ii WARNING! RF RADIATION EXPOSURE HAZARD This warning is provided by Broadcast Microwave Services (BMS) Inc. for safety purpose. The following information help to reduce the risk of RF exposure hazard. FCC Limit of RF Exposure According to Federal Communication Commission (FCC), the Maximum Permissible Exposure (MPE) for FR radiation has been set to 1.0 mW/cm2 for the Field-Coder II equipment (OET Bulletin 65). The Field-Coder II with Power Amplifier is a non-broadcast transmitter and without an antenna it will not create RF exposure (power density) exceeding the 1.0 W/cm2 FCC limit. However a high-gain antenna such as a parabolic dish will greatly enhance the Field-Coder II output power density beyond the MPE limit of 1.0 mW/cm2. In this situation a minimum distance from the antenna needs to be calculated in order to keep the MPE always below the safety limit. The calculation has been done for Field-Coder II based on the formula mentioned in OET Bulletin 56. The calculations have been done for different commonly used antenna in Electronic New Gathering (ENG) systems. Digital Transmission Figure 1 shows the plot of the minimum exposure distance for 0dBi, 5dBi, 16dBi, and 30dBi antennas. The 2 GHz Field-Coder II with Power Amp transmits the maximum power of 5 Watts. The minimum exposure distances are found from the cross points of the exposure graphs (for various antennas) with the line of maximum permissible exposure (i.e. 1 W/cm2). Notice that the numbers in Figure 1 predict the worse case scenario, which is straight in front of the antenna (exposing to the antenna main-lobe). Obviously the side-lobe exposures are well below these numbers as the radiation intensity dramatically reduces on the side lobes.

1SYSTEM DESCRIPTION The Field-Coder II system is a portable 1W digital transmitter for wireless transmission of video, audio, and user defined private data. Built on the same platform as the field proven Carry-Coder II, the FCII has many of the same features and capabilities. Figure 1 FCII Architecture Block Diagram The FCII supports 2 audio (analog) inputs and one video (CVBS, SDI or ASI) input. The FCII includes an MPEG2 encoder and a DVB-T compliant COFDM modulator. Both MPEG and COFDM parameters are fully configurable by the system controller in support of optimum performance and compatibility with other equipment. For those users less familiar with detailed COFDM and MPEG settings, there are 3 preset robustness settings (low, mid and high) that each optimize video performance at the expense of modulation complexity. High robustness provides the lowest quality video but is able to operate in severely compromised locations. Low robustness provides the best quality video but may require a clear line of sight shot. An auxiliary data channel is provided that can be configured to transmit data (GPS, etc.) at baud rates up to 9600 bps. The FCII can be controlled directly through the Front Panel or remotely. Configurations of the FCII The FCII can be used: • Independently – when supplied with +12 to + 32 VDC • With the FCII-AC (AC to DC Power Converter) – to power the FCII from AC source • With Both the FCII-MAX and FCII-AC – FCII-AC powers both the FCII and FCII-MAX
2 The FCII-AC is a weatherproof AC/DC power supply that can be used to power both the FCII and the FCII-Max from 110/220 VAC. As a stand alone unit, the FCII is a 1 W digital transmitter. The FCII – MAX will increase the power output to 5W, significantly increasing the transmission range and robustness. Conveniently, the FCII-MAX can also be powered by the FCII-AC.

