Mutual Suppression Pulses
Other equipment on board the aircraft may transmit in the same frequency band as the transponder, such
as DME or another transponder. Mutual suppression is a synchronous pulse that is sent to the other
equipment to suppress transmission of a competing transmitter for the duration of the pulse train
transmission. The transponder transmission is suppressed by an external source and other equipment on
board is suppressed by the GTX 32 transponder. This feature is designed to limit mutual interference.

Identification of Installed Equipment
The STC for the installation of a GTX 32 system in an aircraft may contain interfaces into the aircraft's
existing equipment. This GTX 32 installation manual identifies an installation to include:
•
GTX 32 Transponder
•
Transponder Antenna
•
Control and Display unit
•
An Altitude Encoder
The STC includes all the data needed to support the installation of the GTX 32 in all the aircraft identified
on the AML. Although the interface to other equipment is present in the manual, the STC does not
include data for the installation of the Transponder Antenna, Control/Display, or Altitude Encoder. The
installation of the GNS 480 (CNX80) or GDU Multifunction Display, or any other interfaced equipment
is assumed to be covered under the aircraft original TC, another STC, or field approval and is not
modified by or covered under the GTX 32 STC.

The GTX 32 provides the following interface connections via the rear connector:
•
Ten (10) encoding altimeter inputs.
•
Serial altitude output.
•
External IDENT input.
•
External STBY input.
•
