TRACER 5045 System Manual Section 2 Microwave Path Engineering Basics612805045L1-1A © 2003 ADTRAN, Inc. 151. LINE-OF-SITEThe TRACER 5045 system is designed for operation in the license-free 5.725 GHz to 5.850 GHz industrial, scientific and medical (ISM) 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 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 obstructions, such as buildings, trees, mountains, and, in longer paths, even the curvature of the earth. In addition, for maximum signal strength the area around the visual line-of-sight where microwave signals reflect (Fresnel zone) must also be free of obstructions. Fresnel zones are discussed in more detail on page 21.Terminology2. DECIBELSUnderstanding the decibel (dB) format is key when discussing microwave path engineering because the received signal power is often expressed in decibel format. In general, any quantity can be expressed in decibels. If the quantity x is a power level (in Watts), 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.Using the decibel format simplifies power calculations by reducing multiplication and division operations into addition and subtraction operations.3. CALCULATING THE FADE MARGINThe fade margin (F ) is a value indicating the amount of extra signal power available to the receiver to operate at a maximum bit error rate (BER). Fade margin is simply the difference between the available signal power at the receiver (PR ) and the receiver sensitivity (Psens ). Point-to-Point Wireless communication from a single site to another individual site. Contrast with point-to-multipoint.Line-of-Sight An unobstructed, direct path exists between the transmitting and the receiving antennas.It is imperative to determine if the proposed microwave path is suitable (at a minimum) for ideal, nondistorted signals before attempting installation.xdB 10 log10 x()⋅=(dB)xdBm 10 log10x1mW-------------⋅=(dBm)FPRPsens–=(dB)
Section 2 Microwave Path Engineering Basics TRACER 5045 System Manual 16 © 2003 ADTRAN, Inc. 612805045L1-1AHigher levels of fade margin indicate stronger protection against signal fading and a more reliable link. For most applications, 20 to 30 dB of fade margin should ensure a reliable link. The following sections further discuss the necessary power calculations and their components.4. RECEIVER POWERThe viability of a particular microwave path is determined by the power of the transmitted microwave signal, the transmit and receive antenna gain, distance, and accumulated system losses (such as RF coaxial cable losses and path loss).The equation relating received signal power to the other microwave parameters isor (in decibel notation)where the variables in the equation are defined asPRreceived power (Watts)PTtransmitted power (100 mW (max) for TRACER 5045 - adjustable)GTtransmit antenna gainGRreceive antenna gainλcarrier wavelength (meters)dpath distance (meters)Lother losses (RF coaxial cable, etc.)LPpath loss (dB)Figure 1 on page 17 illustrates a wireless link configuration containing all the parameters necessary for the power budget analysis.When using decibel notation, all quantities must be individually converted to decibels prior to performing addition and subtraction.PRPTGTGRλ24π()2d2L------------------------------=(Watts, W)(decibels referenced to a Watt, dBW)PR = PT + GT + GR - L - LP
TRACER 5045 System Manual Section 2 Microwave Path Engineering Basics612805045L1-1A © 2003 ADTRAN, Inc. 17Figure 1. Example Microwave Path with ParametersThe following sections further discuss the power budget analysis and its components.Antenna GainActual transmit and receive antenna gain values depend strictly upon the physical characteristics of the antennas installed for each link. In other words, the size of the dish determines the antenna gain. Using a parabolic dish antenna results in the best performance. Antenna gains are specified in terms of decibels of gain referenced to an isotropic source (dBi). An isotropic source is a hypothetical antenna having equal radiation in all directions. Typical antenna gains are listed in Table 1; however, dish manufacturers can provide gains for specific types of antennas.Transmitted Power (PT)The FCC specifies the maximum transmitter power used for antennae of a given gain. FCC Rules Part 15, Subpart 247 allow for a maximum power of 1 Watt (30 dBm) into antennae of a gain less than or equal to 6 dBi. Since the TRACER 5045 maximum transmit power is 100 milliwatts, there is no reduction in transmitter output power required for antennae gains greater than 6 dBi.Table 1.

