Both the receiver and the transmitter are synthesizercontrolled via Phase Locked Loop (PLL) circuitry for clear, steady radio frequency(RF) signal. The receiver is available in either dual or single models that fit into a stan-dard 19 inch (482 mm) equipment rack. An auxiliary unswitched AC output jack al-lows multiple receivers to be linked “daisy chain” style. The optional UA830 RemoteAntenna Kits can be powered by 12 Vdc, 500 mA output provided through the anten-na connectors. The optional UA840 Antenna Distribution Amplifier Kits allows con-nection of multiple receivers using only two antennas. SYSTEM FEATURES Shure UHF Wireless Systems offer many exceptional features, including: • Frequency Agility. The operating frequency of transmitters and receivers can be easily switched to any setting in the UHF range. Settings are available in pre-pro-grammed incremental steps that allow for necess…

The tests were performed according to the procedures of FCC as stated in Part 2 Subpart J, Equipment Authorization Procedures of the Code of Federal Regulations 47, by personnel of D.L.S. Electronic Systems, Inc. who are responsible to Donald L. Sweeney, Senior EMC Engineer. 3.0OBJECT The purpose of this series of tests was to determine if the test sample could meet the radio frequency emission requirements of the FCC "Rules and Regulations", Part 74, Subpart H, Sections 74.801 to 74.882 for Low Power Auxiliary Stations operating in the 692 - 716 MHz Frequency Band. 4.0TEST SET-UP All radiated emission tests were performed at D.L.S. Electronic Systems, Inc. The radiated tests were made with the test item placed on a wooden turntable located in the Test Room with the receive antenna placed one meter from the device under test. EMC Test ServicesReport No. 6994 1250 Peterson Drive, Wheeling, Illinois 60090, USA07/05/01 Page 8 5.0TEST EQUIPMENT (Bandwidths and Detector Function) All data was automatically plotted using peak detector function. This information was then used to determine the frequencies of maximum emissions. Manual measurements were performed on these frequencies using a peak detector function of the Analyzer with the bandwidths specified by the FCC. From 200 MHz to 1000 MHz a bandwidth of 100 kHz was used (except for Occupied Bandwidth), and above 1000 MHz, wide enough bandwidths were used, depending upon the test being made, to ensure proper measurement of the narrowband signal. A list of the equipment used can be found in Table 1. All equipment was calibrated per the instruction manuals supplied by the manufacturer. 6.0RF POWER OUTPUT - PART 2.985 As stated in PART 74.861 (e-1), the output power should not exceed 250 milliwatts (24 dBm). The U1B UHF-FM Body Pack Transmitter was tuned according to the tune-up procedures specified in Part 2.983 (d-5), and adjusted for its maximum output power. The RF output power was measured in the open field, using the following test method: The radiated signal from the EUT was measured. The EUT was then substituted with a signal generator and a tuned dipole antenna. The output of the signal generator was increased until the level received by the tuned dipole equaled that of the previous measured from the EUT. Actual Measurements Taken: 10.6dBuV Measured output of the transmitter +0 dBuV Total system losses (Antenna, Pads & Cable) 10.60dBuV which equals 0.01 watts LIMIT: Manufacturer's rated output power = 0.01 watts Tolerance = 100 ppm MARGIN: 0.25 watts - 0.01 watts = 0.24 watts NOTE: See the followi…
