The ADR-7050 is controlled by individual cockpit displays. Refer to your Aircraft Flight Manual Supplement (AFMS) and the documentation supplied with your cockpit display for detailed instructions. This guide is to be used as an informational supplement. Users should already be familiar with their AFMS and the documentation supplied with the cockpit display. Equipment Description The ADR-7050 (figure 1) contains one communica- tion radio and one navigation radio. The nav portion of the ADR-7050 receives navigational signals and Morse code IDs from VOR stations as well as from localizer and glideslope transmitters. The com portion of the ADR-7050 transmits and receives voice com- munications. Com Radio Features • Communication transmission and receiving capabili- ties at a specified frequency • Voice communication in the range of 118.000– 136.9917 MHz with 25 kHz or 8.33 kHz channel spacing • Frequency monitor function (listens to the standby frequency while monitoring the active frequency) Figure 1. ADR-7050 Remote Navigation/ Communication Tranceiver Model ADR-7050 ADR-7050 Pilot’s Guide  • Adjustable volume control • Intercom function that enables the pilot and copilot to communicate with each other via their headphones without speaker output. This function is only used if the aircraft’s audio panel does not have an intercom function. • Auto squelch function with manual override. The ADR-7050’s auto squelch fea- ture sets a radio noise threshold to silence unwanted noise. The auto squelch level is set using a maintenance computer. Anything below the set threshold is silenced. When squelch is deactivated by the pilot, he will hear noise if no signal is pres- ent on the tuned channel. The ADR-7050 provides indication if the squelch is broken. • Stuck mic condition indication. The ADR-7050 detects a stuck microphone switch if the Push To Talk (PTT) switch is active for more than 35 seconds. If the switch is stuck, the switch becomes unusable. The com radio’s volume, squelch setting, sidetone levels, channel spacing and squelch threshold can be set by the flight system. NOTE All ADR-7050 functions are controlled through various Multi-Func- tion Displays (MFDs). Refer to the AFMS and specific documentation supplied with your cockpit displays for more detailed instructions. Nav Radio Features • VOR receiver operation in the range of 108.00–117.95 MHz in 50 kHz incre- ments • Localizer receiver operation in the range of 108.00–111.95 MHz • Glideslope receiver operation in the range of 329.150–335.00 MHz • Adjustable volume control • Nav ID Filtering. When the filter is on, any voice-over is silenced and only the Morse code identifier is heard. The ADR-7050 decodes the Morse code IDs from the tuned localizer or VOR stations and sends the alphanumeric station IDs to be displayed. VOR, Localizer, & Glideslope Receivers The nav radio also provides VOR, localizer and glide slope signals to the flight sys- tem. When in the VOR mode, you can enter an OmniBearing Select (OBS) setting through the flight system. The VOR receiver determines the appropriate Course Deviation Indicator (CDI) output to send back to the flight system based on the received signal and the OBS input. The VOR receiver also outputs the nav a…

