transponder test
required by the revised Federal Aviation
Regulations (91.172 and Part 43, Appendix F as
amended August 18, 1990) for Mode S, A and C
transponders.
OPERATION
Setup Menu
The setup menus are used to program parameters for power and
sensitivity measurements, RS-232 parameters, test data storage,
recall and data dump.
Auto Test
The AUTO TEST screen is selected with the ‘AUTO TEST’ key.
When initiated with the ‘RUN/STOP’ key, this test runs through 23
discrete tests in approximately 30 seconds.
If the required operating modes pass, this completes the ‘Part 43,
Appendix F’ requirements. The detailed results of individual tests
conducted during AUTO TEST are stored in memory and may be
reviewed by using the ‘SELECT’ keys. Once selected, the test may
be initiated by the ‘RUN/STOP’ key and will continue to run until

the ‘RUN/STOP’ key is pressed again.
