Happy viewing. I-1 Technalogix Ltd Section I - Safeguards General Safeguards This section is written as a general guide to keep all 5 fingers on your hand and is intended for those having previous knowledge and experience with these kinds of equipment. It is not intended to contain a complete statement of all safety precautions, which should be observed by personnel using this or other electronic equipment. DOCUMENTATION - Read, retain and follow instructions before operating the equipment. There is a lot of useful information in the manual, and besides, we spent a lot of time writing it! ENVIRONMENT - To reduce the risk of fire or electric shock, do not expose this equipment to rain, moisture, or rye and sodas at the company Christmas party. Refer all servicing to qualified service personnel. SERVICING - Do not attempt to service this equipment yourself as opening or removing covers can result in a warm tingly feeling and will void the warranty. Refer all servicing to qualified service personnel. I-2 Technalogix Ltd Safety and First Aid Personnel engaged in the installation, operation, maintenance, or servicing of electronic equipment are exposed to the hazard of high voltage. It is imperative that all safety regulations and precautions are consistently observed. Knowledge of first aid procedures is recommended. The following information is presented as a reference only. • At all times, avoid placing any part of the body in series between ground and circuit points, whether power is on or off. • Dangerous voltage may be present in equipment even though power is off. Do not open the cabinet. Refer servicing to qualified service personnel. • It is the duty of all personnel to be prepared to give adequate emergency first aid treatment and thereby prevent avoidable loss of life. • There are three principle degrees of burns, recognizable as follows: • a first-degree burn reddens the skin. • a second-degree burn blisters the skin. • a third degree burn chars the flesh and frequently places the victim in a state of shock accompanied by respiratory paralysis. • Respiratory paralysis can cause death by suffocation within seconds. It is imperative that the approved methods of artificial respiration are initiated immediately and continue until the victim’s breathing is normal. • A muscular spasm of unconsciousness may render the victim unable to break free of the electric power. If this is the case, turn the power off immediately. DO NOT TOUCH THE VICTIM OR YOU MAY SHARE THE SAME PREDICAMENT. • If the power cannot be turned off immediately, very carefully loop a dry rope, article of clothing, length of strong cloth or a rolled-up newspaper around the victim and pull the victim free of the power source. Carefully avoid touching the victim or clothing. • Once free of the power source, the victim must be placed in a reclining position and covered with a blanket or newspapers to keep warm. At the first opportunity, enlist help in summoning a doctor. If a doctor cannot be summoned, transport the victim to the doctor or a hospital. Be sure the victim is kept well covered and warm while awaiting professional treatment. I-3 Technalogix Ltd Operating Safeguards It is a known fact that our broadcast transmitters and translators enjoy 50-ohm load impedances. So much so, that it is imperative you maintain 50-ohm impedances throughout your system. In return, your equipment will provide you with maximum power transfer to the antenna and decreased reflected power heading back towards the amplifier pallets, reducing the amount of magic smoke that gets let out of the power amplifier. Before anything is turned on, ensure that there is a 50-ohm path from the output of each stage to the input of the next, all the way to the antenna. In addition to maintaining proper 50-ohm impedances throughout the signal chain, it is also important, whenever possible, to make sure the RF drive going to the input of the power amplifier is removed before turning on or turning off the DC power supply. This is because all of the RF transistors used in the individual amplifier pallets are fabricated with LDMOS (Laterally Diffused Metal Oxide Semiconductor) technology. Nice and linear yes, but they do not like to make any RF power when their supply voltages are not within a specific range. When you first turn your power amplifier on or off, the DC power supply’s output voltage may take a while to stable out to a safe operating voltage. Ten seconds wait before applying the RF drive will ensure no issues arise. Our power amplifiers are designed to reliably generate a specific RF output power. Failing to adhere to overdriven amplifier warnings can decrease the reliability of your system, and frankly, makes our repair department busy and grumpy. If you need to transmit to a little larger coverage, you are better off increasing antenna gain, and more importantly, antenna height above average terrain. On TV and FM broadcast freq…

A Section 4.1.5 - The lower allowed power value should be 95% of authorized power and the upper allowed value should be 105% of authorized power. Procedure: Power was measured using a precision Digital Power Meter through a directional coupler. The Power Meter was calibrated to take into account the loss of the cable used and the coupling factor. Measurement: Rated Output Power = 1000 Watts Exhibit of Output Power: Power Meter 95% 100% 105% Measured Power 950 Watts 1000 Watts 1050 Watts 6 Total Loss (40MHz span) Output Cables+Attenuation+Signal Sampler Total Loss (Wide span) Output Cables+Attenuation+Signal Sampler 7 Signal Sampler Coupling Factor 30dB Attenuation 8 Calculations: For the Output Power a) Total loss including: output cable, 30dB Attenuation and signal sampler = 53.090 dB. b) Measured Output Power = 4.904 mW. 1. Total Loss of the transmission line = Output Cable Loss + Attenuation +Signal Sampler Coupling Factor Total Loss = 53.090 dB 2. Total Loss = 10 log (Power actual /Power measured ) 53.090 dB = 10 log (Power actual /0.004904W) Inv log 5.3090 = Power actual /0.004904W 203704.20 (0.004904W) = Power actual Power actual = Output Power = 998.96W 9 FREQUENCY OFFSET ATSC Standard A/64, Rev. A Section 4.1.6 - The 8-VSB pilot should be 309.441 kHz (± 1 kHz) above the lower edge of the channel assigned to the DTV transmitter. Procedure: The pilot frequency was measured by taking a sample from a directional coupler to a TV Analyzer. The offset in the pilot frequency was displayed on the Analyzer screen automatically. Measurement: Pilot Frequency (Ideal) = 536.3094406 MHz Pilot Frequency (Actual) = 536.3094540 MHz Pilot Frequency Offset = +13.4 Hz Exhibit of Pilot Frequency Offset: 10 FREQUENCY STABILITY ATSC Standard A/64, Rev. A Section 4.1.6 / FCC 47CFR§2.1055 - The output frequency must not exceed +/- 10 KHz from the designated frequency for the pilot. Procedure: The pilot frequency was measured by taking a sample from a directional coupler to a TV Analyzer. Using a “Variac”, the pilot frequency was measured at 85%, 100%, and 115% of the nominal line. In addition, the temperature was varied from 0°C to 50°C and the pilot frequency was measured at 10 degree increments. Measurement: Modulator Line Voltage Volts (V) Percentage (%) Measured Pilot Frequency (MHz) 104 85 536.3095345 120 (nominal) 100 536.3094540 140 115 536.3095986 Temperature (°C) P.A.

The upper and lower shoulder attenuation was displayed on the Analyzer screen automatically. b) The harmonic emissions were measured using the spectrum analyzer’s channel power measurement capabilities. The difference between the total average power of the 6 MHz band and the channel power of each of the harmonics up to 8 GHz (spectrum analyzer’s limitation) including all the corrections* determines if the emissions are within the limits of the 8-VSB Mask. The same measurement applied to spurious emissions but only those of visible amplitude w…
