WARNING
It is extremely dangerous to generate signals during testing that are on the frequencies that are
in use by local ATC. When operating the test set in ADSB Mode. Please be aware of the local
navigation aid and ATC frequencies. It is the test set operator’s responsibility to make sure all
testing is carried out so there is no effect on other aircraft or ATC resources.
Hints and Tips
When Testing transponders - If power failures are identified it is recommended
to move the test antenna slightly in the horizontal plane and test the transponder
again.
1. Antenna alignment is critical to successful testing of transponders. The ARTS 7000 pulse
antenna is highly directional in both x and y planes and must be positioned in such a way
that the center point of the antenna is pointed as accurately as possible to the aircraft
antenna under test. Failure to get good alignment causes a chance of poor transmissions,
reflections, and multi-path issues.

alignment with an aircraft bottom antenna.
Please see the section on Pulse Antenna Alignment, Reflections, and Multipath.
2. To achieve good ADSB tests, it is critical that they aircraft is in the correct status (i.e. in
“Air mode”). Additionally other systems may need to be operation for the Transponder to
squitter data. For example, GPS position will only be available if the aircraft has valid GPS
signals.
ADSB Out Test Selection

2. From the Test Functions menu select ATC.
3. From the ATC menu select ADSB
4. From the ADSB Menu Select ADSB OUT.
