Preco Electronics Inc. PV2000 TIME DOMAIN RADAR PV2000 USER MANUAL CLYDE SHAVER 3-1-2000 INTRODUCTION This manual will discuss the installation and operation of Preco’s PV2000 Time Domain Radar. General radar and electro-magnetics theory will be left for the reader to pursue elsewhere. INSTALLATION The radar was designed to be mounted perpindicular to the ground at a height of 3 feet (ground to center of radar). Mount radar at the rear of the vehicle, in the center. If radar must be mounted at a height of less than 2.25 feet, then radar unit must be tilted Up aprox 5 degrees, to keep the ground from being detected. If radar is mounted at greater than 4 feet, then radar can be tilted down aprox. 5 degrees to avoid missing short Targets within the range. Connect the two conductor dc power connector to a dc supply of 9.6v-28volts. Connect the round connector on radar sensor to the extention cable that goes up to the cab of the vehicle, and connect LED box to extension cable. OPERATION The radar is designed to detect objects up to 8 meters(26.25 ft). The eight lights indicate How far target is from radar unit. When 1 light is on, a target has just entered the detection zone at 8meters away. When all 8 lights are on the target is within 1 meter of The radar sensor. The audible indicator also beeps faster as the target approaches. The radar was designed to meet SAE J1741, see spec. for zone parameters. The PV2000 has a detection zone that resembles a pear, see zone pattern plot. The vertical pattern is aprox. 20 degrees thruout the range and the horizontal is about 150 degrees at 0.5 meters, and about 45 degrees at 26 feet. RADAR DETECTION ZONE DIMENSIONS ARE IN METERS HORIZONTAL PATTERN VERTICAL PATTERN

From: Clyde Shaver Preco Inc. [email protected] To: Joe Dechoso Date: 4-28-00 Re: FCC ID OXZPV2000 731 Confirmation Number EA97146 In Response to Correspondence Ref. Number 13583 Date of Original E-Mail 4-21-2000 Dear Joe Dechoso, 1) See Attracted Confidential letter that list exhibits Preco wants held Confidential. 2) Preco’s PV2000 radar has a center frequency of 5.80 Ghz. The Pulse Repetition frequency is 5 Mhz. This radar was designed to meet FCC part 15 for Transmitters, by lowering the power Out of the transmitter to below the noise floor. (-54dB uV/Meter @ 3 meters) Transmitters below this level are considered to be a non transmission, and pose no Threat to any equipment in its proximity. We have compared our Transmit power level to other products, at the same frequency, And the same Pulse length (10-12 Nano seconds). We found our radar transmits the same or less energy than Sentrol Corp’s product that uses the same pulsed RF technology. HP Application note 150-2 contains the desense chart and parameters the determine is the Desense is applicable. We find that like the app. Note states, that if the PRF of the transmitter is less than the Video BW of the Spectrum Analyzer, the factor does not apply. We find that at the output power levels of our transmitter, even with a PRF of 10 Mhz does not require a Desense factor. At 1.25 Mhz or 2.5 Mhz or 5Mhz the output power Does not change and the factor does not apply. We attribute this to high dynamic range Spectrum Analyzer, and that until the power level reaches greater than 1mW the internal mixer does not go non linear, and the filters do settle and give accurate readings. HP produced an abstract named Pulsed-RF Measurements: Considerations in Using Spectrum Ana lyzers Author: Joe Gorin (R&D Engineer with HP. Abstract does not have a number, I only have this in hard copy form. If you don’t have this abstract, and would like a copy, please feel free To request it, and I can scan, or fax it to you. This 15 page abstract was presented at a RF & Microwave Measurement Symposium This abstract covers Spec. An considerations when measuring Pulsed-RF transmitters. Subjects covered Accuracy degradations: 1) Video-response errors 2) Dynamic-range Limitations 3) Misresponses to pulses 4) Time-domain aberrations. Measures of spectrum-analyzer performance: 1) Sensitivity-related figures of merit 2) Repeatability 3) Performance comparisons We concur in the lab with this abstract. Power levels measured into a HP 8590 series analyzer that are at or below –10dBm are not distorted power wise because of the dynamic range of the analyzer. Intertek Testing Services has been through these same measurements, and concur with these findings. Thanks for your time and Consideration 208 850-6510 cell 208 322-2444 office

