Within that band, it uses a minimum 200-kHz bandwidth, on one or two channels, each with a 800-kHz maximum bandwidth, depending on the selected data rate. The user is responsible for inquiring about local radio frequency regulations and using the frequency band accordingly. The LRU unit operates from a 10.5 VDC to 15.0 VDC power supply voltage. The power supply should be capable of generating a minimum current of 15 A. A 12 VDC battery can be used as a power supply. The power supply used shall be compliant with the rules and regulations of the FCC, of Canada or with other local regulations. The antenna impedance to be used is 50 Ohm. The maximum VSWR is 1.7:1 at the operating frequencies. The allowable temperature range for both operating and storage is -40°C to +70°C. The LRU unit comes with standard 408UL Transverse, Line, Power and XDEV connectors. The Type-N, radio connector is waterproof when connected. Attention should be paid to put the cap in place on the radio connector whenever the unit is not in use, in order to keep the connector clean and the unit waterproof. The LRU relay is a half-duplex transmission system. With "Field ON" activated in the Line main window on the HCI, the unit connected to the side towards the Central Unit continuously transmits a time tick signal (every 50 ms) that allows the other end to keep clock-synchronized. Supplied along with each LRU relay are two 7-elements antennas and two 6- to 8-m telescopic portable masts.

Half-duplex In the LRU transmission protocol, time is shared between transmission of Master-to-Slave messages and transmission of Slave-to-Master messages. Master-to-Slave messages are called Network Control Sequences ( NCS ), used for synchronization, zero-time transmission and control. Slave-to-Master messages are called Data Transfer Sequences ( DTS ), used for data retrieval, seismonitor and collecting test results. Typically, NCS messages are transmitted every 50 ms. In reply to an NCS message, the Slave LRU transmits a DTS message. LRU LRU DTS NCS (Master) (Slave) NCSDTSNCSDTS (50 ms) (50 ms) Radio frame time Theory of operation 1-4 March 2002 LRU frequency management The RF transceiver in the LRU unit uses a single 2-MHz band for both transmission and reception. That band is selected between 216 MHz and 249 MHz using the “Center Frequency” parameter. Within the 2-MHz bandwidth, you can choose which channel(s) to use for NCS and DTS messages, by specifying: •a Control Channel Frequency for NCS messages, •a Data Channel Frequency for DTS messages. The necessary bandwidth for a Data Channel depends on the expected Data Rate (256, 512, 1024 or 2048 kbps). See the diagram on page 7-5 . The RF transmission i…

5.0 - ELECTROMAGNETIC COMPATIBILITY TEST DATA 5.1 - General Electromagnetic compatibility testing is divided into sections, as follows: a) HP141T Spectrum Analyzer Detector, b) IFR Spectrum Aalyzer c) Site Calibration d) Receiver Tests e) Transmitter Tests 1) Antenna Conducted Spurious Emissions a 2) Case Radiated Spurious Emissions Measurements were made from 30 Mhz to 40 Ghz on the receiver and transmitter, using an IFR A-7550 Spectrum Analyzer, SN 2347 and an HP141T Spectrum Analyzer, SN 2205A21383 with calibrated mixers. The IFR A-7550 was used for measurements below 1000 Mhz. 5.2 - Hewlett Packard 141 T Spectrum Analyzer Detecter The HP141T Spectrum Analyzer system 3 Db IF bandwidth or resolution bandwidth was set to 10 Khz for all measurements. The FCC requires a bandwidth of 4 Khz. Therefore the observed data is 10 log (10/4) = 4.0 Db too high. The noise bandwidth, for the HP141T system, as defined by Hewlett Packard Application Note 150-4, April 1974, is 1.2 times the three Db bandwidth. Therefore the observed data is an additional 10 log (1.2) = 0.8 Db too high. From the previously mentioned application note it is stated that "the detected signal is smaller than its true rms value. This correction for the log display mode combined with the detector characteristics gives a total correction of 2.5 Db, which should be added to any random noise measured in the log display mode. " The summation of corrections is as follows: - 4.0 Db Bandwidth - 0.8 Db Noise bandwidth + 2.5 Db Detector characteristics - 2.3 Db Total The observed power levels are therefore 2.3 Db too high for noise or noise like random signals, for the HP analyzer. 5.3 - IFR A7550 Spectrum Analyzer Detectors For site calibration data from 30 - 1000 Mhz the peak detector was utilized, 200 Khz resolution bandwidth. The guidelines for Verification are set by the American National Standards Institute (ANSI)in C63.4-1992. These guidelines were originally set by the Comite International Special Pertubations Radioelectroniques (CISPR) and call for quasi-peak detection. On the A7550 Quasi-Peak measurements is valid only in the Linear Mode, with proper bandwidth. The quasi-peak detector utilized had a bandwidth of 120 Khz. The signal amplitude (in dbuv) is calculated from the formula A = T + X where: A = value in dbuv T = top of scale X = value from table, attached In conformance with the operating manual the A7550 was first used with the EUT turned off to null out the ambient spectrum. The ambient spectrum was nulled in steps of 30-100, 100 –200, 200-300 Mhz etc, as well as first looking at the entire band. We then stored the trace and subtracted it from the spectrum with the EUT on. Quasi-peak measurements were then made.

