© 2002 ADTRAN, Inc. TRACER 2210/3202 System ManualFCC Output Power RestrictionsThe FCC does not require licensing to implement this device. However, the FCC has established restrictions regarding maximum output power and the adjustments required when employing directional gain antennas. (Refer to “Setting the Transmitter Power” in Section 2 of this manual). These restrictions are detailed in FCC Part 15.247 (b)(1), (b)(3)(i), and (3)(iii). It is the responsibility of the individuals designing and implementing the radio system to assure compliance with these and any other pertinent FCC Rules and Regulations. This device must be professionally installed.Exposure to Radio Frequency FieldsThe TRACER 2210/3202 is designed to operate at 5.8 GHz with 100 mW maximum transmit power.This level of RF energy is below the Maximum Permissible Exposure (MPE) levels specified in FCC OET 65:97-01. The installation of high gain antenna equipment in the system configuration may create the opportunity for exposure to levels higher than recommended for the general population at a distance less than 15 feet (4.6 meter) from the center of the antenna. The following precautions must be taken during installation of this equipment:• The installed antenna must not be located in a manner that allows exposure of the general population to the direct beam path of the antenna at a distance less than 15 feet (4.6 meters). Installation on towers, masts, or rooftops not accessible to the general population is recommended; or• Mount the antenna in a manner that prevents any personnel from entering the area within 15 feet (4.6 meter) from the front of the antenna.• It is recommended that the installer place radio frequency hazard warnings signs on the barrier that prevents access to the antenna.• Prior to installing the antenna to the RIU output, make sure the power is adjusted to the settings specified in section 2 of this manual.• During antenna installation, be sure that power to the TRACER equipment is turned off in order to prevent any energy presence on the coaxial connector.• During installation and alignment of the antenna, do not stand in front of the antenna assembly.• During installation and alignment of the antenna, do not handle or touch the front of the antenna.These simple precautions must be taken to prevent general population and installation personnel from exposure to RF energy in excess of specified MPE levels.

Section 1, System Description TRACER 2210/3202 System ManualPage 12 of 14 © 2001 ADTRAN, Inc. 61280012L1-1A1. SYSTEM OVERVIEWThe ADTRAN TRACER® 2210/3202 wireless data system provides low-cost point-to-point connectivity between the end user’s Data Terminal Equipment (DTE) for applications such as LAN to LAN bridging and Videoconferencing. TRACER 2210/3202 is capable of achieving distances up to 30 miles. As autho-rized under Part 15.247 of the FCC Rules, the TRACER 2210/3202 operates license-free in the 5.725 to 5.850 GHz industrial, scientific and medical (ISM) band.The TRACER 2210/3202 system is composed of two primary hardware elements: The 2210 Data Interface Unit (DIU) and The 3202 Radio Interface Unit (RIU). The 2210 DIU is contained in a compact plastic housing and supports synchronous data rates from 56 kbps to 1.536 Mbps in 56 or 64 kbps increments. A single V.35 physical interface provides a connection to the end user’s DTE equipment. The weatherproof RIU may be mast mounted up to 700 ft. from the DIU using 24 AWG twisted pair wires. All signaling and power functions between the DIU and RIU are provided over this simple four-wire connection. The TRACER 2210/3202 design locates the radio at the antenna to maximize signal efficiency, while eliminat-ing the requirement of expensive coax to link the DIU and RIU.For configuration and testing, the TRACER 2210/3202 provides the capability to control the remote TRACER 2210/3202 through a separate maintenance channel. The TRACER 2210/3202 has several built-in test capabilities including remote loopback and 511 BERT test patterns. Complete configuration and performance data is available from the front panel keypad and from the two-line by 16-character LCD display on the 2210 data interface. For additional configuration and monitoring options, the TRACER 2210/3202 supports a VT-100 terminal configuration and control mode, which is available through the control port.2.

