TEST REPORT PINEAPPLE TECHNOLOGY INC. LTX100U TV TRANSMITTER TECHNICAL REPORT INTRODUCTION The following information is provided to support the technical performance of the Pineapple Technology LTX100U TV Transmitter. The information is supplied for broadcast TV service according to applicable portions of FCC rules contained in Part 2, Part 73, and 74. The test report is comprised of tests made upon channel 47. However, since there are no frequency dependent parts within the transmitter (the final transmitter filter is tunable per channel and ordered on a per channel basis) the test report constitutes an accurate and representative sample of the transmitter performance anywhere in the approved frequency range of 470-608 MHz and from 614-806 MHz. 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 the transmitter visual power output level of 100 watts peak of sync (W ps ) for which type certification is sought. The corresponding aural power level is 5 watts. Measurements were taken on a unit with visual carrier frequency of 669.24 MHz and an aural carrier frequency of 673.74 MHz. (This transmitter is operating on CH 47 with a negative 10 kHz offset). The test equipment used for the measurements on the next few pages is listed at the end of the test report. 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 shown in Figure 1. The loss through the directional coupler was calibrated at the operating frequency (671.0 MHz). The TSG-90 video generator was configured to produce a signal with 0 IRE video and sync. The aural carrier was not energized. The visual portion of the transmitter was energized to the desired output power (0.1 kWps). The power was read on the HP-435B Power Meter. The video demodulator and 1750 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 13 dB visual/aural power ratio as observed on the spectrum analyzer. Pictures were also taken of demodulated video with two (2) lines of a modulated stair step (or reference white level) , and two (2) fields of video to verify no signal distortions were present at the 0.1 kW power level where certification is being sought. HIGH POWER OUTPUT HP 435B Power Meter reading -3.75 dBm Loss in directional coupler 51.5 dB Sum 47.75 dBm = 59.5 W Avg Peak of sync power = 1.68 times average power under the following conditions: 0 IRE (Black) picture No aural carrier 40 IRE of sync Proper sync to video ratio (40/100) and depth of modulation, this is shown by the two line modulated stair step display. 59.5 W Avg. X 1.68 = 99.96 W peak of sync (Within 0.1 dB of 100 W) The aural carrier was set 13 dB lower. 100 W ps = 50 dBm minus 13 dB equals 37 dBm = 5 W Aural Power DC voltage and current to final amplifier stage is: 7.6 Amps at 32 VDC measured with black level input.

FREQUENCY STABILITY MEASUREMENTS (NTSC) The exciter used for this transmitter is the same model of exciter used in the type certified UTX-2K Ultra transmitter with FCC ID PW2UTX2KULTRA. Therefore, the frequency stability measurements from that transmitter exciter are repeated here for inclusion and completeness. 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 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. For this test, the -10 kHz offset was used. The results are tabulated below. LINE VOLTAGE (Volts) Visual Frequency (MHz) Aural Frequency (MHz) 100 (85%) 507.239979 511.739882 121 (nominal) 507.239979 511.739882 140 (115%) 507.239979 511.739882 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 to change the temperature 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 measured first at room temperature and then raised to +50 °C, allowed to stabilize for 15 minutes and then cycled to each colder temperature measurement point. Temperature °C Time Visual Frequency (MHz) Aural Frequency (MHz) 25 1:30 507.250,000 511.749,913 50 2:50 507.249,793 511.750,038 40 3:10 507.249,781 511.749,818 30 3:20 507.249,955 511.749,877 20 3:30 507.249,885 511.749,770 10 3:45 507.249,577 511.749,407 0 4:00 507.249,434 511.749,343 -10 4:10 507.249,523 511.749,397 -20 4:20 507.249,567 511.749,816 -30 4:30 507.249,613 511.750,255 From the measurements above, it is apparent that the FCC rules in Part 2.1055 and in Part 74 are met.

1 Tested By: Ed Wood Date: 14 Feb 07 VISUAL TRANSMITTER FREQUENCY RESPONSE MEASUREMENTS The test equipment configuration of Figure 1 was used with the 1410 video generator supplying the video input waveform. For this test, the aural carrier was left energized. A variable frequency sine wave sweep of 90 IRE Peak-to-Peak amplitude from 100 kHz to 6.0 MHz with pedestal set at 52.5 IRE input video waveform was used. The modulation output was increased until the maximum excursion reached reference white and 10 IRE as shown in the photos in Fig. 4 and Fig. 5 below. The RF sideband output level was measured for the sidebands below and above the visual carrier. The frequency response was displayed on the HP Spectrum Analyzer. The spectrum plot, showing markers at the Visual Carrier and at 4.75 MHz ( 51 dB down from Visual Carrier ), is displayed in Fig. 6 to confirm that the radiated envelope meets the requirements as outlined in FCC Part 74 Rule 750. FREQUENCY RESPONSE INPUT WAVEFORMS Fig. 4 - Two (2) Horizontal Lines 2 Fig. 5 – Two (2) Fields The photograph of the spectrum analyzer display below demonstrates compliance with FCC 74.750. Fig. 6