Section 2 Microwave Path Engineering Basics TRACER 5045 System Manual 18 © 2003 ADTRAN, Inc. 612805045L1-1ACarrier Wavelength (λ)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 for the TRACER 5045). The carrier wavelength calculations follow:λ = c / f (meters)where c = speed of light (in meters)f = frequency (in Hz)resulting in the following carrier wavelength:λ = 3.00 x 10¯8 / 5787.5 x 10 5 = 0.0518 m or 5.18 cmPath Distance (d)The path distance is simply the physical distance between the transmit and receive antennas. For the TRACER 5045, these distances can range up to 30 miles. System Losses (L)System losses are defined by RF coaxial cable loss, connector losses, and losses added from any additional lightning protection devices for the power budget analysis. Coaxial cable is required to attach the TRACER 5045 to the antenna. The length of the cable varies from a few feet to several feet, depending upon your application and the proximity of the TRACER 5045 to the antenna. Various grades of coaxial cable will work sufficiently well for connecting the TRACER 5045 unit to the antenna. A low-loss coaxial cable will minimize cable losses.One end of the coaxial cable requires an N-type male connector (plug) to mate with the TRACER 5045 unit. The other end of the coaxial cable requires a connector compatible with the antenna chosen for the installation (usually an N-type male connector). Additionally, ADTRAN recommends that the outdoor connector on the coaxial cable be weatherproofed to prevent corrosion and electrical shorting.In areas where lightning strikes are frequent, a lightning arrestor should be installed directly on the antenna coaxial cable. Installing lightning arrestors helps protect the RF electronics in the downstream path from damaging voltages and currents (including the TRACER 5045 unit).
TRACER 5045 System Manual Section 2 Microwave Path Engineering Basics612805045L1-1A © 2003 ADTRAN, Inc. 19Table 2 gives typical loss figures for some of the more common coaxial cable types (per 100 feet).Path Loss (LP)Path loss is the estimated attenuation between the transmit and receive antennas caused by signal separation and scattering. The path loss is considered basic transmission loss over the microwave link. The following expression calculates path loss:where fcarrier frequency (Hz)λcarrier wavelength (c / f) (meters)dpath distance (meters)cspeed of light, free-space (meters)orwhere d is expressed in miles and f in GHzPath loss, as shown here, increases rapidly as either the path length increases or the carrier wavelength decreases (which happens as the carrier frequency increases). Therefore, longer microwave paths naturally experience more path loss than shorter paths. Likewise, higher frequency microwave communication experiences more path loss than lower frequency microwave communication.Table 2.

Values not listed in the table can be interpolated from those listed.5. 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 smaller receiver sensitivity (higher quantity negative number) 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 5045 is -90 dBm at 10-6 BER.6. ANTENNA INFORMATIONThe overall wireless system is directly affected by the antenna selection and installation. The following sections discuss several factors concerning antenna selection and installation.Antenna AlignmentWith line-of-sight microwave communications, optimum system performance requires that the transmitting and receiving antennas are properly aligned. This ensures 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) aids the equipment installer in determining when alignment is maximized by simply ensuring maximum RSSI. Table 3.

TRACER 5045 System Manual Section 2 Microwave Path Engineering Basics612805045L1-1A © 2003 ADTRAN, Inc. 21TRACER RSSI Test PointsThe RSSI indicator for the TRACER 5045 system is provided through the VT100 terminal menus accessed through the RS-232 interface, and it is presented as a series of bars indicating signal strength. More bars means more RSSI, which ensures more received signal strength and better link performance.If the local system has acquired a useful signal from the remote system, then the remote TRACER 5045 RSSI can be viewed from the local TRACER 5045 VT100 terminal menu interface.An RSSI test point, located on the front panel, represents the voltage (relative to the GND test point) of a relative signal level of receive strength from the far end. The voltage at this test point can vary from approximatly 0 to greater than 4 Volts DC, with 0 Volts corresponding to no signal and 4 Volts or better to full signal strength.Antenna Beam PatternsDirectly related to the subject of antenna alignment is the topic of antenna beam patterns. Antennas used with the TRACER 5045 system 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 1. When setting up a microwave link, antenna alignment is nothing more than 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. Please consult the data sheet for your particular antenna make and model to ensure that it is specified to operate in the 5725 MHz to 5850 MHz frequency band for the TRACER 5045 system.Fresnel Zones, Earth Curvature, & Antenna HeightsFresnel 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.main lobeside lobes
Section 2 Microwave Path Engineering Basics TRACER 5045 System Manual 22 © 2003 ADTRAN, Inc. 612805045L1-1AThe first Fresnel zone corresponds to the main lobe, 60% of which must be 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’s curvature is given bywhere f is in GHz and d is in miles.Table 4 tabulates minimum antenna heights for given path lengths.Table 4.

