General 2.0 Product Overview The MHX920 is a high-performance embedded wireless data transceiver. Operating in the 902 - 928 MHz ISM band, this frequency-hopping spread-
spectrum module is capable of providing reliable wireless data transfer between almost any type of equipment which uses an asynchronous serial interface. The small-size and superior RF performance of this module make it ideal for many applications. While a pair of MHX920 modules can link two terminal devices (point-to-
point operation); multiple modules can be used together to create a network of various topologies, including point-to-multipoint and repeater operation. Multiple independent networks can operate concurrently, so it is possible for unrelated communications to take place in the same or a nearby area without sacrificing privacy or reliability. 1.1 Features Key features of the MHX920 include:
transmission within a public, license-exempt band of the radio spectrum1 this means that it can be used without access fees
(such as those incurred by cellular airtime).
a serial I/O data port with handshaking and hardware flow control, allowing the MHX920 to interface directly to any equipment with an asynchronous serial interface.
ease of installation and use the MHX920 module uses a subset of standard AT style commands, very similar to those used by traditional telephone line modems.
all units in a system are physically identical, and can be configured as a master, repeater or slave using the AT command set. No hardware modifications are required
128 sets of user-selectable pseudo-random hopping patterns, intelligently designed to offer the possibility of separately operating multiple networks while providing security, reliability and high tolerance to interference.
encryption key with 65536 user-selectable values to maximize security and privacy of communications.
32-bit of CRC error detection and auto re-transmit to provide accuracy and reliability of data. 1 902-928 MHz, which is license-free within North America; may need to be factory-
configured differently for some countries. MHX-920 Operating Manual: Chapter2 General 1
TDMA (time division multiple access) support, allowing multi-slave access in point-to-point mode.
roaming ability, allowing repeaters and slaves to re-
synchronize with a new master if the synchronization pulse from the original master is lost. While the typical application for the MHX920 is to provide a short- to mid-
range wireless communications link between DTEs, it can be adapted to almost any situation where an asynchronous serial interface is used and data intercommunication is required. 2.1 Output Power Level The Output Power Level determines at what power the MHX920 transmits. The MHX920s sensitive receiver can operate with very low power levels, so it is recommended that the lowest power necessary is used; using excessive power contributes to unnecessary RF pollution. The allowable settings are from 100 mW to 1000 mW. Ideally, you should test the communications performance between units starting from a low power level and working upward until the RSSI is sufficiently high and a reliable link is established. The conditions will vary widely between applications, the output power settings can be calculated based on following information. Transmitter antenna gain Cable loss Effective radiated power (ERP) requirement by FCC Regulations Power Setting = 36 Antenna Gain Cable Loss The power setting must be no more than the above calculation value. Any higher is a violation of FCC rules. See IMPORTANT warning below. Table 1 Output Power Power Setting

Installation 3.0 Overview Qualified and experienced personnel must carry out the installation, removal or maintenance of all antenna components. The MHX920 complies with FCC part 15 at the modular level for operation in the license-free 902-928 MHz ISM band. This chapter provides guidelines for installing and deploying equipment which incorporates the MHX920 module. 3.1 Estimating the Gain Margin Successful communication between MHX920 modules is dependent on three main factors:
System Gain Path Loss System gain is a calculation in dB describing the performance to be expected between a transmitter-receiver pair. The number can be calculated based on knowledge of the equipment being deployed. The following four factors make up a system gain calculation:
1. Transmitter power (user selectable 0, 20 to 30dBm) 2. Transmitter gain (transmitting antenna gain minus cabling loss between Interference the transmitting antenna and the MHX920 module) 3. Receiver gain (Receiving antenna gain minus cabling loss between the receiving antenna and the module) 4. Receiver sensitivity (Specified as -108dBm on the MHX920 module) In the following illustration, the transmitting antenna has a gain of 6 dB, and the receiving antenna has a gain of 3 dB. The cable loss between the module and the antenna is 2 dB on both the transmitting and receiving side. Cable Loss = 2 dB Cable Loss = 2 dB Antenna Gain = 6 dB Antenna Gain = 3 dB Receiver Sensitivity =
-105 dBm Transmitter 30 dBm Output Power 4 MHX-920 Operating Manual: Chapter 3 Installation Figure 1 Gain Calculation The power level has been set to 30dBm (1W) on the transmitter, and the receiver sensitivity for the MHX920 is -108dBm. System gain would be calculated to be:
30 - 2 + 6 + 3 - 2 + 108 = 143 dB. Base Height (m) Mobile Height
(m) Distance (km) Figure 2 System Deploying When deploying your system, care must be taken to ensure the path loss
(reduction of signal strength from transmitter to receiver in dB) between equipment does not exceed the system gain (140 dB in the above example). It is recommended to design for a gain margin of at least 20 dB to ensure reliable communication. Gain margin is the difference between system gain and path loss. Referring to the same example, suppose the path loss is 100 dB, the gain margin would be 40 dB, which is more than adequate for reliable communication. Path loss is a very complicated calculation which mainly depends on the terrain profile, and the height of the antennas off the ground. The following table provides path loss numbers for varying antenna heights and antenna separation: These numbers are real averages taken from rural environments. They do not apply to urban, non-line-of-sight environments. Table 2 Path Loss Distance

Qualified and experienced personnel must carry out the installation, removal or maintenance of all antenna components. Once the equipment is deployed, you can verify the signal strength by entering into Command Mode and reading Register S123. This register provides the average signal strength in dBm. The minimum strength for communication is roughly -108dBm. For consistent reliable communication, you should try to deploy the equipment such that signal strength exceeds -95dBm. 3.2 Antennas and Cabling This section describes the recommended procedure for installing cabling and antennas for use with the MHX920 module. 3.2.1 Internal Cabling The most common method for installing the module is to run a cable from the modules MCX connector to a reverse TNC bulkhead connector on the chassis of the equipment as shown in Figure 3. This cable can be purchased from Microhard Systems. Reverse TNC Connector RG316 Cable with MCX male connector and Reverse TNC bulkhead connector MCX female connector 0 2 9 X H M Figure 3 Suggested Internal Cabling Cable losses are negligible for the short piece used within the chassis. Additional losses up to 0.5 dB may be present in the MCX and Reverse TNC connections. 6 MHX-920 Operating Manual: Glossary WARNING:
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 23 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter. WARNING:
Direct human contact with the antenna is potentially unhealthy when the MHX920 is generating RF energy. Always ensure that the MHX920 equipment is powered down during installation. WARNING:
Never work on an antenna system when there is lightning in the area. 3.2.2 Installing External Cables, Antennas and Lightning Arrestors Qualified and experienced personnel must carry out the installation, removal or maintenance of all antenna components. Never work on an antenna system when there is lightning in the area. Direct human contact with the antenna is potentially unhealthy when the MHX920 is generating RF energy. Always ensure that the MHX920 equipment is powered down during installation. At all times a distance of 23 cm must be maintained between the antenna and any person when the device is in operation. Surge Arrestors The most effective protection against lightning is to install two lightning
(surge) arrestors, one at the antenna, the other one at the interface with the equipment. The surge arrestor grounding system should be fully interconnected with the transmission tower and power grounding systems to form a single, fully integrated ground circuit. Typically, both ports on surge arrestors are N-female. External Filter Although the MHX920 is capable of filtering out RF noise in most environments, there are circumstances that require external filtering. Paging towers and cellular base stations in close proximity to the MHX920 antenna can desensitize the receiver. Microhard Systems external cavity filter eliminates this problem. The filter has two N-female ports and should be connected in line at the interface to the RF equipment. Weatherproofing Type N and RTNC connectors are not weatherproof. All connectors should be taped with rubber splicing tape (weatherproofing tape), and then coated with a sealant. Cabling The following coax cables are recommended:
Table 3 Cable Loss Cable Loss (dB/100ft) LMR 195 LMR 400 LMR 600 10.7 3.9 2.5 Factors to take into consideration when choosing a cable are:
price;
bend radius limitations (the lower performance cables generally can bend more sharply) performance requirements; and, distance between the equipment and the antenna. MHX-920 Operating Manual:Glossary 7 WARNING:
MAXIMUM ERP FCC and IC Regulations allow up to 36dBm effective radiated power (ERP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 36 dBm with respect to the isotropic radiator. WARNING:
The MHX920 can only be used with any antennas listed in Appendix A. WARNING:
Be careful with dBi vs dBd gains on antenna specifications. Antenna manufactures may not clearly indicate the gain on the antenna if it is dBd or dBi. Note 1dBd = 2.15dBi. When installing the cable, always begin fastening at the top near the antenna connector/surge arrestor. The cable must be supported at the top with a hose clamp or wrap lock, and at 5 ft intervals down the length of the tower. Over-tightening the fasteners will dent the cable and reduce performance. If properly grounded surge arrestors are not installed at both the top and the bottom of the cable, then the cable should be grounded to the tower at these locations using a cable grounding kit. If the tower is non-
conductive, then a separate conductor, physically separate from the cable, should be run down the tower. Antenna Before choosing an antenna, you should have some knowledge of the path loss and the topology of the equipment. If the equipment is in a fixed location and is to communicate with only one other unit also in a fixed location, then a Yagi antenna is suitable. Choose a Yagi with enough gain to ensure adequate gain margin. When deploying the Yagi, point the antenna towards the intended target, ensuring the antenna elements are perpendicular to the ground for vertical polarization. In applications where there are multiple units that you must communicate with or units, which are in motion, you may select an Omni-directional antenna with appropriate gain. See appendix A for a list of approved antennas that can be used with the MHX920 radio modem. If you require another type of antenna please contact Microhard Systems Inc. The MHX920 CANNOT be used with any antenna that does not appear in Appendix A. Microhard Systems Inc. can provide you with approved antennas to ensure FCC and Industry Canada compliance. FCC Regulations allow up to 36dBm effective radiated power (ERP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 36dBm with respect to the isotropic radiator. ERP is calculated as follows:
ERP = Tx Power(dBm) - Cable/Connector Loss(dB) + Ant Gain(dBi) Antenna Gains must be in dBi when calculating the 36dBm ERP limit. 1dBd = 2.15dBi Use the guidelines in the previous section for calculating cable and connector losses. If cabling and connector losses are 2 dB, then the maximum allowable gain of the antenna will be 8 dB. 8 MHX-920 Operating Manual: Glossary Examples:
FCC and Industry Canada Regulations allow up to 36dBm effective radiated power (ERP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 36dBm with respect to the isotropic radiator. Example 1) What is the maximum power the MHX920 can be set to comply with FCC and IC given the following equipment given a Rubber Ducky Ant Gain 2dBi and no cable or connectors in the system?
Max ERP 36dBm Max TX power = ERP Ant Gain(dBi) + Cable/Connector loss (dB) Ant Gain dBi = 2dBi Max TX power = 36dBm 2dBi + 0dB = 34dBm We can set the modem to the maximum power setting of 30dBm. Example 2) What is the maximum power the MHX920 can be set to comply with FCC and IC given the following equipment given a Yagi Ant Gain 12dBd and cable and connector loss of 4.5 dB?
Max ERP 36dBm Max TX power = ERP Ant Gain(dBi) + Cable/Connector loss (dB) Ant Gain dBi = Ant Gain dBd + 2.15 dB Yagi Gain (dBi) = 12 + 2.15 = 14.15dBi Max TX power = 36dBm 14.15dB + 4.5dB = 26.35dBm We must round down Hence Max TX power = 26dBm Example 3) What is the maximum power the MHX920 can be set to comply with FCC and IC given the following equipment given a Omni Ant Gain 6dBd and cable and connector loss of 2.5 dB?