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 ratio of 13dB (5%) was met. The visual waveform used was a 0 IRE video input level from the TSG-90 and the aural input signal was a 15kHz sine wave taken from the HP339A Distortion Measurement Set. The aural deviation was increased until the desired level (85% of 25kHz =21.25 kHz) was indicated by the HP339A Distortion Measurement Set monitoring the calibrated deviation output (25mV/kHz) of the MSI 320 Precision Video Demodulator. The output spectrum was observed on the HP Spectrum Analyzer noting the requirements as identified in FCC Rule Part 2.1079. As can be observed, the output waveform meets these requirements. OCCUPIED BANDWIDTH- POWER OUTPUT =0.1 kW ps (Scan width = 200kHz) Fig. 7

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 HP 339A Distortion Measurement Set. The visual input waveform used was a “0” IRE video input level from the TSG-90. A reference level was set at 100Hz and the audio generator level was adjusted to achieve 25kHz deviation at each modulating frequency using the calibrated audio output (25mV/kHz into 75 ohms) from the MSI 320 TV demodulator. The following table of audio response was obtained by dividing the output audio level by the input level. This table is plotted on the graph shown below. The adjustment of -1 dB was used to center the plot within the graph.

1 Tested By Ed Wood Date: 14 Feb 07 CONDUCTED SPURIOUS AND HARMONICS The following photographs indicate the spurious performance (> +/- 3 MHz) from the designated TV channel. As can be seen from the photo taken at 100 W, the spurious levels are below 60 dB relative to the peak of sync of the visual carrier. The top of the display indicates the true peak of sync value when the vertical interval portion of the picture is present. The photo in Fig. 8 shows the desired 13 dB visual to aural power ratio. Fig. 8 CONDUCTED HARMONIC OUTPUTS The following data indicates the harmonic performance of the LTX100U. Only the 2 nd harmonic was 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 measured value was <-75 dB 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 well below 60 dB compared to the top of the display which represents visual sync peak power. 2 HARMONIC LEVELS VERSUS FREQUENCY AT Pout=100 W FREQUENCY OF HARMONIC (MHz) AMPLITUDE (Relative to visual Peak Sync at fundamental frequency (dB)) 1338.48 (2 nd harmonic) -63 dB 2007.12 (3 rd harmonic) ** dB 2676.96 (4 th harmonic) ** dB 3346.2 (5 th harmonic) ** dB 4015.44 (6 th harmonic) ** dB 4684.68 (7 th harmonic) ** dB 5353.42 (8 th harmonic) ** dB 6023.16 (9 th harmonic) ** dB 6692.4 (10 th harmonic) ** dB ** Note: Amplitude at or below the noise floor of -75dBc Photo of 2 nd Harmonic Spectrum Fig. 9 The photograph in Fig. 9 is centered at the 2 nd Harmonic because only that harmonic was possibly visible. The fundamental frequency visual peak of sync reference value is located at the top of the screen on this photograph. The values indicate a maximum harmonic level of -63 dB when corrected for coupling and cable loss. 3 Fig. 10 The photograph in Fig. 10 is centered at the 3 rd Harmonic showing the noise floor at around -75 dBc when corrected for coupling and cable loss. The fundamental frequency visual peak of sync reference value is located at the top of the screen on this photograph.

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 operating at 100W peak sync power with a 13dB visual/aural ratio with the video input signal being a sync signal and 50 IRE “set-up” 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. Radiation from 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. The values are tabulated in the table on the next page following the photo. PHYSICAL CABINET RADIATION TEST CONFIGURATION This photograph shows the actual laboratory environment in which the cabinet radiation tests were conducted. The log periodic antenna, cable and spectrum analyzer are shown in the foreground and the LTX100U is shown in the background. The transmitter was rotated 90 degrees for each of the measurement orientations. As calculated from the spreadsheet data on the following page, the worst case measurement was -64 dBm at the second harmonic (The photo above shows this particular measurement). The measurement tables for the remaining views of the transmitter are shown on the following pages. LTX100U Xmtr Pineapple Technology Inc.
