Rev. 00Page 3 1.0INTRODUCTION This document describes the procedures required to properly tune a Strata System with the TR4022 board. Many of the adjustments for the Strata are pre-tuned during the manufacturing test process therefore adjustments required in the field have been minimized. Adjustments such as center frequency and sweep are preset for 8.2 Mhz operation. If the system is required to detect a different frequency tag the sweep range will need to be readjusted by the installer. Once properly configured, if poor performance results, the CSE should direct their efforts toward finding the source of the interference in the environment. Several test signals are provided by the TR4022 board, which may be viewed on an oscilloscope. These signals allow the CSE to identify and measure ambient noise levels, resonances and other sources of environmental interference. The DSP (digital signal processor) system automatically subtracts stationary resonances seen by the antennas. The system offers flexibility to adjust for these circumstances. However, the solution for environmental problems, is to determine the environmental problems and resolve them. The options for adjusting to environmental problems are performed both in the analog and digital realm by the technician. The analog solutions are reducing power on the transmit antennas (2-loop and/or 3-loop), reduce the baseband gain, and adjust the sweep. In the digital toolbox there are four user selectable filter parameters. These tools should be used only after the CSE has attempted to correct the environment. The Strata system is powered by a +24Vdc power supply, P/N 121878. This power supply can power up to a maximum of three antennas. 2.0SYSTEM DESCRIPTION The Strata system is a transceiver design using both a 3-loop, 2-loop, and a 1-loop antenna design. The Strata alternates between using the 2-loop antenna and the 3-loop antenna. The 1-loop antenna is used as a shield that is tied to ground. This technique provides the system with different views of the detection field allowing the system to improve detection by minimizing the holes typically found at the crossbars of typical swept antennas. During an antenna’s cycle, the system performs two “blasts” which are called a “bin”. There are sixteen bins per frame. A bin consists of two “noise” cycles and two blast cycles, a blast is a transmit cycle and then a receive cycle. During the noise cycle, the system is not transmitting, only receiving ambient noise. This allows the system to establish the baseline noise level of the environment for later comparison. The system then transmits or “pulses” the field and then receives or “listens” for an echo of a tag signal. This frame is repeated on the other antenna. A tag response need only be present on one of the antennas to cause an alarm. In effect the system provides the best o…
