In this manual, the term GTX 330 applies to both transponders unless otherwise stated. Information pertaining to the maintenance, alignment, and procurement of replacement parts is found in the GTX 330 Maintenance Manual, P/N 190-00207-05. After installation of the GTX 330, FAA Form 337 must be completed by an appropriately certificated agency to return the aircraft to service. 1.2EQUIPMENT DESCRIPTION The Garmin GTX 330 is a panel mounted Mode S Transponder with the addition of timers, altitude reporting, mode S interrogation and reply, and multiple transmit/receive ARINC 429 and RS232 data ports. The Mode S transponder has the capability to transmit a unique address for every aircraft. The GTX 330 is a radio transmitter and receiver that operates on radar frequencies, receiving ground radar or TCAS interrogations at 1030 MHz and transmitting a coded response of pulses to ground-based radar on a frequency of 1090 MHz. The GTX 330 is equipped with IDENT capability that activates the Special Position Identification (SPI) pulse for 18 seconds. As with other Mode A/Mode C transponders, the GTX 330 replies with any one of 4,096 codes, which differ in the position and number of pulses transmitted. By replying to ground transmissions or TCAS interrogations, the GTX 330 enables ATC to display aircraft identification, altitude and ground speed as well as identification numbers on ATC radar screens or TCAS traffic indicators. The GTX 330 is configured with all key controls. The layout of the front panel keys and displays segregates the transponderís primary functions from the secondary functions. The unit can be configured so the aircraft avionics master bus can turn the unit on. 1.3INTERFACE SUMMARY The GTX 330 provides the following interface connections via the rear connector: • Ten (10) encoding altimeter inputs. • External IDENT input. • External STBY input. • External suppression pulse input. • Switched power output of up to 1.5 amps (for digital altitude encoder power). • Aircraft power input (11 to 33 volts). • Aircraft dimming buss input voltage. • Aircraft master switch turn-on option. Page 1-2GTX 330 Installation Manual Rev. 1190-00207-02 • Serial altitude or GPS groundspeed input. • Serial altitude output. • Mode S with Extended Squitter, Comm A and Comm B protocol. • Temperature, Altitude Hold, Density Altitude and the ability to enter flight ID or tail numbers. • Digitally recorded voice and discrete warning annunciator activated by Altitude Hold when limits are exceeded. • Diversity: GTX 330 is available with or without the Diversity feature. 1.4GTX 330 TECHNICAL SPECIFICATIONS 1.4.1 GTX 330 Electrical Specifications SPECIFICATIONCHARACTERISTIC TSO, JTSO; GTX 330 TSO-C112 CL 2A4 121 010 , JTSO-2C112a.

TX Alignment Procedure Alignment of the GTX330 TX board consists of adjusting five trimmer capacitors for best power consistent with acceptable rise time and fall time. 1.1. Initial Trimmer Cap Settings Before applying power to the unit, preset the trimmer as described below: C124: Turn fully clockwise, then turn counterclockwise 5 turns. C127: Turn fully clockwise, then turn counterclockwise 3 turns. C129: Turn fully clockwise, then turn counterclockwise 4 turns. C131: Turn fully clockwise, then turn counterclockwise 1 turns. C135: Turn fully clockwise, then turn counterclockwise 5 turns. 1.2. TX Alignment Steps 1. Turn on the unit in test mode. 2. Set the SDX2000 or IFR1400 to ATCRBS mode, 50 PRF and interrogate the unit. 3. Adjust C135 for maximum power. The measured power should be greater than 150 watts. 4. Adjust C131 clockwise until pulse power just begins to drop, then turn counterclockwise ½ turn. 5. Adjust C129 for maximum power consistent with minimum rise time. 6. Repeat steps 3, 4, and 5. 7. Adjust the multiturn pot R177 for minimum pulse width. 8. Via the front panel display, select the test page for setting pulse width. 9. Using the CRSR button, select the pulse width field. 10. Set the pulse width to the first setting which gives a pulse width at or below 450 nS. Press the 8 key to decrease pulse width and the 9 key to increase the pulse width. The CRSR button must be pressed to load the new value. 11. Adjust the multiturn pot R177 to increase pulse width and fall time. The desired pulse width is 470 +/- 5 nS. The corresponding fall time should be in the range 80-110 nS. 12. Verify that pulse rise time is less than 85 nS, fall time is greater than 80 nS, and power >160 watts at the end of a 1.5 dB cable.

Equipment and Cable Configuration Test Setup The EUT was arranged in a typical engineering test setup configuration. The EUT was connected to a dc power supply for power and a coaxial cable was connected to the antenna output terminal. The output signal of the EUT was split by a directional coupler and connected to a spectrum analyzer and the IFR test box. This provided a 50-ohm load and response signals to exercise the EUT. On the attenuated output port of the directional coupler a notch filter, attenuation and spectrum analyzer was connected. The notch filter was used at the spectrum analyzer input to attenuate the fundamental frequency centered at 1090 MHz. Refer to Figure 1 for a diagram of the test setup.