OTHER CONSIDERATIONSPath 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)Terrain Factor (a)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:Climate Factor (b)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 4water, flat desertAverage 1moderate roughnessMountainous 1/4 very rough, mountainousClimate Climate Factor DescriptionVery Dry 1/8 desert regionsTemperate 1/4 mainland, interior regionHumid 1/2 humid and coastal regionsA12.5106–×()abfd310 F10⁄–()–[]100%×=(%)

EQUIPMENT DIMENSIONSThe TRACER 5045 unit is 19” W, 10.5” D, and 1.75” H, weighs 7 lbs, and can be used in rack-mount configurations.2. POWER REQUIREMENTSThe TRACER 5045 system has a maximum power consumption of XXXX W and a maximum current draw of XXXX A (at 21 VDC).3. REVIEWING THE FRONT PANEL DESIGNThe front panel contains RSSI monitoring interface, a GND interface for reference with RSSI, and status LEDs to provide visual information about the TRACER 5045 system. Figure 1 identifies the various bantam interfaces and the LEDs.Figure 1. TRACER 5045 Front Panel LayoutRSSI Monitoring InterfaceThe RSSI voltage is a function of the signal strength at the receiver and is used to measure the received signal strength. RSSI varies approximately from 0 to greater than 4 Volts (V), with 0V corresponding to a weaker received signal and 4V or better corresponding to a stronger received signal.Front Panel LEDsWith the TRACER 5045 powered-on, the front panel LEDs provide visual information about the status of the TRACER 5045 system. Table 1 provides a brief description of the front panel features, and Table 2 on page 27 provides detailed information about the LEDs.The voltage level present at the RSSI test point represents only a relative signal level of receive strength from the far end. No direct correlation can be made between RSSI voltage levels and actual receive levels in dBm. This test point is provided to assess relative signal level for alignment of antennas.Table 1.

TRACER 5045 System Manual Section 3 Engineering Guidelines612805045L1-1A © 2003 ADTRAN, Inc. 29RS-232 Connection (Modem Use)Modem controls, discussed in Section 5, User Interface Guide, enable or disable modem control through the RS-232 interface. When this option is enabled from a standard terminal connection, all RS-232 communications cease until a modem with a null modem adapter is attached between the TRACER 5045 and the data modem. Configure the data modem for AUTO ANSWER and 9600 BPS. When the user connects via the modem to the TRACER 5045 unit, communications via the RS-232 port resume. If a user accidentally enables modem control from a terminal and disrupts the RS-232 communication, pressing <Ctrl + Z> three times will temporarily disable the modem control option (until the system is reset) and will access the system configuration to disable modem control.The TRACER 5045 must be interfaced to a modem via an RS-232 null modem adapter or cable. The null modem converts Clear To Send (CTS) and Data Set Ready (DSR) into Ready To Send (RTS) and Data Terminal Ready (DTR), respectively. These signals indicate (to most modems) that a valid DTE terminal device is present. The null modem interface must route Carrier Detect (CD) on pin 8 directly from the modem. When using the RS-232 interface for modem control, the modem must source CD only when actually connected to a carrier.When MODEM CONNECTION is selected in the menu system, the TRACER 5045 will de-assert DTR and DSR for a time greater than 20 msec. The null modem consequently drops DTR and RTS at the modem interface, signaling the modem to hang up the line. If password functionality is enabled in the TRACER Table 3.

TRACER 5045 System Manual Section 3 Engineering Guidelines612805045L1-1A © 2003 ADTRAN, Inc. 31Alarm Contacts (Plug-In Terminal Block)Normally open (NO) and normally closed (NC) alarm contacts are provided on the rear panel of the TRACER 5045 system. In normal operation, the NC contact is electrically connected to the common contact (COM) and the NO contact is isolated. During an alarm condition, the NC contact becomes isolated and the NO is electrically connected to COM. This allows alarm conditions to be reported to external alarm monitoring systems.DC Power Connection (Plug-In Terminal Block)The TRACER 5045 can operate from a supply between 21 and 60 VDC, with either polarity referenced to ground, and consumes less than XXXX Watts (W). Power supplies should be able to provide up to XXXX W at the selected voltage. Current required (in Amps) is determined by dividing the power consumed (in Watts) by the applied voltage (in Volts). For example, at 48 V, TRACER 5045 would draw approximately XXXX A (XXXX W/48 V).FuseThe fuse holder, accessible from the rear panel of the TRACER 5045, accepts a generic 1 A, 250 V, 2-inch slow-blo fuse.Antenna Interface (N-Type connector)The ANTENNA interface (N-Type connector) connects to the customer-supplied antenna using standard antenna feedline cable. When determining the cable specifications for your application, refer to Section 2, Microwave Path Engineering Basics (System Losses (L) on page 18) for a discussion on cable length and loss factors.5.