7FCII SET-UP with FCII-AC and FCII-MAX The FCII can also be used with the FCII-AC and the FCII-MAX together. Using the brackets (BMS p/n 4414203001) to join the three components, and installing the quick disconnect tripod mounting plate to the bottom of the FCII-AC will speed up field set-up. The FCII-AC should be placed on the bottom of the stack, with the FCII in the middle and the FCII-MAX on the top. The preparation for quick field set-up is as follows: • Tripod Quick Disconnect Mound Installation to the FCII-AC (if applicable) • Installing Antenna bracket quick disconnect Mount to the FCII-MAX • Attaching the FCII, FCII-AC and the FCII-MAX together • Cable Interconnections Installing the Tripod Quick-Disconnect Mount to FCII-AC Please follow the procedures in section Error! Reference source not found. Error! Reference source not found. to install the tripod quick disconnect mounting plate to the FCII-AC. Attaching the FCII, FCII-AC and FCII-MAX together When using the FCII with the FCII-AC and the FCII-MAX it is convenient to stack them all together. The stack order is as follows; FCII-AC on the bottom, FCII in the middle, and the FCII-MAX on top. This allows for proper access and adequate cooling for each component. The FCII components are designed to be stacked on top of each other and secured by simple brackets on either side. There are 6 sets of threaded holes, 3 pair forward, 3 pair toward the back, on either side of the components. There is no real requirement for which sets are used provided the load is distributed both front and back and the components are stacked flush with each other. Tools Needed: #2 Phillips Head screwdriver The design of the FCII-AC requires that it is placed on the bottom of the stack. Use 4 #10-32 screws to secure, but do not tighten, two brackets, one forward, one back to one side of the FCII-AC. Use 4 #10-32 screws to secure, but do not tighten, the two brackets on the opposite side of the FCII-AC. Align the FCII so that it is facing the same way as the FCII-AC.
8Slip the FCII in between the brackets. Secure the FCII to the brackets using the matching hole set used on the FCII-AC. The FCII should be stacked directly on top of the FCII-AC, not staggered. Tighten all screws. The FCII-MAX power amplifier requires proper heat transfer. The FCII-MAX needs to be on the top of the stack. Use 4 #10-32 screws to secure, but do not tighten, two brackets, one forward, one back to one side of the FCII. Use 4 #10-32 screws to secure, but do not tighten, the two brackets on the opposite side of the FCII. Align the FCII-MAX so that it is facing the same way as the FCII-AC and FCII. Slip the FCII-MAX in between the brackets. Secure the FCII-MAX to the brackets using the matching hole set used on the FCII. The FCII-MAX should be stacked directly on top of the FCII, not staggered. Tighten all screws. Figure 2 is an example of one way to install the brackets used to attach the FCII-AC, FCII and FCII-MAX together.
9 Figure 2 FCII-AC, FCII, and FCII-MAX Bracket Attachment Cable Interconnections To hasten field set-up time, it is advantageous to have some of the interconnect cables already connected. The cable connections between the three components are as follows: The power cable from the FCII-AC to the FCII The power cable from the FCII-AC to the FCII-MAX The RF cable from the FCII to the FCII-MAX, this cable is connected in the field after the Horn Antenna is mounted. The power connection DC to FCII on the FCII-AC to the power input connector on the FCII located right below the ON OFF switch. To connect the power connection from the FCII-AC to the FCII, align the connector, matching the keys on one side to the grooves on the other.
10Slide the connector into place and twist connector housing to secure. Repeat for connecting the cable to the FCII. To connect the power cable from the FCII-AC to the FCII-MAX, remove the attached connector cover.

30Coded Orthogonal Frequency Division Multiplex (COFDM) Modulation COFDM is used for microwave applications like wireless cameras and mobile video links because of its tolerance to multipath transmission errors. In addition COFDM offers more than twice the spectral efficiency of comparable FM analog microwave transmission. COFDM does not rely on the vulnerability of a single carrier but spreads the digital information over many narrow band carriers using Frequency Division Multiplex (FDM). The bandwidth and the data rate on each of these carriers are reduced and therefore the RF robustness is increased. The carriers are accurately spaced and orthogonal, which means they can be generated and recovered without carrier specific filtering. Even though the spectra of adjacent carriers significantly overlap, each carrier can be demodulated without crosstalk from its neighbors. The main COFDM parameters are: • Number Of Sub-Carriers (About 2,000 In Our Case) • The Symbol • Individual Sub-Carrier Modulation • Guard Interval (GI) Duration Between COFDM Symbols • Data Redundancy Code Rate Used For Error Correction Symbols The active symbol is the period that digital information is sampled. The number of bits carried in each symbol depends on the choice of modulation. Modulation Modulation is the process of varying a carrier signal in order to use that signal to convey information. Quadrature amplitude modulation (QAM) is a modulation scheme which conveys data by changing (modulating) the amplitude and phase of two carrier waves. BMS uses the forms QPSK, 16QAM, and 64QAM. QPSK 2 bits/symbol 16 QAM 4 bits/symbol 64 QAM 6 bits/symbol The higher-order QAM has a higher susceptibly to noise and other corruption. 64QAM will transmit more bits per symbol but with higher bit error rate. It is a less robust signal, but over an easy transmission path (studio setting) it probably won’t matter. More difficult transmission paths (mobile or aerial over long ranges with lots of interference from trees and buildings) will require a more robust signal. Guard Interval (GI) The guard interval acts as a buffer to protect the active symbol from echoes. A guard interval is added to the beginning of each symbol to allow time for echoes to settle before beginning the active symbol period. A wide range of guard interval options are available from  to . This fraction represents the ratio between the guard interval to the active symbol period. This Page Intentionally Left Blank
31 Code Rate The code rate represents the amount of Forward Error Correction (FEC) used for each active symbol. FEC is a method of obtaining error control in data transmission. A code rate of ½ means that for two bits of information received, 1 bit is the real data. The other bit tells how intact the first bit is. A code rate of 7/8 means that out of the 8 bits sent, there are 7 bits of real data and only 1 bit that is to catch any errors in those 7. Transmission Rates Finding the best transmission mode to suit a given situation means selecting the best compromise between modulation, guard interval and code rate. What follows are the ETSI EN 300 744 V1.4.1 (2001-01) standards for the useful bitrate (Mbit/s) for all combinations of guard interval, constellation and code rate for non-hierarchical systems for 6, 7, and 8 MHz channels respectively.
