T-47N
Multi-Function Test Set
Datasheet DESCRIPTION
The T-47N Test Set provides unsurpassed reliability and
ruggedness from over 45 years of experience and proven
results with U.S. and foreign militaries. The Test Set
capabilities allow test and analysis of the following systems:
Transponders (Modes 1, 2, 3A, C, S, and 4 IFF), TACAN
(Tactical Air Navigation), DME (Distance Measuring
Equipment), Interrogator (Modes 1, 2, 3A, C, and 4), and
TCAS (Traffic Alert and Collision Avoidance Systems).
Code of the Day (MODE 4) memory permits full Interrogator
and Transponder tests in actual environments, ensuring
compliance.
New Feature*
The T-47N provides test capability for Mode S Elementary
and Enhanced Surveillance. The T-47N can receive and
display information contained in Mode S DF 17 Extended
Squitter (ADS-B).

Accurate displayed results provide meaningful troubleshooting information
The T-47N Test Set performs the following transponder tests based on the capabilities of the Unit-Under-Test:
- Mode 4A/4B - Verifies valid Mode 4A/4B bit and tests to verify valid and invalid properties
- Mode 1 and 2 - Verifies Modes 1 (4 digits) and 2 code and reply efficiency
- MC - Mode C decoded altitude and reply efficiency
- M3A - Verifies 3A reply code, IDENT/EMERG capabilities and reply efficiency
- MA and MC ALL CALL - Mode S Address and reply efficiency
- MA and MC Only
- Mode S Surveillance ID (DF5) – Mode S Address, flight status (Air, Ground, Alert, SPI) and reply efficiency
- Mode S Surveillance Altitude (DF4) – Mode S altitude, flight status, reply efficiency, and Mode S/Mode C altitude compare
- Mode S Surveillance Short (DF0) – Mode S address in octal and hex, decoded tail number, flight status, and reply efficiency
- Mode S Comm Identification (UF5/DF21) – Flight ID Number, flight status and reply efficiency
- Mode S Comm Altitude (UF4/DF20) – Mode S altitude, flight status, altitude compare, and reply efficiency
- Mode S Comm C – decoded tail number, flight status, and reply efficiency
- Undesired replies (UF11) – Checks for no reply to incorrect Mode S interrogation address
- Squitter – Pass/Fail indication of correct squitter period
- Max True Airspeed – Decodes transponder programmable maximum airspeed setting
- Power, Receiver, Sensitivity and Frequency – Displays measured power in dB and watts, frequency, and sensitivity. Pass/Fail indication
- Data and framing pulse measurements are monitored and displayed if out of tolerance.
- SLS (Side Lobe Suppression Test)
- Mode S Enhanced Surveillance parameters including Selected Altitude (BDS4); Roll Angle, True Track Angle, Ground Speed, Track
Angle Rate, and True Airspeed (BDS5); Magnetic Heading, Indicated Airspeed, Mach #, Barometric Altitude Rate, and Inertial Vertical
Velocity (BDS6)
- Receives and decodes 1090 MHz ADS-B data including squitter type (airborne position, surface position, aircraft ident/category, and
airborne velocity), lat/long, N/S velocity, E/W velocity, Flight I.D., Mode S address, altitude (GNSS or barometric), and air speed