Max ERP 36dBm Max TX power = ERP Ant Gain(dBi) + Cable/Connector loss (dB) Ant Gain dBi = Ant Gain dBd + 2.15 dB Omni Gain (dBi) = 6 + 2.15 = 8.15dBi Max TX power = 36dBm 8.15dB + 2.5dB = 30.35dBm Hence Max TX power = 30dBm MHX-920 Operating Manual:Glossary 9 A.

Span = 0 Hz centered on a hopping channel RBW = 1 MHz VBW = RBW Sweep = as necessary to capture the entire dwell time per hopping channel Detector = peak Trace = max hold If possible, use the marker-delta function to determine the dwell time. If this value varies with different modes of operation (e.g. date rate modulation format, etc.), repeat this test for each variation. The limit is specified in one of the subparagraphs of this Section. Submit this plot(s). An oscilloscope may be used instead of a spectrum analyzer. 20 dB Bandwidth:
Use the spectrum analyzer setting as follows:
Span = approximately 2 to 3 times the 20 dB bandwidth, centered on a hopping channel RBW = 1% of the 20 dB bandwidth VBW = RBW Sweep = auto Detector = peak Trace = max hold The transmitter shall be transmitting at its maximum data rate. Allow the trace to stabilize. Use the marker-to-peak function to set the marker to the peak of the emission. Use the marker-delta function to measure 20 dB down on both sides of the emission.

Refer to FCC @ 1.1310, 2.1091 Spread spectrum transmitters operating under section 15.247 are categorically from routine environmental evaluation to demonstrating RF exposure compliance with respect to MPE and/or SAR limits. These devices are not exempted from compliance (As indicated in Section 15.247(b)(4), these transmitters are required to operate in a manner that ensures that exposure to public users and nearby persons) does not exceed the Commissions RF exposure guidelines (see Section 1.1307 and 2.1093). Unless a device operates at substantially low power levels, with a low gain antenna(s), supporting information is generally needed to establish the various potential operating configurations and exposure conditions of a transmitter and its antenna(s) in order to determine compliance with the RF exposure guidelines. In order to demonstrate compliance with MPE requirements (see Section 2.1091), the following information is typically needed:
1. Calculation that estimates the minimum separation distance (20 cm or more) between an antenna and persons required to satisfy power density limits defined for free space. 2. Antenna installation and device operating instructions for installers (professional/unskilled users), and the parties responsible for ensuring compliance with the RF exposure requirement 3. Any caution statements and/or warning labels that are necessary in order to comply with the exposure limits 4.

Method of Measurements Page 69 FCC ID: NS904P10 Applies to harmonics/spurious that fall in the restricted bands listed in Section 15.205. the maximum permitted average field strength is listed in Section 15.209. A Pre-Amp and highpass filter are used for this measurement. For measurement below 1 GHz, set RBW = 100 KHz, VBW > 100 KHz, SWEEP=AUTO. For measurement above 1 GHz, set RBW = 1 MHz, VBW = 1 MHz (Peak) & VBW = 10 Hz (Average), SWEEP=AUTO. If the emission is pulsed, modified the unit for continuous operation, then use the settings above for measurements, then correct the reading by subtracting the peak-average correction factor derived from the appropriate duty cycle calculation. See Section 15.35(b) and (c). 5.12.3. Please refer to Test Arrangement in Sec. 5.5.3 for details of test setup for emission measurements. Test Arrangement 5.12.4.

