HHRR--66550000 MMiiccrroowwaavvee LLiinneeaarr HHeetteerrooddyynnee RReeppeeaatteerr — Chapter 1. Overview HR-6500 Operations Manual 2 Functional Description 1. The HR-6500 assembly is an IF through repeater designed for medium to heavy route tandem applications that benefit from low latency. Little alignment is required, and the use of highly reliable components and minimum active circuitry eliminates most subsequent maintenance. The repeater assembly consists of an equipment mounting panel and heatsink, contained in an aluminum, weatherproof, enclosure. In most applications, the complete assembly is pipe-frame or tower-mounted. Front, side and bottom views of the repeater are shown in Figures 1, 2 and 3. 2. In addition to the HR-6500 repeater assembly, Peninsula Engineering Solutions offers accessory equipment consisting of antennas and mounting hardware, waveguide, and complete site power supply systems. The recommended antennas are solid or high performance types chosen per application. Basic Repeater 3. The HR-6500 heterodyne repeater receives 6 GHz microwave signals starting with an RF to IF, double-conversion, low noise amplifier/down-converter unit. At 140 MHz 2nd IF, signals are amplified and bandpass filtered. The IF includes automatic gain control, AGC, to compensate for variable input levels and propagation fading. In repeater applications, the 140 MHz IF output signal is connected to the IF input of the outbound HR unit via an external cable. In the transmit section of the HR-6500, the 140 MHz IF signal is moved to 6 GHz in a double-conversion, up-converter unit. A linear power amplifier follows the up-converter. The Level 4 linear power amplifier is rated 10 Watts at 1 dB gain compression point, GCP. 4. Bandpass filters and circulators, which form a duplexer network, direct the received signal to the LNA/down-converter and combine the power amplifier output with the received signal to a common antenna port for transmission (see Figures 4 to 7). These filters are located in the antenna coupling unit, ATCU, and mounted at the inside top of the enclosure. The heterodyne repeater supports frequency division duplex, FDD, radio link systems where separate frequencies are used in each direction. 5. A Delay Equalizer is added to the receive waveguide filter assembly to correct for slope and parabolic group delay introduced by the bandpass filters and branching networks. Equalized repeaters are recommended for high capacity systems and tandem repeater applications. 6. A CPR137G, waveguide flange, mounted on top of the enclosure, provides duplex 6 GHz RF connection to antenna feedlines. 7. An attenuator pad may be added to reduce the receive signal to approximate the recommended input level. An attenuator pad may be added to reduce transmit levels to less than can be internally set (+17 dBm at flange). Transmit pads may be required for very short hops for regulatory compliance. Pads are mounted on input of LNA/down-converter and output of the power amplifier. Nominal input and output power levels for various repeater channel configurations are listed at in Technical Summary following this section. Channel Selection 8. Receive and transmit bandpass filters are fixed tuned to the assigned channels. These channels are further selected using the rotary switches in the control section of the heterodyne RF module. These settings program the synthesized local oscillators per the channel plan associated with each heterodyne RF module. See Ordering Information and Spares for details on heterodyne RF modules. Channel frequencies must be known when the factory order is placed. 9. When operating as an IF thru repeater, it is possible to have different frequency bands per radio hop. The HR equipment at the repeater station may be mixed bands, i.e. Lower 6 GHz and Upper 6 GHz or Lower 6 GHz and 11 GHz. The HR units interconnect at 140 MHz IF.
