UTX5KW THEORY OF OPERATION Introduction The UTX5KW Television Transmitter is a TV transmitter capable of providing 5 kW of visual RF power and 500 watts of aural power at the output of the transmitter RF combiner. The transmitter is comprised of a precision modulator and upconverter, driver amplifier, 10 way power splitter, 10 solid state RF power amplifiers operating in parallel, a 10 way power combiner, 9 DC power supplies, RF filter to eliminate spurious products and harmonics, cooling system, AC voltage distribution system, control and monitoring system for the human interface, and all necessary hardware to assemble the transmitter into the transmission facility. The transmitter system is housed in two 19 inch racks. System Operation RF SIGNAL GENERATION Video and audio are fed to the high quality TV modulator/upconverter where the high quality TV visual and aural signals are produced. The upconverter converts the modulated TV signal to its desired channel and eliminates the image frequency product. The solid state driver amplifier accepts the combined visual and aural on-channel RF signal from the upconverter and amplifies the signal with minimum distortion. The signal is fed to a 10 way splitter that distributes an in-phase and equal amplitude signal to each of the 10 power amplifiers. Each power amplifiers accepts the RF signal and is capable of producing a 600 peak of sync NTSC TV waveform. The 10 way combiner accepts all 10 RF signals and combines the signals to one common output connector. The output signal from the combiner feeds a directional coupler. The output from the directional coupler passes through a bandpass filter that reduces all intermodulation products and harmonics to an acceptable level consistent with FCC rules. POWER SUPPLY SYSTEM The incoming main three phase AC power passes through a circuit breaker control panel that distributes the power to various assemblies throughout the transmitter. From the circuit breaker panel, separate single phase AC lines are fed to the modulator/upconverter, driver, control and monitoring system, and air cooling system, as well as auxiliary outlets for the transmitter. The UTX5KW utilizes 9 power supplies. Input AC voltage is fed to each of the DC power supplies via one power supply frame designed to house all of the power supplies. Each one of the DC power supplies converts the AC voltage to approximately 31 volts DC. Its voltage is held constant independent of modulated RF waveform type and overall load. All of the DC outputs from the power supplies are connected in parallel. The power supplies share the load current required by the amplifier group. The entire load current required by the power amplifiers can be provided by eight power supplies so the ninth power supply is redundant. The parallel connection and smart circuitry of the power supplies allows all power supplies to share the load. This combination will also allow one power supply to fail and the transmitter can still operate at full power. SOLID STATE POWER AMPLIFIER Each solid state power amplifier (PA) consists of 2 stages of amplification using LDMOS technology. The power gain of each power amplifier is approximately 26 dB. Within each power amplifier, the first stage serves as a low distortion linear amplifier that increases the power of the combined visual and aural signal roughly 13 dB. This signal is routed to 4 parallel configured final amplifiers. The driver and final amplifier transistors receive DC voltage from the power supply frame elsewhere in the rack via connections on the rear of the amplifier. VSWR and over-temperature protection is provided in order that the transistors are not damaged from high reflected power operating conditions. The heatsink temperature is monitored and whenever it exceeds a pre-determined temperature, a front panel LED indicator is illuminated and the power amplifier module shuts off. Integral fans provide direct cooling air to the amplifier heatsinks to ensure that the heat is removed efficiently from the PA modules. When the temperature decreases back below the threshold, the power amplifier automatically re-enables to the On state. Because the PA unit is broadband, it requires no tuning or adjustments. POWER SUPPLY The power supply architecture is a very efficient DC switching power supply unit. Each power supply is hot-pluggable and is inserted and removed from the front of the transmitter. The unit accepts voltage from a 50 or 60 Hz source. The output voltage is tightly regulated in order to eliminate any amplitude modulation on the output RF signal. Current limit protection is built in to the power supply should it accidentally encounter a very high current demand. Each power supply is cooled by internal fans. RF SPLITTER AND COMBINER The RF splitter is an assembly that separates the RF signal into equal amplitude and in-phase signals for each port. The RF combiner reverses the process and combines all amplifier outputs together. Each group of input cable, power amplifier, and output cable is matched for the same transmission phase angle and amplitude to be present at the RF combiner input RF FILTER The RF filter is a multiple section bandpass filter designed to pass signals in the designated channel and reject all others. Connections for the RF input and output are made through 50 ohm connectors. The filter is tuned to a specific TV channel. CONTROL AND MONITORING SYSTEM The control and monitoring system of the transmitter provides the following functions: Forward Visual, forward Aural, and combined reflected power output level monitoring Status lights for all power amplifier modules Metering for all power amplifier currents RF sample port for monitoring the forward signal using separate test equipment Power Amplifier enable/disable switch AIR COOLING SYSTEM An exhaust fan on the top of the cabinet provides cooling for the system. Cool air is drawn through the front of the transmitter by highly reliable fans in the inβ¦