METHOD OF MEASUREMENTS - AC MAINS CONDUCTED EMISSIONS AC Mains conducted emissions measurements were performed in accordance with the standard against appropriate Page 103 FCC ID: NS904P10 limits for each detector function. The test was performed in the shielded room, 16'(L) by 16'(W) by 12'(H). The test was performed were made over the frequency range from 450 kHz to 30 MHz to determine the line-to-
ground radio noise voltage which was conducted from the EUT power-input terminals that were directly connected to a public power network. The EUT normally received power from another device that connects to the public utility ac power lines, measurements would be made on that device with the EUT in operation to ensure that the device continues to comply with the appropriate limits while providing the EUT with power. If the EUT operates only from internal or dedicated batteries, with no provisions for connection to the public utility ac power lines, AC Mains conducted measurements are not required. Table-top devices were placed on a platform of nominal size 1 m by 1.5m raised 80 cm above the conducting ground plane. The EUT current-carrying power lead, except the ground (safety) lead, was individually connected through a LISN to the power source. All unused 50-Ohm connectors of the LISN was terminated in 50-ohm when not connected to the measuring instruments. The line cord of the EUT connected to one LISN which was connected to the measuring instrument. Those power cords for the units of devices not under measurement were connected to a separate multiple ac outlet. Drawings and photographs of typically conducted emission test setups were shown in the Test Report. Each current-carrying conductor of the EUT shall be individually tested. The EUT was normally operated with a ground (safety) connection, the EUT was connected to the ground at the LISN through a conductor provided in the lead from the ac power mains to the LISN. The excess length of the power cord was folded back and forth in an 8-shape on a wooden strip with a vertical prong located on the top of the LISN case. The EUT was set-up in its typical configuration and operated in its various modes as described in 3.2 of the test A preliminary scan was made by using spectrum analyzer system with the detector function set to PEAK mode (9 KHz RBW, VBW > RBW), frequency span 450 kHz to 30 MHz. The maximum conducted emission for a given mode of operation was found by using the following step-by-step report. procedure:
Step1. Monitor the frequency range of interest at a fixed EUT azimuth. Step2. Manipulate the system cables and peripheral devices to produce highest amplitude signal relative to the Step3. Step4. limit. Note the amplitude and frequency of the suspect signal. The effects of various modes of operation is examined. This is done by varying equipment operation modes as step 2 is being performed. After completing step 1 through 3, record EUT and peripheral device configuration, mode of operation, cable configuration, signal levels and frequencies for final test. Each highest signal level at the maximized test configuration was zoomed in a small frequency span on the spectrum analyzer's display (the manipulation of cables and peripheral devices and EUT operation modes might have to be repeated to obtain the highest signal level with the spectrum analyzer set to PEAK detector mode 10 KHz RBW and VBW > RBW). The spectrum analyzer was then set to CISPR QUASI-PEAK detector mode (9 KHz RBW, 1 MHz VBW) and AVERAGE detector mode (10 kHz RBW, 1 Hz VBW). The final highest RF signal levels and frequencies were record. Broad-band ac Powerline conducted emissions:- If the EUT exhibits ac Powerline conducted emissions that exceed the limit with the instrument set to the quasi-peak mode, then measurements should be made in the average mode.

EFFECTIVE RADIATED POWER
The following shall be applied to the combination(s) of the radio device and its intended antenna(e).
I f the RF level is user adjustable, all measurements shall be made with the highest power level available to the user for that combination.
The following method of measurement shall apply to both conducted and radiated measurements.
The radiated measurements are performed at the Ultratech Calibrated Open Field Test Site.
The measurement shall be performed using normal operation of the equipment with modulation. Test procedure shall be as follows:
Step 1: Duty Cycle measurements
Using a spectrum analyzer with the frequency span set to 0 Hz and the sweep time set at a suitable value to capture the envelope peaks and the duty cycle of the transmitter output signal;
The duty cycle of the transmitter, x = Tx on / (Tx on + Tx off) with 0<x<1, is measure and recorded in the test report. For the purpose of testing, the equipment shall be operated with a duty cycle that is equal or more than 0.1. Step 2: Calculation of Peak and Average EIRP
The peak output power of the transmitter shall be determined using a wideband, calibrated RF Peak Power Meter with the power sensor with an integration period that exceeds the repetition period of the transmitter by a factor 5 or more. The observed value shall be recorded as P (in dBm);
The Average EIRP. shall be calculated from the above measured power output A, the observed duty cycle x, and the applicable antenna assembly gain G in dBi, according to the formula:
Peak EIRP = P + G Average EIRP = Peak EIRP + 10log(1/x) Figure 1. Step 3: Substitution Method. See Figure 2

The transmitter under test was placed at the specified height on a non-conducting turntable (80 cm height) The dipole test antenna was used and tuned to the transmitter carrier frequency. The spectrum analyzer was tuned to transmitter carrier frequency. The test antenna was lowered or raised from 1 to 4 meters until the maximum signal level was detected. The transmitter was rotated through 360o about a vertical axis until a higher maximum signal was received. The test antenna was lowered or raised again from 1 to 4 meters until a maximum was obtained. This level was recorded. The substitution dipole antenna and the signal generator replaced the transmitter and antenna under test in the same position, and the substitution dipole antenna was placed in vertical polarization. The test dipole antenna was lowered or raised as necessary to ensure that the maximum signal is stilled received.