HHRR--66550000 MMiiccrroowwaavvee LLiinneeaarr HHeetteerrooddyynnee RReeppeeaatteerr HR-6500 Operations Manual Chapter 1. Overview — 3 Squelch Operation 10. The heterodyne RF module includes a squelch function. This function will disable the following transmit power amplifier and block all transmit signals when active. The squelch is driven by the receive signal level, RSL. When the RSL is less than the set point, the squelch activates. The squelch may be disabled or set in 15 each – 1 dB steps. Squelch control signal runs from the 140 MHz IF output to the 140 MHz IF input on the outbound transmit repeater unit. If the connecting IF cable is disconnected or does not pass DC, the squelch will become active. The squelch may be disabled if required. Power Amplifier and ALC Adjustment 11. In digital radio applications, in order to maintain linearity over the entire signaling envelope, the transmit power amplifier operates at a reduced average power level to meet the output power level requirement as shown in Technical Summary. The power amplifier is part of the heterodyne RF module. There is a field-adjustable switch for setting the transmit power amplifier level. The settings are: 16 each - 1 dB steps. The recommended transmit power levels have adequate margin for tandem repeater station applications. Single repeater applications may operate at 1 to 2 dB increased power levels. Directional Coupler 12. A directional coupler, built into the power amplifier, provides a signal monitor point, “SAMPLE PORT - RF MON”. This point allows in-service measurement of transmit output power. The monitor point is calibrated for calculating the actual RF output power at the power amplifier and then, at the antenna port flange. When measuring transmit power, the power meter reading obtained, plus the loss (in dB) marked at the monitor point, minus the branching filter loss (in dB) marked on the antenna coupling unit, ATCU, equals actual antenna port transmit output power. Example 1 Amplifier Output Example 2 Antenna Port Output Power Meter indication +15.0 dBm Power Meter indication +15.0 dBm Cal Loss at RF MON +19.0 dB Cal Loss at RF MON +19.0 dB Power Amplifier Output = +34.0 dBm Tx ATCU Loss - 2.0 dB Antenna Port Output = +32.0 dBm Power Supply 13. External DC power supply operates the heterodyne repeater. Power supplies may be 24 VDC or 48 VDC. Either polarity is supported and is configured internal to the heterodyne repeater. Redundant, “A & B” battery power supplies are supported. Redundant selection is automatic. Operation from single “A” battery is permitted; internal power converters then share the single DC power input. 14. In areas where commercial power is available, an AC power supply can be provided. Typical power supplies are AC/DC rectifier/battery charger type with station battery. Although one AC power supply will provide ample current to power the repeater station, dual AC power supplies are recommended for greater reliability. The recommended dual AC power supply system also contains two rectifier/chargers and two sets of standby battery to provide power during AC power failures. Each battery is float charged while the power supply is on and has 100 Amp-hours as standard capacity. Additional batteries can be purchased if needed. The size of the battery plant is determined by station load and autonomy objective. System engineering will normally perform this analysis during planning and design phase.
HHRR--66550000 MMiiccrroowwaavvee LLiinneeaarr HHeetteerrooddyynnee RReeppeeaatteerr — Chapter 1. Overview HR-6500 Operations Manual 4 15. The heterodyne repeater station may be powered from alternative energy sources such as solar photovoltaic arrays and wind turbine generators with battery plant. Storage batteries and photovoltaic modules are selected on the basis of the capacity across the temperature range and during periods when the output from the solar PV array is low or not available. Controllers are used with the solar array to efficiently charge the batteries without overcharging. Peninsula Engineering Solutions can determine the solar and battery capacity. The location of the site should be specified when requesting assistance. 16. In locations where commercial power is not available and solar panel charging is impractical, then alternative power sources such as thermal-electric generator, TEG, fuel cell or motor generator are available. Power sources may be used in combination to create hybrid power solutions capable of operating in very demanding applications. In such applications, the battery installation should be given an environmental shelter according to the manufactures’ recommendations. Battery plant temperatures above and below nominal (+20C ~ +25C) can reduce capacity and usable life. Contact Peninsula Engineering Solutions for assistance in designing the best power supply system. Alarm Reporting 17. The HR-6500 heterodyne repeater includes an alarm system to remotely monitor the repeater station. Conditions that are typically monitored are listed below: Standard Telemetry: a) Heatsink Temperature b) A Battery Voltage c) B Battery Voltage d) RSL, RSSI, dBm e) Tx Power, Watts Standard Alarm Points: f) Heatsink Temperature Low and High g) A and B Battery Low and High Voltage h) Squelch Active i) RSL Low and High Levels j) Tx RF Output Low and High Power k) Heterodyne RF Module DC Alarm l) Enclosure Door Open 18. Alarm indications are sent as SNMP2 traps over Ethernet/IPv43 out-of-band data transport. Ethernet connections can be either ETH on copper (standard) or ETH on multi-mode fiber optic cable (optional). A standard MIB is provided that may be adapted to particular Network Management System, (NMS) applications. 19. Status of each heterodyne repeater can be observed on a web-browser screen generated by the ACU-SNMP unit. A duplex Ethernet/IP connection is required. 20. Alarm data concentration and transport is not included in the HR-6500 equipment. Such equipment is typically configured for the project application.