Clarification that only the schematics were to be held confidential. • Please hold the schematics confidential. The block diagram and theory of operations are not confidential. Thank you for helping us clarify these confidentiality issues. 2. A response to item #2 of your FAX ref:14289 dated 26MAY00 asking for Data on the carrier, 5.8 GHz and the harmonics; • Enclosed you will find PV2000 FCC 15.249 Radiated Emission data and graphs running the device CW, in Continuous Mode, rather than pulse with data at the fundamental, attached CW1, and first harmonic,attached CW2. Although Pulse Mode is the normal operation of this device we have included this CW information, as did Sentrol (FCC Identifier CGGAA2) in their application and subsiquent certification for the same frequency band and certification type of field disturbance sensor. This Continuous Mode data helps demonstrate that our device operates within Specification for both the Continuous Mode as well as Pulse (Modulated). Intertek Testing Services (ITS) concurs with this test method. • Also included is the page from our ITS test report that contains the measured harmonic content of the carrier, the measurements on both sides of the carrier, and the harmonics through 40000 MHz. This was extracted from our original test report Please refer to original data submitted on test report # J99032486b, test date of 1/11/2000 for additional harmonics FCC 15.249 Radiated Emissions. I have included the same Sentrol FCC 15.249 Radiated Emmissions data for reference and comparison. • 3. In response to your request to provide any supporting measurement information: • ANSI C63.4 -1992) Appendix H4 note between step 11 and 12. instructs one to refer to the test equipment manufacturer for proper measuring correction factors when measuring pulses. We called Agilent Technologies Measurement support group (formerly HP Test and Measurement) for spectrum analyzers to review the desensitization factor applicability. We were referred to Mr. Carlos Perez, a 31- year veteran Engineer specializing in spectrum analyzer measurements, as their “resident expert”. • In reference to HP Application Note 150-2 Spectrum Analysis Pulsed RF. On page 15 sentence 1, “There are several conditions which must be satisfied if equation (10) is to be valid.” Mr. Perez stated that all four conditions must be satisfied for the Pulse Desensitization Chart (Figure 28) to be applicable. In particular, condition 4. Peak amplitude at the mixer of the analyzer must stay below the 1 dB compression point of the analyzer (typically between –10dBm and –5dBm). • Our peak power at 5.8 Ghz in CW mode is less than –30 dBm. • Mr. Perez continued to clarify by saying that when the application note was first written (1971), the spectrum analyzers at the time had no warning mechanism to alert an operator, that he/she was exceeding the input power level at the spectrum analyzer input causing the input mixer or amplifier to saturate. Mr. Perez explained that if in doubt, whether or not an operator is over-driving the analyzer, the operator should decrease the input power into the analyzer by 10 dB, and observe the change in the reading. If the signal displayed only drops 9 dB, then the analyzer has reached the 1 dB compression point. (This is partial saturation). If the displayed reading goes down 10 dB, then one knows that the input power level into the analyzer is in the linear range, and the measurements displayed do not require any addition correction factor to be applied, because the analyzer is not in compression or partial saturation. • In reference to HP 150-2 Application Note, page 17, first paragraph, if we keep input signal levels at or below –10dBm (assuming this is the 1 dB compression point), we are the limited only by the sensitivity of the analyzer. This is the point that Mr. Perez was trying to emphasize. The last sentence of the application note says, ”The new generation of HP spectrum analyzers offers exceptionally high sensitivities which allow measurements of extremely short RF pulses” This is the case now, and even then (1971), as long as you don’t saturate the analyzer and you have sufficient display range (30 dB in our case). • Mr. Perez is available as a resource to discuss the Application Note 150-2 interpretation with the FCC. His telephone number is (800) 452-4844. 4. Based upon the data taken by ITS, close review of when to apply desensitization, and prior decisions by the FCC, as demonstrated in Sentrol’s certification CGGAA2, we do not believe the application of 26 dBm correction factor is appropriate in this case. Both Intertek Testing Services and HP’s expert concur with this view. The following materials are included in this response. 1. FCC15.249 Radiated Emissions, 1/11/2000,ITS #J99032486 2.