TEST REPORT PINEAPPLE TECHNOLOGY INC. UTX5KW TV TRANSMITTER TECHNICAL REPORT INTRODUCTION The following information is provided to support the technical performance of the Pineapple Technology UTX5KW TV Transmitter. The information is supplied for broadcast TV service according to applicable portions of Part 73 and 74. 1. Power Output Measurements as indicated by FCC Rule Part 2.1046. 2. Frequency Measurements as identified by FCC Rule Part 2.1055. 3. Visual Frequency response measurements of the transmitter to be within the window specified by FCC Rule Part 74.750. 4. Occupied BW of aural signal specified by FCC Rule Part 2.1079. 5. Aural frequency response as identified by FCC Rule Part 73.687 6. Measurement of conducted harmonics and spurs +/- 3 MHz outside of channel as specified by FCC Rule Part 74.750 and Part 2 Rule 2.1051. 7. Measurement of cabinet radiation of spurs and harmonics as specified in FCC Rule 2.1053 and 2.1057. 8. Measurements of voltage and current to final amp stage as outlined in FCC Rule 2.1033. Measurements were conducted at transmitter output visual power output levels of 4700 watts peak of sync and 1340 watts peak of sync and constitute the range of power for which type certification is sought. The corresponding aural power levels are 470 watts and 134 watts. The test equipment used for the measurements on the next few pages is listed at the back of this exhibit. All test equipment was calibrated prior to the use of the equipment by the supplier of the test equipment. RF POWER OUTPUT The equipment was configured as below shown in Figure 1. The loss through the RF output cable and directional coupler and attenuator was calibrated at the frequency of 577 MHz. The TSG-90 video generator was configured to produce a signal with 0 IRE video and sync. The audio generator and aural carrier were not energized. The visual portion of the transmitter was energized and the power was increased to the desired output power. The power was read on the Bird Calorimeter and a reference level was established on the HP8595E Spectrum Analyzer. The TV demodulator and VM-700 were used to verify that sync compression was not causing distortion of the measurement. The aural carrier was energized and its output level was then raised to meet the precise 10 dB Visual/aural power ratio as observed on the spectrum analyzer. Pictures were also taken of demodulated video of the horizontal sync, and 2 fields of video to verify no signal distortions were present over the 1340 watt to 4.70 kwatt power level range where certification is being sought. POWER OUTPUT Calorimeter reading at high power. Calorimeter reading at low power. Peak of sync power = 2.80 x 1.68 Peak of sync power = 0.80 x 1.68 = 4.70 kwatts = 1.34 kwatts Tektronix TSG-90 Video Generator Tektronix 1410 Video Generator HP 200CD Audio Oscillator Tektronix VM700T HP 54601 Oscilloscope UTX5KW Bird Calorimeter MSI TV Demodulator Agilent 8593E Spectrum A nal y zer HP 8903B Modulation A nal y zer TEST EQUIPMENT CONFIGURATION 40 dB coupler A udio Video Video Quadrature Video Dashed line indicates onl y one instrument connected at a time.

TWO HORIZONTAL LINES AND TWO FIELDS SHOWING CORRECT MODULATION DEPTH FOR REFERENCE WHITE AND SYNC LEVELS AT 1.34 KW Power Output = 1.34 kwatts Power Output = 1.34 kwatts As can be seen from the above photographs there is negligible distortion of the waveforms. FREQUENCY STABILITY MEASUREMENTS Frequency stability versus temperature and line voltage were measured in a controlled environment. For these tests the exciter RF output was fed to a frequency counter that has better than a 1ppm accuracy. The test equipment configuration is shown below. The variac was adjusted for nominal voltage and the frequency was recorded. Then the variac was adjusted to 85% and 115% of the nominal voltage and the frequency was recorded at each voltage level. The results are tabulated below. LINE VOLTAGE (Volts) Visual Frequency (MHz) Aural Frequency (MHz) 100 (85%) 537.249909 541.749918 121 (nominal) 537.249910 541.749917 140 (115%) 537.249909 541.749917 For the temperature stability measurements the exciter was placed inside a Tenney temperature chamber equipped with a MicroTenn II temperature controller. The exciter frequency was measured on the frequency counter. The temperature in the chamber was changed to each of the points identified in the table below. The chamber followed a prescribed rate of 10 minutes to change the frequency and then the temperature was allowed to stabilize at the temperature for 10-15 minutes. When the temperature had stabilized, the exciter visual and aural frequencies were recorded, and then the temperature was advanced to the next measurement point. The temperature was cycled cold first and then returned to room temperature and then cycled hot.

Exciter Frequency Counter Variac AC Input AC OutputRF Output Exciter Frequency Counter Temperature Chamber RF Output FREQUENCY RESPONSE MEASUREMENTS The test equipment configuration of Figure 1 was used with the TSG-90 supplying the video input waveform. For this case, the aural carrier was not energized. A (Sin X)/X input video waveform was used. The output spectrums are displayed on the pictures below. Spectrums for both high power and low power conditions are displayed to confirm that the radiated envelope meets the requirements as outline in Part 74 Rule 750. POWER OUTPUT =4.70 kwatts POWER OUTPUT =1.34 kwatts The scale used for the above pictures is 5 dB per division. The abnormal portion of the output waveform observed in the middle of the passband is the effect of the field rate information. The video field rate sync obscures some of the measurement near the visual carrier but there is still enough of the waveform present to confirm that the radiated spectrum falls within the 4 dB window as specified in FCC Rule 74.750.