Section 2, Microwave Path Engineering Basics TRACER 2210/3202 System Manual16 © 2002 ADTRAN, Inc. 61280012L1-1A1. LINE-OF-SITEThe TRACER 2210/3202 system is designed for operation in the 5725 MHz to 5850 MHz unlicensed Industrial, Scientific, and Medical (ISM) frequency band, which is near the middle of what is traditionally referred to as the C-band portion of X-band. Radio wave propagation in this band exhibits microwave characteristics, which are ideally suited for point-to-point, line-of-sight communications. Line-of-sight essentially requires that the transmitting antenna and receiving antenna are able to “see” each other, and that the straight-line path between the two antennas is free of any obstructions, such as buildings, trees, mountains, and, in longer paths, even the curvature of the earth.2. DECIBELSThe received signal power equation is often expressed in a decibel (dB) format, which turns the power multiplication and division operations into addition and subtraction operations. In general, any quantity can be expressed in decibels. If the quantity (x) is a power level, the decibel equivalent is defined asIf the quantity x is referenced to a milliwatt (mW), then the decibel-milliwatt (dBm) is used instead of a generic decibel.Point-to-Point Wireless communication from a single site to another individual site.

RECEIVER POWERThe radio frequency (RF) signal power that is available at the input to the receiving TRACER 2210/3202 system is the next parameter of interest in analyzing a wireless path. Per FCC 15.247 rules, the TRACER 3202 RIU is allowed to output a maximum power level of 100 mW, which is equivalent to 20 dBm. This output signal will be attenuated and distorted by various factors, all of which will degrade the original signal and affect the signal strength and quality as sensed by the receiving unit. A simplified power budget analysis is beneficial to perform after verifying a suitable line-of-sight path to determine if the microwave path is suitable, even for ideal, non-distorted signals.The equation relating received signal power to the other microwave parameters iswhere the variables in the equation are defined asPRreceived power (Watts)PTtransmitted power (100 mW for TRACER 2210/3202)GTtransmit antenna gainGRreceive antenna gainλcarrier wavelength ( c / ƒ ) (meters)dpath distance (meters)Lother losses (RF coaxial cable, etc.)As previously mentioned, the transmitted power is limited for the 5.8 GHz ISM band to a maximum of 20 dBm. The actual transmit and receive antenna gain values are strictly dependent upon the physical characteristics of the antennas installed for each link. Typical gains are between 20 and 30 dB. For example, a 4 foot diameter, flat panel C-band antenna from a popular antenna manufacturer advertises a gain of 23.5 dB. The carrier wavelength is the physical wavelength of the main RF carrier being used for communication, and is usually approximated at the center frequency of the band, which is 5787.5 MHz. This gives a wavelength of 5.18 cm.The path distance is simply the physical distance between the transmit and receive antennas. For the TRACER 2210/3202 these distances can range up to 30 miles. The final parameter L incorporates all other signal power losses in the microwave link, most of which are caused by antenna feed, or coaxial cables used to connect the TRACER 3202 N-type connector to the antenna connector. Since the TRACER 3202 is a mast-mounted device, the antenna feed losses are minimized by requiring only short runs of coaxial cable.PRPTGTGRλ24π()2d2L---------------------------=(watts, W)

PATH LOSSThe expressionwhere fcarrier frequency (Hz)λcarrier wavelength ( c / f ) (meters)dpath distance (meters)cspeed of light, free-space (meters)is called the path loss, and increases rapidly as either path length increases or carrier wavelength decreases (which happens as the carrier frequency increases). So, longer microwave paths will naturally experience more path loss than shorter paths. Likewise, higher frequency microwave communication will experience more path loss than lower frequency microwave communication.Table 1 tabulates path loss values for various path lengths for the TRACER 2210/3202 system. Values not listed in the table can be interpolated from those listed.Table 1.

When using decibel notation, it is necessary that all quantities are individually converted to decibels prior to performing addition and subtraction.When d is expressed in miles and f in GHz, the path loss expression in decibels becomesFigure 1 illustrates a wireless link containing all of the parameters previously discussed.Figure 1. Example Microwave Path with Parameters5. ANTENNA ALIGNMENTWith line-of-sight microwave communications, optimum system performance requires that the transmitting and receiving antennas are properly aligned. This will ensure maximum received signal power at each receiver. Antenna alignment must be achieved in both azimuth (along a horizontal plane) and elevation (along a vertical plane). A received signal strength indicator (RSSI) is used to aid the equipment installer in determining when alignment is maximized, by simply ensuring maximum RSSI. The RSSI indicator for the TRACER 2210/3202 system is provided on the LCD display of the 2210 unit, and is presented as a series of asterisks. More asterisks means more RSSI, which ensures more received signal strength and better link performance.PRPTGTGRL–20 · log10–++ 4πdfc------------2==(dB)LPPTGTGRL–LP–++=(dB)LP96.6 20 log10 d() 20·log+10 f()⋅+= (dB) GTGRd, LPPTPRλLL

Antennas being used with the TRACER 2210/3202 system will have a particular beam shape determined in part by the physical construction and geometry of the antenna. The antenna beam patterns are characterized by a dominant main lobe, which is the preferred lobe to use for point-to-point communications, and several side lobes, as shown in Figure 2. The antenna alignment step to setting up a microwave link is in fact steering the main lobes of both antennas until the main lobe of one transmitter is centered on the receiving element of the receiving antenna.Figure 2. Typical Antenna Beam PatternAntennas are also designed to radiate RF energy efficiently for a specific range of frequencies.