Enable the transmitter in the CW mode and measure the power of the transmitter on the IFR-4000 test set. Record the measured power level. The requirement is for the power to be greater than 16W and less than 55W. Peak Power Output Measurement Measured Data Requirement Power output at 118.00 MHz 17 W 16W< < 55 Watts Power output at 136.975 MHz 17 W 16W < < 55 Watts Rationale and Notes: Part 2.1046 requires a power measurement with a declaration as to the load impedance. Part 87.131 states a power limit of 55W when using A3E. The governing FAA specification (DO- 186A) requires a minimum output power of 16 W. Test 2: part 2.1047 Modulation Characteristics Use the Audio generator to drive the transmitter to 50 % modulation at 1 KHz. Sweep the audio generator and record the audio frequency response of the transmitter. Do this for the 6K00 mode of operation. Audio frequency Response of transmitter -70 -60 -50 -40 -30 -20 -10 0 10 100100010000 Frequency in Hz Modulation Response Normalized to 50% Modulation Use the Audio generator to drive the transmitter to achieve a maximum modulation level. Adjust the audio input frequency to the frequencies listed below and use the spectrum analyzer to verify that the modulation amount does not exceed 100%. Record the amount of modulation out of the transmitter at the indicated audio frequencies. Audio Frequency. Max Modulation Level when overdriving input by 16 dB (Requirement is less than 100%) 100Hz 30% 350 Hz 80% 1000Hz 76% 2500 Hz 73% 3500 Hz 70% 5000Hz 0.6% Rationale and Notes: Part 2.1047 requires a power a curve showing the frequency response of the Transmit modulated signal. Curves are attached for both BW designators Part 87.141 states that the modulation level shall not exceed 100 %. Test 3: part 2.1049 Occupied Bandwidth Set the transmitter to 120.00 MHz. Modulate the transmitter with an audio signal to produce a 50% modulation at 2500Hz audio frequency (each sideband will be -12 dB down). After the 50% modulation is achieved, increase the audio input level by 16 dB (increase audio drive X 6.3). Sweep the audio frequency generator out in frequency until the transmitter is modulating at 20%. The outer frequency where 20% modulation is achieved is one half the occupied bandwidth Occupied Bandwidth Necessary BW Designator Measured Data Requirement 6K00 7.56 KHz 6.0 KHz < < 25 KHz Rationale and Notes: Part 2.1049 requires a measurement that indicates the occupied BW of the modulated signal Part 87.137 indicates that 6K00A3E is an acceptable type of modulation. It also authorizes 25 KHz of BW for the 6K00 emission. Test 4: part 2.1051 Spurious Emissions from Antenna While Transmitting: With the transmitter set to 137.00 MHz key the transmitter such that a non modulated (CW) tone is transmitted. Measure the spectrum from the unit from 9 KHz to 1.4 GHz. Note the highest harmonic and its level in the data sheet. The requirement is that no harmonic shall be greater than -13 dBm. While Receiving: With the unit in receive mode, look at each receive port on the spectrum analyzer. Determine the frequency and power level of the highest emission from each port. The requirement is no greater than -57 dBm Spurious Emissions Measurement Measured Frequency and level of highest emission Requirement 9 kHz – 1400 MHz – during non transmission TX/RCV Port -80 dBm @235 MHz -57 dBm 9 kHz – 1400 MHz – during non transmission/ RCV only port -79 dBm @235 MHz -57 dBm Harmonics from 200 MHz – 1.215 GHz -35 dBm @ 274 MHz (2 nd Harmonic) -61 dBm @ 411 MHz (3 rd Harmonic) All other harmonics less than -70 dBm -13 dBm Rationale and Notes: Part 2.10…

Conducted emissions were measured over the frequency range of 150 kHz to 30 MHz. The EUT was tested to the requirement of RTCA/DO-160E, Section 21, Category L. 9.2LEADS SUBJECT TO TEST P1 +28 Vdc P1 Return P2 Return P2 +28 Vdc P1 Cable P2 Cable CAM COAX NAV COAX 9.3TEST PROCEDURE The general test setup is shown in Figure 9-1. The EUT was operated as described in Section 3 of this test report. All power, signal, and control leads were separated from the ground plane by 5 centimeters. The following test procedure was repeated for all leads subject to testing. A current probe (see Figure 9-2 for current-probe correction factors) was attached around each test lead, in turn. The automated spectrum analyzer was used to measure emissions within the frequency range from 150 kHz to 30 MHz. All signals within the frequency range from 150 kHz to 30 MHz were measured and recorded, including all out-of-spec signals. While the measurement system was scanning through the frequency range, the appropriate current probe factor (impulse bandwidth) was added to the reading, using the equations found in the sample calculation section. The data was then plotted against the appropriate limit. R&B Laboratory Report No.06_1261 Revision Page No.73 of 156 The following data was noted: 1. Receiver/analyzer and current probe used 2.

Emissions were measured over the frequency range of 2 MHz to 6 GHz. The EUT was tested to the requirement of RTCA/DO-160E, Section 21, Category L. 10.2TEST PROCEDURE The general test setup is shown in Figure 10-1. The EUT was operated as described in Section 3 of this test report. A 5-μH LISN was inserted into each dc power lead 1 meter from the EUT and bonded on the ground plane. All power, signal, and control leads were separated from the ground plane by 5 centimeters. A probe was used to determine the area of maximum radiation from the EUT. This part of the unit was oriented closest to the receiving antenna during the test. Radiated emissions were measured at a distance of one meter from the EUT. A variety of antennas was necessary to cover the required frequency range of the test. The following antennas and the corresponding frequency ranges were used to cover the specified frequency range: AntennaFrequency Range Active Rod2 MHz - 30 MHz Biconical30 MHz - 200 MHz Log Periodic200 MHz - 1000 MHz Double Ridged Guide1 GHz - 6 GHz The antenna factors for the above antennas can be found in Figures 10-2 through 10-5. At frequencies above 30 MHz, emissions were measured using both horizontal and vertical antenna polarizations. The Hewlett Packard 8593EM Spectrum Analyzer was used to measure emissions within the frequency range from 2 MHz to 6 GHz. All signals within the frequency range from 2 MHz to 6 GHz were measured and recorded, including all out-of-spec signals.