The OATS was constructed on a plywood platform, covered by a metal ground plane. It was located in a field adjacent to the Sercel Cable Manufacturing Plant. Sercel has three facilities on Park Row, in Houston, Texas. The coordinates, as taken by a Differential GPS and referenced to NAD83, were: 40:25:19.9 North Latitude by 086:52:19.1 West Longitude. Dates of testing were March 09, 10, 12, 13 & 14, 15 th, 2002. Hours of testing were 6:30 AM to 6:30 PM. We chose to work on Saturday and Sunday as rain was forecasted and did occur on Monday. The temperature at the site was roughly 62 degrees Fahrenheit/ 16.7 degrees Centigrade throughout the test period. 5.41 OATS Calibration Test Procedure Two Bicon Log Periodic Antennas were utilized. One an Emco 3143 calibrated to 1.7 Ghz by Emco. The second antenna was also a Bicon Log Periodic built by Antenna Research, model LPB 2520/A, rented from Teology. We picked up the EMCO 3143, 2075-2 motorized mast and 2090 Fiber-optic Controller at EMCO in Texas and drove to the site. The 2075-2 and 2090 were rented from EMCO. Three meter separation was kept between the centerline of the two antennas. The mutal impedance correction factors for broadband antennas equals zero. Attenuators were not found to be necessary to minimize cable reflections. In actuality we would have had to borrow coaxial attenuators because United Parcel Service (UPS) temporarily misplaced our tray of coaxial attenuators. We decided to try it without and found we were able to achieve the desired results. A Marconi 2022E Signal generator was utilized to feed the Antenna Research LPB 2520/A Bicon Log Peridic Antenna. This antenna was kept at a fixed height of 2 meters above the ground plane for the Horizontal Polarization, while the receive antenna was scanned from 1 to 4 meters in height, at three meters center - center of the two antennas. For Vertical Polarization the antenna was kept 1.0 meters off the ground plane while the receive antenna was varied from 1 to 4 meters in height. The equation used to calculate values was: An = Vdirect - Vsite - TXfactor - RXfactor where: An = Normalized Site Attenuation (db) Vdirect = reading with the two cables disconnected from the antenna and connected to each other via an adapter, in this case male to male type N. Vsite = reading re-connected to their respective antennas and with the receive antenna scanned in height from 1-4 meters, maximum reading recorded. Txfactor = Transmit Antenna Factor Rxfactor = Receive Antenna Factor Pictures of the OATS are attached as well as calibration data.

TEST REPORT KQ9LRU REQUEST FOR CERTIFICATION AND VERIFICATION DATA SUBMITTED BY: CONSOLIDATED SPECTRUM SERVICES 22 MERRILL DRIVE ATKINSON, NH 03811 ON BEHALF OF: SERCEL INC. 17200 PARK ROW HOUSTON, TEXAS 77084 1.0 - GENERAL INFORMATION 1.1 - Company Information SERCEL INC. is a well recognized leader in the oil and natural gas exploration markets. SERCEL INC is based in France with additional manufacturing and business headquarters in the State of Texas. The product herein described is set for a particular frequency of operation by country code at the factory. 1.2 - Description of Equipment Tested The KQ9LRU, also referred to as EUT, is used to measure geological characteristics that lie beneath the earth or ocean floor. It is used in cable and wireless applications. The unit is waterproof. The EUT consists of three main sections, which are: a) A protocol analyzer b) Modem or Mod/Demod Board c) RF Module The EUT in transmit mode, develops 6.0 Watts,nominal. It transmits in very short bursts during normal operation. It is typically polled from a central site. The KQ9LRU has data storage capability in its receiver section. It can also be used as a central unit or as a relay for a group of units. The EUT, is powered by a 12 V DC deep cycle marine battery source as provided by others. The EUT is intended for operation by prospective licensees in the 216 to 220 Mhz band, under FCC rule part 90.259. Operation is on a secondary basis to the maritime mobile and federal government services. 1.3 - FCC Rule Parts and Standards The EUT falls under FCC rule parts 2, 15 and 90. FCC rule part 90.203 (a) requires the EUT to meet the Certification process, for the transmit portion. In addition since the receiver operates between 30 and 960 Mhz and the transmitter is subject to certification, FCC rule part 15.101 (b) applies. This section requires the receiver portion to be subject to the verification process. FCC rule part 15.3 (k) defines digital devices and unintentional radiators. It states in part, "a radio frequency device that is specifically subject to an emanation requirement in any other rule part or an intentional radiator subject to subpart C of this part that contains a digital device is not subject to the standards for digital devices, provided that the digital device is used only to enable operation of the radio frequency device and the digital device does not control additional functions or capabilities." FCC rule part 2.1057 (a) (1) specifies the measurement range over which harmonics are to be measured for equipment operating below 10 Ghz. It states in part "to the tenth harmonic of the highest fundamental frequency or to 40 Ghz, whichever is lower." This unit has a fundamental frequency of 220 Mhz maximum. The highest oscillator in the unit operates at 336 Mhz. If we use the oscillator as the highest frequency, 10 times this would be 3360 Mhz. We measured to 40 Ghz for the Verification and Certification process, well exceeding the FCC specification. 1.4 - Technical Information The following tests and measurements were performed in the engineering laboratories of Sercel Inc., with the exception of Electromagnetic Compatibility Testing, which was recorded on a characterized open area test site, herein referred to as OATS. All equipment utilized was calibrated with an accuracy traceable to the National Bureau of Standards and American National Standards Institute (ANSI). All tests were performed under the direction of Howard Epstein of Consolidated Spectrum Services. We had two people from our company at the site, myself and an employee. 1.5 - Equipment Utilized A List of Equipment used for the tests is contained below along with the calibration due dates.