TRACER 2210/3202 System Manual Section 2, Microwave Path Engineering Basics61280012L1-1A © 2002 ADTRAN, Inc. 21Fresnel Zones, Earth Curvature, & Antenna HeightsThe Fresnel zones correspond to regions in the microwave path where reflections of the intended signal occur and combine in both constructive and destructive manners with the main signal, thereby either enhancing or reducing the net power at the receiver.In general, the odd numbered Fresnel zones (1, 3, 5, ...) add constructively at the receiver, while the even numbered Fresnel zones (2, 4, 6, ...) add destructively at the receiver.The first Fresnel zone corresponds to the main lobe, and must be at least 60% free of physical obstructions for the path calculations to be valid. Since the main lobe contains the vast majority of the microwave energy, this zone is typically used to determine proper antenna heights when placing antennas on towers or buildings.The curvature of the Earth becomes a legitimate obstruction for path lengths of 7 miles or greater, and must also be accounted for when determining minimum antenna heights.The aggregate expression for minimum antenna height that incorporates both the 60% first Fresnel zone and the Earth curvature is given bywhere f is in GHz and d is in miles.Table 2 tabulates minimum antenna heights for given path lengths.Table 2.

COAXIAL CABLECoaxial cable will be required to attach the TRACER 3202 mast unit to the antenna. The length of the cable will vary from a few feet to several feet, depending upon your application and the proximity of the TRACER 3202 to the antenna. Since the data/power cable attaching the TRACER 2210 indoor unit to the TRACER 3202 mast unit can operate at lengths of up to 700 feet, it is recommended that this cable absorb as much of the length between the 2210 unit and the antenna as possible. This will also decrease coaxial cable losses in the overall power budget for the link, which was described previously.Various grades of coaxial cable will work sufficiently well for connecting the TRACER 3202 unit to the antenna. A low-loss coaxial cable is suggested to minimize cable losses. One end of the cable will require an N-type male connector (plug) to mate with the TRACER 3202 unit. The other end of the coax will require a connector compatible with the antenna chosen for the installation, which is usually also an N-type male connector (plug). Additionally, it is recommended that both connectors on the coaxial cable be weatherproofed from the elements to prevent corrosion and electrical shorting.Table 3 gives typical loss figures for some of the more common coaxial cable types, per footIn certain areas where lightning strikes are frequent, a lightning arrestor can be installed directly on the antenna. This will help protect the RF electronics in the downstream path from damaging voltages and currents, including the TRACER 3202 unit.7. RECEIVER SENSITIVITYReceiver sensitivity is a value expressed in decibels referenced to one milliwatt (dBm) that corresponds to the minimum amount of signal power needed at the receiver to achieve a given bit error rate (BER). Receiver sensitivity is usually a negative number of decibels, and as such smaller receiver sensitivity is better for a given BER. Several factors affect receiver sensitivity, including the data bandwidth of the wireless link, and the amount of additional signal degradation introduced in the receiver electronics. The receiver sensitivity of the TRACER 3202 is -86 dBm at 10-6 BER.8. FADE MARGINFade margin is a value indicating the amount of extra signal power available to the receiver to operate at a maximum bit error rate (BER). Higher levels of fade margin are better, and will protect the viability of the microwave link against signal fading. Fade margin is simply the difference between the available signal power at the receiver and the receiver sensitivity, discussed previously:Table 3.

