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…

UNISYS PCTC Product Compliance Test Center 2476 Swedesford Road, Malvern, PA 19355 May 25, 2000 FCC Application Processing Branch Correspondence Reference Number: 14198 Applicant: Checkpoint Systems, Inc. 731 Confirmation Number: EA97409 Product: Strata MX FCC ID Number: DO4STRATAMX Gentlemen, Please accept the following responses to the questions posed through E-Mail on the above referenced product. Question 1: The equipment did not list an antenna below 25 MHz. Please list the antenna used. Response 1: Our procedures for performing measurements in the frequency range below 30 MHz for products such as the Strata MX requires the primary use of a magnetic field loop antenna. The measurements documented in the test report submitted for the Strata MX were recorded using a loop antenna manufactured by ARA, Model BBH-500/B, which is capable of calibrated measurements through the frequency range from 300 Hz to 100 MHz. Question 2: Section 15.31(m) requires two frequencies to be tested due to the requested frequencies. Please provide test data at a frequency near the top of the requested frequency band. Response 2: I am interpreting your question/comment to mean that a second measurement is being requested in the 1.704 MHz to 10 MHz band because there appears to be multiple operating fundamental frequencies for the product. Our interpretation of this section was that additional measurements in the 1.704 MHz to 10 MHz band are necessary only when the product under test is capable of being operated at alternative or multiple fundamentals within this band. This product is only capable of operating on the one fundamental, which is defined as being centered on 8.2 MHz and having a 1.2 MHz bandwidth. For this reason only one measurement is presented in the report for the fundamental. It represents the maximum emission level recorded over the 1.2 MHz band of the defined fundamental. It might be helpful to provide a description of the method of operation of the product to help in clarifying our reasoning. The purpose of this product is to detect the presence of Article Surveillance Tags placed on merchandise as a means to deter theft. By its design, the product uses a pulsed, digital hopping, transmitter to detect the presence of an Article Surveillance Tag. These Tags respond by resonating in the 8.2 MHz region when subjected to a pulsed radio transmissions from this product. A Direct Digital Synthesizer (DDS) on the control module, generates a sequence of 16 discrete frequencies from 7.6 MHz to 8.7 MHz (digital sweep). The list of available frequencies are as follows: 7.600708 MHz7.673950 MHz7.747192 MHz7.820435 MHz 7.893677 MHz7.966919 MHz8.040161 MHz8.113403 MHz 8.186646 MHz8.259888 MHz8.333130 MHz8.406372 MHz 8.479614 MHz8.552856 MHz8.626099 MHz8.699341 MHz The restricted bands in this area are: 8.291 - 8.294MHz 8.362 – 8.366 MHz 8.37625 – 8.38675 MHz 8.41425 – 8.41475 MHz Per Section 15.205, the transmitter is not capable of hopping into or operating in, any of the restricted frequency bands. The generation and transmission of these 16 discrete frequencies constitutes the fundamental, which is centered at 8.2 MHz and has a 1.2 MHz bandwidth. A plot of the fundamental can be found in Section 6.1.2 of the submitted report. This plot shows the overall shape of the fundamental and its associated bandwidth. Although there are 16 individual frequencies listed, together they constitute the fundamental operating frequency or frequency band of the device. They are not 16 individual fundamentals. Based on the operation of the device, we interpreted the complete transmission pattern as the fundamental, and measured the worst case accordingly. There are no other intentional radiator emissions present within the 1.704 MHz to 10 MHz band that can be attributed to the operation of this product. 3) I must also respond to your comment regarding the ED GIBBONS correspondance. The products designed and manufactured by Checkpoint Systems have always been of the pulsed, digital hopping, transmitter type. Checkpoint Systems approached the FCC with the intention of clarifying the measurement method to be used for their particular products. The letter from Mr. Gibbons describing the procedure to measure the emissions from their transmitters was a result of conversations between the two parties. So I feel I must disagree with your interpretation. The correspondence was meant to describe a measurement method for their particular pulsed digitally swept frequency system that hops on discrete frequencies. We are also aware of the ban on hopping into the restricted bands. This product incorporates the use of a discrete digital synthesizer to generate the particular frequencies to be used to constitute the fundamental. The specific frequencies used by the transmitter are shown above along with the appropriate restricted bands within the 7.6 MHz to 8.7 MHz region. The transmitter is incapable of hopping into the restricted bands. I hope these responses satisfy your questions.