TRACER 5045 System Manual Section 4, Network Turnup Procedure612805045L1-1A © 2003 ADTRAN, Inc. 374. CHANNEL SELECTIONThe FCC has allocated 125 MHz of spectrum in the 5.8 GHz band where the TRACER 5045 operates. Figure 1 illustrates the bandwidth division. Figure 1. 5.8 GHz Bandwidth DivisionTo designate the utilization of the ISM bandwidth, there are two different channel plans, labeled A and B. 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 bandplans must be the same for the local and remote TRACER 5045. For example, the transmitter at one end of the link will transmit in the lower portion of the spectrum and receive in the upper portion. Consequently, the receiver at the other end should receive in the lower portion and transmit in the upper portion.The letter of the channel plan (A or B) must be different on both ends. Shipment of a link will consist of one Plan A and Plan B unit.5. GROUNDING INSTRUCTIONSThe following provides grounding instruction information from the Underwriters’ Laboratory UL 60950 Standard for Safety of Information Technology Equipment Including Electrical Business Equipment, of December, 2000.An equipment grounding conductor that is not smaller in size than the ungrounded branch-circuit supply conductors is to be installed as part of the circuit that supplies the product or system.

Section 6 Troubleshooting Guide TRACER 5045 System Manual 52 © 2003 ADTRAN, Inc. 612805045L1-1A1. OVERVIEWThis troubleshooting guide provides recommended actions for various conditions of the TRACER 5045 system. The status LEDs (located on the front panel of the unit) provide information to help determine the necessary troubleshooting action. Recommended actions for resolving possible status LED indicators are contained in this guide.2. LED INDICATORSPWR LEDIf the PWR LED is not ON and solid green, it is an indicator that the TRACER 5045 is not receiving adequate DC power. Recommended Actions:1. Verify that the power source is delivering between 21 and 60 VDC.2. Check the polarity of the power connection (referenced to ground) of both the TRACER 5045 unit and the power source.3. Check the internal fuse. The fuse is accessed from the rear panel of the unit. If this fuse is open, replace with a 1 A, 250 V (2-inch) slow-blo fuse.TST LEDThe TST LED will remain ON (solid amber) during power-up to indicate a self-test is in progress. If the TST LED is blinking or remains ON after 10 seconds, this indicates that the TRACER 5045 unit has failed the self-test. This is an internal failure, and ADTRAN technical support should be contacted.RF DOWN LEDIf the RF DOWN LED is ON (solid red), it is an indicator that there is a problem with the RF link to the TRACER 5045.Recommended Actions:1. Check the RF coaxial cable connection.2. Measure the RSSI voltage. If the signal is acceptable (> 2.0 VDC at RSSI test point), go to Step 6.3. Verify that one end of the link is configured as Plan A and the other end as Plan B.4. Verify that the antenna polarization is the same at both ends of the RF signal transmit and receive path.5. Verify the RF signal path is clear.6. Check for possible interference at both ends of the link. If necessary, change polarization and/or bandplans at both ends.7. Check the integrity of the lightning arrestors.
TRACER 5045 System Manual Section 6 Troubleshooting Guide612805045L1-1A © 2003 ADTRAN, Inc. 53RF LOW LEDIf the RF LOW LED is ON (solid red), it is an indicator that the received signal is within 10 dB (approximately) of the minimum operable signal. This condition is typically indicative of a path problem.Recommended Actions:1. Verify the far-end transmitter power setting is the value that the link planning budget allows.2. Check all coaxial cable connectors for solid connections. Check for water and corrosion around any of the connectors. If water is apparent in the coaxial connectors, replace the coaxial cable and the connectors, making sure to properly weatherproof the replacements.3. Verify the RF signal path by verifying the antenna alignment.4. Check the integrity of the cable plant.5. Check the integrity of lightning arrestors.LAN LEDsIf the LAN LED is OFF, it is an indication that the TRACER 5045 does not detect an active ethernet link on the particular 10/100BaseT/TX interface. Recommended Actions:1. Check all ethernet cable connections to verify they are properly plugged in (making sure the tab on the connector snaps into place). 2. Connect the 10/100BaseT/TX interface to a “known good” ethernet port to verify the TRACER port is functioning properly.3. Try another ethernet cable.3. RF ERRORSRF errors can range anywhere from a nonviable microwave path to loose RF connectors.Nonviable path conditions could be caused by physical obstructions such as buildings, moutainous 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-site microwave path study to determine whether 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 5045 can be used to aid in antenna alignment by looking at the RX POWER “fuel gauge” on the System Status or System Configuration menu pages. Optimal antenna alignment will correspond to the maximum number of RSSI bars on the TRACER 5045 terminal display.4. STEP-BY-STEP TROUBLESHOOTINGThe logical troubleshooting flow presented in this section can be used to set up your TRACER 5045 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.