PATH AVAILABILITYThe path availability of a wireless link is a metric that expresses the fractional amount of time a link is available over some fixed amount of time, and depends on several factors. Path availability is expressed aswhere the parameters areaterrain factorbclimate factorfcarrier frequency (GHz)dpath length (miles)Ffade margin (dB)The terrain factor is a quantity that compensates the link availability for different types of terrain. Generally speaking, the more smooth an area's terrain is, the less availability a wireless link running over that terrain will have, primarily due to multipath reflections. In contrast, secondary microwave signals will be randomly dispersed over rough terrain, and will not interfere with the main signal lobe as badly as in the smooth terrain case. The terrain factor values normally used are listed below:The climate factor is a quantity that compensates the link availability for different types of climates (weather). In general, microwave links operating in areas with high humidity will have less availability than those in arid areas, primarily because water is a dispersive mechanism to microwave energy, and causes the main signal lobe to refract and disperse away from the receiver location. The climate factor values normally used are listed below.Terrain Terrain Factor DescriptionSmooth 4 water, flat desertAverage 1 moderate roughnessMountainous 1/4 very rough, mountainousClimate Climate Factor DescriptionVery Dry 1/8 desert regionsTemperate 1/4 mainland, interior regionHumid 1/2 humid and coastal regionsA1 2.5 10 6–×()abfd310 F10⁄–()–[]100%×=(dB)$

Section 4, Network Turnup Procedure TRACER 2210/3202 System Manual34 © 2002 ADTRAN, Inc. 61280012L1-1A5. CHANNEL SELECTIONThe FCC has allocated 125 MHz of spectrum in the band in which the TRACER 2210/3202 operates. Figure 2 illustrates the bandwidth division. Figure 2. Bandwidth DivisionTo designate the utilization of the ISM bandwidth, there are four different channel plans, labeled A1, B1, A2 and B2. The letter of each channel plan setting is preset by the factory and refers to the physical configuration of the diplexer filter inside the environmental housing. The second portion or letter of the channel plan refers to the receive and transmit oscillator frequencies in the radio. Numbering the lobes in Figure 2 from left to right, a channel plan of A1 or B1 refers to transmitting and receiving on the first and third lobes. Likewise a channel plan of A2 or B2 refers to the transmitting and receiving of the second and fourth lobes of Figure 2. There are two rules for successful 3202 configuration.1. The letter of the channel plan must be different on both ends.2. The frequency number must match. An A1 Radio must have a B1 Radio on the other end and a B2 Radio must have an A2 Radio on the other end.6.

Section 5, User Interface Guide TRACER 2210/3202 System Manual42 © 2002 ADTRAN, Inc. 61280012L1-1ACONFIG > V.35 > V.35 TX CLKControls the clock used by the TRACER 2210 DIU to accept the transmit (TX) data from the DTE. Most applications will allow for this to be set to INTERNAL. If the cable between the TRACER 2210 DIU and the DTE equipment is long (causing a phase shift in the data) the clock can be selected as INT-INV (Internal/Inverted). This switches the phase of the clock which should compensate for a long cable. The AUTO setting will allow the TRACER 2210 DIU to automatically detect the delay from the DTE device to the V.35 interface of the DIU and set the proper phase of the clock. This feature will automatically select between the INTERNAL and INT-INV settings. If the DTE provides a clock with TX data, the clock selection should be set to EXTERNAL. When set to EXTERNAL, the TRACER 2210 DIU will require an externally supplied clock to accept TX dataChoices: AUTO, INT-INV, EXTERNAL, INTERNALCONFIG > V.35 > DATAUsed to control the inverting of the DTE data.

