Environmental Conditions Temperature Humidity Pressure (ºC) (%) (mbar) 24-25.3 24.1-32.2 956-962 Model: NGT-9000D+ and NGT-9000RD+ Description: Mode-S transponder Additional Information: NGT-9000D+ is the panel mount unit with S/N LXE13068 and NGT-9000RD+ is the remote unit with S/N LXE13369. The panel mount and remote mount units use identical internal circuit cards with the exception of the touch screen display. Both Conducted and radiated testing is done on panel mount unit and only radiated testing is repeated on remote mount unit. NGT-9000 is a mode S transponder that provides 1090 MHz automatic dependent surveillance-broadcast information and also supports an optional active traffic (TAS/TCAS1) 1030 MHz function.

Carrier Output Power (Conducted) Engineer: Poona Saber Test Date: 7/9/2019 Test Procedure The Equipment Under Test (EUT) was connected through a directional coupler directly to a spectrum analyzer with the RBW > OBW and the VBW set to 3 X RBW which set the RBW greater than the transmit signal ensuring there was no signal suppression while measuring a modulated signal. The peak readings were taken for TCAS and Transponder systems for both ATCRBS(C) and S modes and the result was then compared to the limit. The Average RMS power is the peak power multiplied by duty cycle of the Transponder and TCAS system. Section 87.131, for Radio navigation equipment Note 7 specifies “Frequency, emission and maximum power will be determined by appropriate standards during the certification process. TCAS output power is controlled by the requirements of FAA TSO-C118a AND TSO-C147 similarly to the output spectrum. In addition the Transponder output power is controlled by the requirements of FAA TSO C112d. Test Setup EUT Directional Spectrum Coupler Analyzer p1960015_FCC_Part 87_Rev 5.0 Page 8 of 21

Radiated Spurious Radiation Engineer: Poona Saber Test Date: 7/12/19 Test Procedure The EUT was setup and tested in anechoic chamber. Both top and bottom antenna ports are connected into the simulator with matched load. The EUT is placed on non-conductive platform at a height of 0.8 meters above the ground plane of the semi-anechoic chambers for emissions below 1 GHz and at a height of 1.5 meter for emissions above 1 GHz. The test distance from measurement antenna is 3 meters and EUT was rotated 360 degrees and the receive antenna raised and lowered to find the maximum emissions from 30MHz to the 10th harmonic of the fundamental. The EUT was set to the maximum power level allowed and RBW is set to 100 KHz for measurements below 1Ghz and 1Mhz for measurements above 1GHz. Radiated measurements are done on both Panel mount and Remote mount units.

Modulation Details 1 ATCRBS Interrogations Interrogations are sent out on an intentionally jittered 1+/- 0.2 second interval in increasing power levels according to the schedules shown in Table 1. By transmitting the weakest signals first, only the closest aircraft will reply. The interrogations progress in a roughly circular pattern weighted toward the front of the aircraft since that is the area from which the greatest closing speeds originate. In areas of high density, the sequence is halted when the computer has reached a limit defined by a complex set of three inequalities. In this manner, interference to other TCAS equipped aircraft in the area is minimized since the strongest interrogations are the first to be dropped.

Pulse S1 will appear in all steps except the initial step on each antenna direction and at a level two or three dB below the level of P1, etc. according to the schedules shown in Figure 1 through Figure 4. The steps occur at intervals of two milliseconds until the entire program is complete. The program length depends upon the individual aircraft installation. Options are available from using either an omni-directional bottom antenna or a directional bottom antenna. The top antenna is always directional. S1 = -2 microseconds P1 = 0 microseconds P3 = 21 microseconds 2 ATCRBS Replies ATCRBS replies are pulse amplitude modulated signals (PAM), and are formed in response to Mode A or Mode C interrogations. Mode A replies consist of a 4096 code which is an identifier and an optional SPI pulse. The Transmitter CCA transmits ATCRBS reply pulse waveforms as shown in Figure 3.

1. Mode S Reply a. The Mode S preamble consists of four 0.5 ± 0.05 microsecond pulses. b. The second, third and fourth pulses are spaced 1.0, 3.5, and 4.5 microseconds respectively from the first transmitted pulse. c. The block of reply data pulses begins 8.0 microseconds after the first transmitted pulse and is either 56 or 112 one microsecond intervals depending on the type of Mode S Reply. d. A pulse with a width of 0.5 ± 0.05 microseconds is transmitted either in the first (data bit “1”) or in the second half (data bit “0”) of each interval. Also, if a pulse transmitted in the second half of one interval is followed by a pulse transmitted in the first half of the next interval, the two pulses merge. Once the merging occurs, a 1.0 ± 0.05 microsecond pulse is transmitted 2. Mode S Reply Pulse Shape a. The pulse rise and decay time are as specified in the table below. Table 5: Mode S Reply Pulses (in microseconds) Rise Time Decay Time Pulse Designator Min. Max. Min. Max Mode S Reply Pulses 0.05 0.1 0.05 0.2 3. Mode S Reply Pulse Spacing Tolerance a. Mode S Reply pulses start at a defined multiple of 0.5 microseconds from the first transmitted pulse. b. The pulse position tolerance must be ± 0.05 microseconds, measured from the first pulse of the reply. p1960015_FCC_Part 87_Rev 5.0 Page 20 of 21