The level displayed must comply with the limit specified in this Section. Submit this plot 7.4.2. Spurious Emissions (Radiated) The radiated emission measurements were performed at the UltraTechs 3 Meter Open Field Test Site (OFTS) situated in the Town of Oakville, province of Ontario. The Attenuation Characteristics of OFTS have been filed to FCC, Industry Canada, ACA/Austel, NVLap and ITI. Radiated emissions measurements were made using the following test instruments:
1. Calibrated EMCO BiconiLog antenna in the frequency range from 30 MHz to 2000 MHz. 2. Calibrated Emco Horn antennas in the frequency range above 1000 MHz (1GHz - 40 GHz). 3. The test is required for any spurious emission or modulation product that falls in a Restricted Band, as defined in Section 15.205. It must be performed with the highest gain of each type of antenna proposed for use with the EUT. Use the following spectrum analyzer settings:
RBW = 100 kHz for f < 1GHz and RBW = 1 MHz for f > 1 GHz VBW = RBW Sweep = auto Detector function = peak Trace = max hold Follows the guidelines in ANSI C63.4-1992 with respect to maximizing the emission by rotating the EUT, measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the measurement antenna height and polarization, etc.. A pre-amp and highpass filter are required for this test, in order to provide the measuring system with sufficient sensitivity. Allow the trace to stabilize. The peak reading of the emission, after being corrected by the antenna correction factor, cable loss, pre-amp gain, etc. is the peak field strength which comply with the limit specified in Section 15.35(b) Calculation of Field Strength:
The field strength is calculated by adding the calibrated antenna factor and cable factor, and subtracting the Amplifier gain (if any) from the measured reading. The basic equation with a sample calculation is as follows:
FS = RA + AF + CF - AG ULTRATECH GROUP OF LABS 3000 Bristol Circle, Oakville, Ontario, Canada L6H 6G4 Tel. #: 905-829-1570, Fax. #: 905-829-8050, Email: vhk.ultratech@sympatico.ca, Website: http://www.ultratech-labs.com All test results contained in this engineering test report are traceable to National Institute of Standards and Technology (NIST) File #: MCRS-001FCC15C Feb. 30, 2004 FCC PART 15, SUBPART C, SEC. 15.247 - FREQUENCY HOPPING SPREAD SPECTRUM TRANSMITTERS 900 MHz Spread Spectrum OEM Transceiver, Model MHX920 Field Strength Receiver/Analyzer Reading Antenna Factor Cable Attenuation Factor Amplifier Gain Where FS RA AF CF AG

Page 108 FCC ID: NS904P10 Example:
If a receiver reading of 60.0 dBuV is obtained, the antenna factor of 7.0 dB/m and cable factor of 1.0 dB are added, and the amplifier gain of 30 dB is subtracted. The actual field strength will be:
Field Level = 60 + 7.0 + 1.0 - 30 = 38.0 dBuV/m. Field Level = 10(38/20) = 79.43 uV/m. Submit this Test Data Now set the VBW to 10Hz, while maintaining all of the other instrument settings. This peak level, once corrected, must comply with the limit specified in Section 15.209. If the dwell time per channel of the hopping signal is less than 100ms, then the reading obtained may be further adjusted by a duty cycle correction factor, derived from 10log(dwell time/100mS) in an effort to demonstrate compliance with the 15.209. Submit Test Data Maximizing The Radiated Emissions:
The frequencies of emissions was first detected. Then the amplitude of the emissions was measured at the specified measurement distance using required antenna height, polarization, and detector characteristics. During this process, cables and peripheral devices were manipulated within the range of likely configuration. For each mode of operation required to be tested, the frequency spectrum was monitored. Variations in antenna heights (from 1 meter to 4 meters above the ground plane), antenna polarization (horizontal plane and vertical plane), cable placement and peripheral placement were explored to produce the highest amplitude signal relative to the limit.