Section 4, Trouble Shooting Guide TRACER 2210/3202 System Manual48 © 2001 ADTRAN, Inc. 61280012L1-1A1. OVERVIEWIn general, system configuration errors fall into 1 of 4 categories: (1) 2210-to-3202 cabling errors(2) Invalid 2210 settings(3) DTE configuration errors(4) RF errors2. 2210-TO-3202 CABLING ERRORSEnsure that the electrical connection between the cable splices and the terminal block plug on the 2210 is correct, using an ohmmeter. If all 4 conductors are intact, ensure that the pin-out is correct for each connector, i.e. pin 1 on the terminal block is attached to conductor 1 on the spliced cable, etc.3. INVALID 2210 SETTINGSSeveral V.35 interface options are available for the TRACER 2210 for connecting to DTE equipment (eg. router, bridge), and its interface with the radio link. Timing SettingsTiming settings determine how the TRACER 2210 synchronizes itself to external equipment, including the DTE hardware attached to the V.35 port, and the remote 2210 unit on the opposite end of the radio link. A fully synchronized and operational TRACER 2210/3202 system requires that one and only one piece of communications equipment control timing throughout the system. The TRACER 2210 has been flexibly designed so that either the 2210 or the attached DTE equipment can mandate timing.Most DTE equipment will expect timing to originate from the 2210 unit. In these common applications the factory default, or AUTO, settings stored in the 2210 will synchronize the DTE and TRACER 2210/3202 circuits together. For those DTE devices that require self-regulated system timing, the TRACER 2210 timing settings will need to be changed via the 2210 menu.V.35 SettingsInterface-related errors may also occur if the number of 56/64 kHz sub-channels is incompatible with the DTE hardware. To remedy this problem, set the 2210 V.35 rate within the limits of the DTE bandwidth.There are two distinct clock circuits in the 2210. One clock circuit interfaces with the V.35 port, and the other clock circuit interfaces with the radio channel (network). The V.35 clock setting determines whether the V.35 port accepts (sinks) or provides (sources) the clock used to synchronize data transmission between the DTE unit and the 2210. The 2210 internal clock setting determines whether the internal 2210 oscillator, DTE received clock, or radio interface clock is used as the internal clock source for the 2210 unit. In most applications, the default (AUTO) timing settings for these two clocks will be correct.The TRACER 2210 is factory-configured to network timing, and so acts as standard DCE hardware when connected via a V.35 cable to DTE hardware. When using the 2210 in non-standard applications, please consult both the DTE hardware user’s manual and TRACER 2210 user’s manual for proper settings information.

TRACER 2210/3202 System Manual Section 4, Trouble Shooting Guide61280012L1-1A © 2001 ADTRAN, Inc. 494. INVALID DTE SETTINGSIt may be necessary to change certain options on the DTE hardware. Please consult the user’s manual for your particular DTE hardware to ensure proper setup.5. RF ERRORSRF errors can range anywhere from a non-viable microwave path to loose RF connectors. Non-viable path conditions could be caused by physical obstructions such as buildings, mountainous terrain, trees, etc., as well as other physical limitations such as excessive path distances and in-band RF interference. These types of errors are remedied by performing a detailed line-of-sight microwave path study to determine whether or not a microwave link is feasible for the terrain and environment under consideration. If after performing a microwave path study the system is still not operational, ensure that the antennas are properly aligned. Note that alignment must be achieved in both elevation and azimuth for optimal link performance. The TRACER 2210 can be used to aid in antenna alignment by looking at the RSSI submenu. Optimal antenna alignment will correspond to the maximum number of RSSI asterisks (or bars) on the 2210 RSSI display.6. LOOPBACK OPTIONSThe TRACER 2210/3202 has several data path loopback options available to assist in piece-wise verification of data path integrity throughout the circuit. Each loopback option can be turned on/off from the keypad menu on the 2210 unit. Enter the following menu selection to access the Loopback submenu.4) TEST →→→→ 1) LOOPBACKSThe available loopback points are RADIO CABLE, 2210 TO DTE, 2210 TO RADIO, and FAR 2210. (Figure 1 on page 49) shows the loopback locations and directions graphically.Figure 1. TRACER 2210/3202 Loopback Diagram1324

Section 4, Trouble Shooting Guide TRACER 2210/3202 System Manual50 © 2001 ADTRAN, Inc. 61280012L1-1A2210 to DTE (V.35) LoopbackPerforms a loopback at the V.35 DTE data interface. All received V.35 data is looped back in the transmit direction toward the DTE equipment. This loopback is useful for diagnosing DTE device configuration and setup.2210-to-Radio LoopbackPerforms a loopback at the line interface inside the TRACER 2210 unit directed back toward the host 3202 unit. This loopback is useful for diagnosing problems in the TRACER 3202 radio units.Radio Cable LoopbackPerforms a loopback at the line interface inside the TRACER 3202 radio unit directed back toward the host 2210 unit. This loopback is useful for diagnosing the radio cable connecting the 2210 and 3202 units, in addition to differentiating between radio link errors on the remote or local ends of the link.Far 2210 LoopbackEffectively performs a 2210-to-Radio loopback on the remote TRACER 2210 unit. This loopback exercises the majority of the system circuitry and is useful for verifying end-to-end operation from a single location.7. TEST PATTERNSThe TRACER 2210/3202 has several data test patterns available to test bit integrity throughout the system. Typically these patterns are used in conjunction with a loopback option to determine which system device is demonstrating faulty behavior. The available patterns are a 511 pattern, a QRSS pattern, and a 1-in-8 pattern (1:8). Additionally, most third party test equipment will recognize and can operate with these three standard patterns.1-in-8 PatternThe 1-in-8 (1:8) pattern is simply a repetition of the binary data sequence 10000000. The 1:8 pattern is useful when needing to identify a regular data stream through the system.511 PatternThe 511 pattern is a pseudo-random data sequence that repeats every 511 bits. It is a relatively short periodic sequence that can be used to simulate live data. The 511 pattern is generated by a length-9 shift register with the logical exclusive-or of registers 9 and 5 being fed back to register 1.QRSS PatternThe QRSS pattern, or quasi-random signal sequence, is a test sequence designed to simulate live data traffic. It is based on a length-20 shift register with the logical exclusive-or of registers 17 and 20 being fed back to register 1. The shift register contents are monitored for runs of 14 consecutive zeros, in which case the QRSS generator will force the output to logic-1 to proceed the run of zeros. The QRSS pattern is designed to have a 1-to-0 ratio of 1:1. .... 0 1 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 1 0 0 ....