OCCUPIED BANDWIDTH MEASUREMENTS The test equipment was configured as in Figure 1. The aural carrier was energized and increased in power until the desired Visual to Aural power ratio of 10 dB was met. The visual input waveform used was a β0β IRE video input level from the TSG-90 and the aural input signal was a 15 kHz sine wave taken from the HP 200CD audio generator. The aural deviation was increased until the desired level (85% of 25 kHz = 21.25 kHz) was indicated on the HP8903B modulation analyzer. The output spectrum was observed on the HP 8593 spectrum analyzer noting the requirements as identified in FCC Rule Part 2.1079. As can be observed, the output spectrum meets these requirements. OCCUPIED BANDWIDTHβPOWER OUTPUT = 4.70 kWatts (Scan width = 200 kHz) OCCUPIED BANDWIDTHβPOWER OUTPUT = 1.34 kWatts (Scan width = 200 kHz) AURAL FREQUENCY RESPONSE The equipment configuration of Figure 1 was used. The visual and aural carriers were energized and the aural carrier was modulated by the HP200CD audio frequency generator. A reference was set at 400 Hz and the audio generator level was adjusted to achieve 25 kHz deviation at each frequency using the calibrated audio output (in mvolt/kHz) from the TV demodulator. The following table of audio response was obtained by dividing the output audio level by the reference level at 400 Hz. This table is displayed on the graph shown on the next page. The input termination to the UTX5KW was fixed at 600 ohms. The oscilloscope was used to compare the input voltage with the output demodulated voltage from the TV Demod (and also compared to the 8903B) to determine the response level. The results are tabulated below and plotted on the next page meeting the prescribed limits as shown on the graph.

CONDUCTED SPURIOUS AND HARMONICS The following photographs indicate the spurious performance (> +/- 3 MHz) from the designated TV channel. As can be seen from the photos (one taken at high power and the other taken at low power), the spurious levels are below 60 dB relative to the peak of sync of the visual carrier. The scan width is 30 MHz on the left hand picture and 20 MHz on the right hand picture. POWER OUTPUT = 4.7 kWatts POWER OUTPUT = 1.34 kWatts CONDUCTED HARMONIC OUTPUTS The following data indicate the harmonic performance of the UTX5KW. Only the 2 nd harmonics were visible. The following table displays the actual value of the harmonic that takes into account the coupling factor of the directional coupler and loss of the cable used for the measurement. There was no value recorded when the instrument measured value was <-75dB relative to the visual peak of sync value as this was below the noise floor of the spectrum analyzer with the bandwidth used. Photographs of the spectrum containing the second harmonic are shown below. The pictures indicate that the harmonic levels are below 60 dB. HARMONIC LEVELS VERSUS FREQUENCY AT 4.7 KW FREQUENCY OF HARMONIC (MHz) AMPLITUDE (Relative to visual Peak Sync at fundamental frequency (dB)) 1114 (2 nd harmonic) -68 1671 (3 rd harmonic) -75 2228 (4 th harmonic) <-75 2783 (5 th harmonic) <-75 3342 (6 th harmonic) <-75 3899 (7 th harmonic) <-75 4456 (8 th harmonic) <-75 5013 (9 th harmonic) <-75 5570 (10 th harmonic) <-75 POWER OUTPUT = 4.7 kWatts POWER OUTPUT = 1.34 kWatts Both Photographs are centered at the 2 nd Harmonic because only those harmonics were visible. The fundamental frequency visual peak of sync reference value is located at the top of the screen on these photographs. The values indicate a maximum harmonic level of -68 dB when corrected for coupling and cable loss at 4.7 kW. HARMONIC LEVELS VERSUS FREQUENCY AT 1.34 KW FREQUENCY OF HARMONIC (MHz) AMPLITUDE (Relative to visual Peak Sync at fundamental frequency (dB)) 1114 (2 nd harmonic) -69 1671 (3 rd harmonic) -75 2228 (4 th harmonic) <-75 2783 (5 th harmonic) <-75 3342 (6 th harmonic) <-75 3899 (7 th harmonic) <-75 4456 (8 th harmonic) <-75 5013 (9 th harmonic) <-75 5570 (10 th harmonic) <-75 CABINET RADIATION The transmitter and test equipment were configured as shown below including the angles of measurement with respect to the transmitter cabinet. The photo on the subsequent page also shows the physical set-up of the test equipment and equipment under test. The transmitter was operated at 4.7 kW peak sync power with a 10 dB visual/aural ratio with the video input signal being a sync signal and 50 IRE βset-upβ level. The free space path loss, cable loss, and antenna gain characteristics were obtained at the fundamental frequency and at each of the harmonics of the visual carrier frequency in order to accurately assess the level of the signal radiated from the cabinet. The cabinet was measured at a distance of 30 feet in 4 different physical rotation angles: 0, 90, 180, and 270 degrees (0 degrees being the front of the cabinet). All spectral components above -80 dB referenced to peak sync power radiated from the cabinet were recorded. Their orientation that included the highest values are tabulated in the table on the next page following the photos.
