It operates on the secondary radar principle and enables the particular ground stations to locate, identify and track aircraft for the purposes of air traffic control. The transponder can also be used to transmit special information to the air traffic controllers (ATC) at the same time. 2. General description A.The ATC 3401 transponder is constructed as a single module unit designed for installation in the instrument panel or control panel of an aircraft. The dimensions correspond to the ARINC standard for control panels and it is secured in place by means of four DZUS fasteners. B.All controls are located on the front panel of the unit. The unit connector for connecting the aircraft wiring and the antenna socket are fitted on the back of the transponder. C.The control panel contains the electrical modules, processor board and display board. D.The electronic equipment of the transceiver consists of the encoder/power supply module, the receiver/decoder module and the transmitter tube. The receiver/decoder module can be swung out for servicing, thus making all the components of the transponder readily accessible. The transmitter tube is bolted to the side of the unit frame. E.The transponder is ready to operate within 30 seconds of switch on. During this period the display test is performed and the transmitter tube is warmed up and stabilized. F.The following modes are possible with the transponder : (1) Standby mode (SBY) (2)ON mode (mode A) where a code set on the transponder is transmitted back in response to interrogation from a ground station. (3)ALT mode (mode C) where in addition to the facility in mode A the encoded aircraft altitude is also transmitted, provided a coding altimeter is connected to the transponder. (4)Indication of flight level (altitude/100) if a coding altimeter is connected to the transponder. INSTALLATION AND OPERATION ATC 3401 Page 1-1 34-50-07 July 15/97 (5)Additional identification information whereby the ident button of the trans- ponder is pressed on instructions from the air traffic controller. The iden- tification pulse (SPI pulse) transmitted in this case enables immediate identification of the aircraft on the controller’s radar screen, by means of an additional marking on the object display. (6)Test function by pressing the TEST push-button in which all digits flash in the displays and the reply lamp comes on. 3.

Please refer to these documents. The final transmit frequency is determined by a ¼ wavelength cavity resonator (MO5001). The cavity is tuned to the final frequency by means of a screw adjustment that changes the tank cavity capacity. NUMBERTYPE FUNCTION MO5001C0-2080ACavity Oscillator Description of the Circuits and Devices Used for Suppression of Spurious Radiation; For Limiting Modulation: The transmitter output is coupled to the antenna through a 4-section low pass filter. Description of the Circuits and Devices Used for Limiting of Modulation: The transponder uses the standard pulse format as required by ICAO, Annex 10 for both A and C modes of operation. A pulse train from the airborne unit is emitted after being interrogated by the ground unit. Each pulse has a width of 0.45 microseconds spaced 1.45 microseconds apart. Pulse train width between F1 and F2 is 20.3 microseconds. Rise time and fall time of the pulses is typically 0.050 microseconds. 11.