$TRACER 2210/3202 System Manual Section 4, Trouble Shooting Guide61280012L1-1A © 2001 ADTRAN, Inc. 518. STEP-BY-STEP TROUBLESHOOTINGThe logical troubleshooting flow presented in this section can be used to set up your TRACER 2210/3202 system, and also to diagnose a previously installed system. Please contact Adtran Technical support at any stage during installation and/or troubleshooting if you require assistance.9. INSTALLING/TROUBLESHOOTING THE TRACER HARDWARE1. Perform a detailed path profile for each TRACER 2210/3202 microwave link. A thorough path study can be used to estimate signal power budgets, fade margins at each receiver, identity potential line-of-site obstacles, properly size antenna dishes, and determine minimum antenna dish heights above the earth.2. Setup all of the TRACER hardware on a work bench. This includes both 2210 units, both 3202 units, and RF attenuators or antennas. It is also recommended that the actual cables to be used in the permanent installation be used in the work bench setup. A rigorous work bench "simulation" of the link will help you alleviate and avoid time-consuming errors.3. After applying power to the 2210 units, examine the CABLE light on the front panel of each 2210. If this light is illuminated (green), then the 2210 is delivering power and data to the 3202 unit. If the CABLE light is not illuminated, then the 3202 is not connected properly to the 2210 unit. Normally this means that there is a physical problem with the cable attaching the 2210 to the 3202. Any of several cabling errors could be present, including disconnected cable splices, severed wire, or improper conductor ordering of the 4-wire cable to the back of the 2210 unit.4. Resolve all 2210/3202 cabling errors using an ohmmeter before proceeding.5. Command a RADIO CABLE loopback on each individual 2210/3202 pair, and run either a 511 or QRSS test pattern to verify proper attachment of the 2210/3202 units. You should not see any pattern errors during the test. Clear all test patterns after verification is finished.6. Examine the PLAN A, PLAN B, and CHAN lights on the front panel of each 2210 unit. These LEDs indicate the frequency plan and frequency channel for each 2210/3202 unit. The factory default setting for the frequency channel is channel 1, while the frequency plan will be prefixed to plan A for one 3202 unit, and plan B for the other 3202 unit. The color of the frequency channel (CHAN) LED on both 2210 units should be the same. The frequency plan (PLAN A, PLAN B) LED should be the opposite on both 2210 units. Unless you have verified that changing the frequency channel is necessary for a particular link, there is no need to manually change the channel setting on either unit. Possible conditions that could benefit by changing the frequency channel include co-channel interference from a third party, or co-location applications. 7. Attach the RF coaxial cables to be used in the permanent installation to the N-type connectors on the base of the 3202 unit. Attach the other end of the coaxial cable(s) to an RF power meter or spectrum analyzer if either is available. The power measured by the meter/analyzer will be the RF power available at the input of the antenna. The 3202 unit is programmed at the factory to output approximately 100 mW (20 dBm) of 5.8 GHz RF power. The actual power level measured by the meter/analyzer will be less than 100 mW due to RF losses through the coaxial cable, and is a function of cable type and length of cable being used. In any event, the power level at the output of the coaxial cable should be a significant fraction of 100 mW. A power meter/analyzer reading that is not on the order of at least tens-of-milliwatts could be an indication of any combination of either unsuitable RF, faulty, or unreasonably long coaxial cable.$
