• Acquisition squitter - Acquisition squitter, or short squitter, is the transponder
24 bit identification address. The transmission is sent periodically, regardless
of the presence of interrogations. The purpose of the acquisition squitter is to
enable Mode S ground stations and aircraft equipped with a Traffic Avoidance
System (TAS) to recognize the presence of Mode S-equipped aircraft for selective
interrogation.
Transponder tuning for panel mount transponders like GTX 327 (Mode C) and
GTX330ES is also supported.
