The synthesizer is programmed by a microcontroller which controls which carrier frequency is selected by the user. The output of the Modulator is a frequency modulated carrier that consists of the video information and the audio inter-carrier sidebands, which are 5.5MHz away from the carrier. The FM signal is then sent to the PA block which consists of a pre-amplifier and a power amplifier whose power output can be adjusted from 1mW to 300mW. The output of the PA block is fed to a frequency trap to reduce the 1 st and 2 nd harmonics of the carrier and then routed to the antenna port.

Power on transmitter and set to channel 1 operating frequency. 2. Adjust the output power to 300mW using R23. The current draw at 300mW should be around 500mA +/- 50mA. 3. Verify sub-carrier presence and adjust carrier offset by adjusting L2. The offset should be 5.5MHz. 4. Adjust deviation constant by adjusting R1 and measuring the level of video at C8. The proper deviation constant is reached when the peak to peak amplitude of video is .25V. 5. Sweep frequencies from 10MHz to Carrier noting signals exceeding 46dBuV. Make any repairs if necessary. Record any levels within 6dB of limit. 6. Verify 1 st and 2 nd Harmonic levels not to exceed -39.2dBc. Make any repairs if necessary. Record any levels within 6dB of limit. 7. Repeat Steps 4 and 5 for channel 2 operation as well.

Radio RF Safety Calculator Interpretation of Results 1. Remember that the power value entered into these calculations should be the average power seen at the antenna, and not Peak Envelope Power (PEP). You may also consider feedline loss in calculating your average power at the antenna. 2. If you wish to estimate the power density at a point below the main lobe of a directional antenna, and if the antenna's vertical pattern is known, recalculate using the antenna's gain in the relevant direction. 3. Please also consult FCC OET Bulletin 65. It contains a thorough discussion of the RF Safety regulations as they apply to exposure limits and contains numerous charts, tables, worksheets, and other data to help determine station compliance.

The following certification numbers have been issued in recognition of these accreditations and certifications: FCC Registration Number: 89450 Industry Canada Lab Code: IC 4175 VCCI Member Number: 1831 ƒ VCCI OATS Registration Number R-1526 ƒ VCCI Conducted Emissions Site Registration Number: C-1608 2.1.1 Open Area Test Site The open area test site consists of a 40’ x 66’ concrete pad covered with a perforated electro-plated galvanized sheet metal. The perforations in the sheet metal are 1/8” holes that are staggered every 3/16”. The individual sheets are placed to overlap each other by 1/4” and are riveted together to provide a continuous seam. Rivets are spaced every 3” in a 3 x 20 meter perimeter around the antenna mast and EUT area. Rivets in the remaining area are spaced as necessary to properly secure the ground plane and maintain the electrical continuity. The entire ground plane extends 12’ beyond the turntable edge and 16’ beyond the antenna mast when set to a 10 meter measurement distance. The ground plane is grounded via 4 - 8’ copper ground rods, each installed at a corner of the ground plane and bound to the ground plane using 3/4" stainless steel braided cable. The turntable is an all aluminum 10’ flush mounted table installed in an all aluminum frame. The table is remotely operated from inside the control room located 40’ from the range. The turntable is electrically bonded to the surrounding ground plane via steel fingers installed on the edge of the turn table. The steel fingers make constant contact with the ground plane during operation. Adjacent to the turntable is a 7’ x 7’ square and 4’ deep concrete pit used for support equipment if necessary. The pit is equipped with 5 - 4” PVC chases from the pit to the control room that allow for cabling to the EUT if necessary. The underside of the turntable can be accessed from the pit so cables can be supplied to the EUT…
