Advanced Telemetry Systems R4500S User Manual Advanced Telemetry Systems, Inc. R4500S Reference User Manual R02-06-A 2 Introduction: The R4500S is a receiver - data logger combination with built in GPS. (An optional GPS antenna is required to use the GPS feature) Operationally, the R4500S works by acting as a filter to select a very narrow window in the frequency spectrum. The position of this filter in the frequency spectrum is determined by the frequency selection (tuning). The receiver rejects signals and noise outside the filtered window, and passes signals and noise within the window. Additionally, the receiver translates the signal to a frequency within hearing range that can be heard from the speaker. The R4500S can store 98304 Stationary data blocks, or 49152 Aerial data blocks or data blocks recorded in the Manual mode. For Aerial Data, and data recorded in the Manual mode, an extra data block is needed for GPS information. The data is stored to memory using a looping format. If the data set is maxed out, the newest data will overwrite the oldest data block. Data blocks consist of the time stamp, frequency, transmitter data, and GPS location if GPS is used. The Receiver uses DSP (Digital Signal Processing) technology to achieve better sensitivity, and to help filter out noise. The DSP digitally samples the audio signal from the R4500S. When the signal has been digitized, the DSP processor uses internal mathematical calculations to identify signals. The S suffix indicates the software in this receiver is programmed to detect non coded transmitters. A non coded transmitter transmits a single pulse which is repeated at a specific pulse rate. The R4500S can be used for fixed pulse rate transmitters, and for variable pulse rate transmitters. For fixed pulse rate transmitters, the R4500S uses a pattern matching algorithm to detect up to 3 user entered pulse rates. To verify a pulse rate, the pattern matching algorithm uses 4 pulses from the transmitter to verify the pulse rate which helps separate a transmitter signal from a noise pulses. This is important to know for setting the correct scan time for detecting pulse rates as described in sections 13.0 – 15.0. For variable rate transmitters (temperature, depth, altitude), the R4500S uses a pattern matching algorithm to identify transmitter pulse periods, and converts the period to the actual measurement using 2 nd order regression coefficients required to be entered for each transmitter. Class B Device Statement: (Section 15.105 (b) of the FCC Rules) “Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. o Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. o Consult the dealer or an experienced radio/TV technician for help.” Advanced Telemetry Systems, Inc.

Possibility of Cell Phone Reception R4500 Telemetry Receiver Advanced Telemetry Systems, Inc. 470 1 st Avenue North Isanti, MN 55040-0398 Regulatory concerns related to the possibility of monitoring cell phones are addressed in several ways: 1). there is no option for FM or PM demodulation, a requirement for cell phone reception. 2). the narrow bandwidth of the IF filter would severely distort the signal making most conversations unrecognizable. 3). the receiver front ends are fix tuned which would not pass the cell phone band. 4). the VCO tuning range is limited to approximately 250MHz by the components used. It would be impossible to receive cell calls because hardware constraints limit the frequency range below the cell phone range and there are no demodulation circuits for FM or PM.