The maximum radiated emission for a given mode of operation was found by using the following step-by-step procedure:
Step1: Monitor the frequency range of interest at a fixed antenna height and EUT azimuth. Step2: Manipulate the system cables to produce highest amplitude signal relative to the limit. Note the amplitude and frequency of the suspect signal. Step3: Rotate the EUT 360 degrees to maximize the suspected highest amplitude signal. If the signal or another at a different frequency is observed to exceed the previously noted highest amplitude signal by 1 dB or more, go back to the azimuth and repeat Step 2. Otherwise, orient the EUT azimuth to repeat the highest amplitude observation and proceed. Step4: Move the antenna over its full allowable range of travel (1 to 4 meters) to maximize the suspected highest amplitude signal. If the signal or another at a different frequency is observed to exceed the previously noted highest amplitude signal by 1 dB or more, return to Step 2 with the highest amplitude observation and proceed. Step5: Change the polarization of the antenna and repeat Step 2 through 4. Compare the resulting suspected highest amplitude signal with that found for the other polarization. Select and note the higher of the two signals. This signal is termed the highest observed signal with respect to the limit for this EUT operational mode.

This is done by varying the equipment modes as steps 2 through 5 are being performed. Step7: After completing steps 1 through 6, record the final highest emission level, frequency, antenna polarization and detector mode of the measuring instrument. 7.5. ALTERNATIVE TEST PROCEDURES If the antenna conducted tests cannot be performed on this device, radiated tests show compliance with the peak output power limit specified in Section 15.247(b) and the spurious RF conducted emission limit specified in Section 15.247(c) are acceptable. As stated previously, a pre-amp, and, in the later case, a high pass filter, are required for the following measurements:
7.5.1. Peak Power Measurements Calculate the transmitters peak power using the following equation:
E = 30PG/d P = (Ed)2/30G Where:
E: measured maximum fundamental field strength in V/m. Utilizing a RBW, the 20 dB bandwidth of the emission VBW >RBW, peak detector function. Follow the procedures in C63.4-1992 with respect to maximizing the emission
G is numeric gain of the transmitting antenna with reference to an isotropic radiator
D is the distance in meters from which the field strength was measured
P is the distance in meters from which the field strength was measured 7.5.2. Spurious RF conducted emissions The demonstrate compliance with the spurious RF conducted emission requirement of Section 15.247, use the following spectrum analyzer settings:
Span = wide enough to fully capture the emission being measured
RBW = 100 kHz
Sweep = auto
Detector function = peak
Trace = max hold
Measure the field strength of both the fundamental and all spurious emissions with these settings.
Follow the procedures C62-4:1994 with respect to maximizing the emissions. The measured field strength of all spurious emissions must be below the measured field strength of the fundamental emission by the amount specified in Section 15.247. Note that if the emission falls in a Restricted Band, as defined in Section 15.205, the procedure for measuring spurious radiated emissions listed above must be followed ULTRATECH GROUP OF LABS 3000 Bristol Circle, Oakville, Ontario, Canada L6H 6G4 Tel. #: 905-829-1570, Fax. #: 905-829-8050, Email: vhk.ultratech@sympatico.ca, Website: http://www.ultratech-labs.com All test results contained in this engineering test report are traceable to National Institute of Standards and Technology (NIST) File #: MCRS-001FCC15C Feb. 30, 2004