Section 6 Troubleshooting Guide TRACER 5045 System Manual 54 © 2003 ADTRAN, Inc. 612805045L1-1A5. INSTALLING/TROUBLESHOOTING THE TRACER HARDWARE1. Perform a detailed path profile and link budget for each TRACER 5045 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 workbench. ADTRAN recommends that the actual cables used in the permanent installation be used in the workbench setup. A rigorous workbench “simulation” of the link will help alleviate and avoid time-consuming errors.3. Examine the PLAN A and PLAN B LEDs on the front panel of each unit. These LEDs indicate the frequency plan for each TRACER 5045 unit. The frequency plan (Plan A, Plan B) LED should be the opposite on the TRACER 5045 units. 4. Attach the RF coaxial cables to be used in the permanent installation to the N-type connectors on the back of the TRACER 5045 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 TRACER 5045 unit is programmed at the factory to output approximately 100 mW (20 dBm) of 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 the cable type and length 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.5. Resolve all RF coaxial cabling errors before proceeding.6. Attach the RF coaxial cables to a high-quality attenuator, if possible. If you do not have an attenuator, attach the coaxial cables to the antennas to be used in the permanent installation. If the installation antennas are not available, small, inexpensive dipole or patch antennas can be used for verification purposes. If an adjustable attenuator is being used, dial in the amount of attenuation that corresponds to the path loss value expected for the microwave link in which the TRACER hardware will be installed. The path loss value can be calculated from a knowledge of the path length, or provided by a path study. Remember to subtract both antenna gain values from the attenuator level if these values have not already be accounted for.7. After setting up the RF pieces, examine the RF DOWN LED on the front panel of each TRACER 5045 unit. If the RF DOWN LED is illuminated (red), the corresponding TRACER 5045 is not receiving a suitable RF signal from the other TRACER 5045 unit. In this case, the receiving TRACER 5045 is either receiving a very weak signal, or no signal at all. If the RF DOWN LED is not illuminated, then the TRACER 5045 units are receiving a suitable RF signal. Suitable RF power levels for low error rate communication will range from -30 dBm to -78 dBm measured at the N-type connector input on the TRACER 5045 unit.8. Resolve any signal level issues before proceeding.ADTRAN provides a wireless link planning tool on our website. This link budget tool is constructed as an easy to use spreadsheet with dropdown menus so that the user can quickly change any of the link parameters (antenna size, coaxial cable type and length, frequency band, link distance, etc) and instantly see how the microwave path availability is affected. This tool is available at www.adtran.com/wireless and can be used online or downloaded for standalone use.

If this LED is illuminated, then the TRACER 5045 is receiving a relatively weak signal; however, if the RF DOWN LED is not illuminated, then the received signal is being suitably processed by the TRACER 5045 system. If you are receiving a weak signal (RF LOW is ON), please verify that the weak signal is not being caused by a faulty cable, an insufficiently tightened cable, or some other installation-related problem. Also, make sure an unreasonably large attenuation value has not been selected if you are using an attenuator on a workbench setup. Use the tables in Section 2, Microwave Path Engineering Basics, of this manual to select the proper free-space attenuation value (in dB) based on the estimated length of the microwave path. Remember to subtract both antenna gains (local and remote) from the attenuator setting.10. Command a link loopback in one TRACER 5045 unit and run a test pattern from the connected T1 equipment. This will verify the data path between the T1 equipment and the TRACER 5045 unit. Installing/Configuring T1 Hardware1. If possible, attach any or all of the intended T1 hardware to the TRACER 5045 units using the same workbench setup. This step offers the perfect opportunity to configure your T1 hardware for proper functioning with the TRACER hardware.2. To significantly reduce the probability of an unsuccessful field installation, resolve any remaining T1 equipment-to-TRACER 5045 configuration issues before field installation.External pattern generators are required to test data path integrity. A T1 BERT tester is suggested.