Overview — 9 Table 2 Recommended Transmit and Receive Power Levels per Modulation Type Modulation Type15 Level 4 PA Output16 Minimum RSL17 at Down-Converter Input System Gain18 16QAM 32.0 -75.0 102.0 64QAM 28.0 -70.0 93.0 128QAM 26.0 -67.0 88.0 Note: Peninsula Engineering Solutions may change performance specifications where necessary to meet industry requirements. See Heterodyne Repeater System Applications Considerations for additional guidance. 15 Modulations listed are the most popular types. List is not exclusive. If a modulation is not listed, contact the company for specific details. 16 Transmit power set point is reduced as the modulation becomes more complex. This power level provides adequate linearity as required by the system performance objectives. Multi-hop tandem applications may require additional power reduction to manage IMD summation depending on radio characteristics. Single repeater applications may increase power by 1 to 2 dB depending on radio characteristics. The ALC rotary switch is used to set the output power level. To calculate the repeater’s output power at the antenna port flange, take the power amplifier level output listed in this table, then subtract the transmit branch filter loss for the specific configuration from Table 1. For Example: Level 4 Power Amplifier Output = +32 dBm for 16QAM, Tx Branch Filter Loss = 2.5 dB, Output power at antenna port flange = +32.0 – 2.5 = +29.5 dBm. 17 RSL is typical for radio capacities found in 30 MHz channels, 21 ~ 27 MSymbols/sec. Actual RSL depends on terminal radio noise figure and associated modulation and traffic capacity. RSL at antenna port is determined by adding Rx Branch Filter Loss from Table 1 to value in this table. Recommended -75 dBm RSL minimum considers resulting transmit noise density. For Example: Down-Converter RSL = -75 dBm for 16QAM, Rx Branch Filter Loss = 3.5 dB, RSL at antenna port flange = -75.0 + 3.5 = -71.5 dBm. 18 At Antenna Port, assumes 3 dB Rx Loss, 2 dB Tx Loss.

HHRR--66550000 MMiiccrroowwaavvee LLiinneeaarr HHeetteerrooddyynnee RReeppeeaatteerr HR-6500 Operations Manual Chapter 1. Overview — 15 Ordering Information The HR-6500 Heterodyne Repeater Assembly is ordered by specifying the system model number HR-6500-XX and part number (Table 10). Attenuators (if required due to very strong input signal, > -20 dBm) are provisioned by specifying their part numbers. Transmission engineering must be completed before ordering because the necessary attenuator values are determined from the path calculations. Part numbers are listed in Table 11. When doing the initial system layout of a radio link which includes an HR-6500 Microwave Heterodyne Repeater Assembly, several factors must be considered prior to ordering, to ensure correct antenna connections and proper installation. Consider the following topics before ordering the HR-6500 Microwave Heterodyne Repeater: Repeater Transmit and Receive Frequencies Repeater frequencies are coordinated with the adjacent terminal radios. See the block diagrams for more detail. Orders cannot be accepted without firm frequencies. Peninsula Engineering can assist in determining the frequencies and assignments. Terminal Radio Modulation, Traffic Capacity and Repeater Transmit Power Level Repeater transmit power levels are set based on the modulation and traffic capacity of the adjacent terminal radios. Please include the modulation and traffic capacity details with the purchase order. Peninsula Engineering will determine the proper transmit power level. Modulations and traffic capacity beyond those listed in this manual may be possible to support, contact Peninsula Engineering Solutions for more details. Electric Power System The repeater site power system should be detailed during the system design phase. Peninsula Engineering Solutions can provide this design service and the power equipment. Power systems may include: Solar, Wind, AC, TEG, Motor Generator, Fuel Cell or other power sources. All power systems include a battery plant and associated charge control equipment. Battery capacity must be adequate for the load, location and power source. Antennas The types and sizes of antennas required to meet the system requirements. Transmission engineering can determine the antenna details. Transmission engineering and antennas are available from Peninsula Engineering Solutions. Feedlines Type and length required for antenna connections (including jumper assemblies); note that waveguide is available from Peninsula Engineering Solutions. Mounting Special requirements for the repeater and antennas specific to the intended tower or supporting structure. The repeater normally mounts outdoors in its all-weather enclosure. Peninsula Engineering Solutions can provide construction engineering support. Alarm Components The alarm equipment provides SNMP reporting over Ethernet on copper. It may be desirable to combine the reporting from multiple HR units or other equipment on site for further transmission to a Network Operations Center, NOC. Please refer to Applications Notes on alarm management. When ordering, specify a shipping destination and a billing address. Peninsula Engineering Solutions returns an order acknowledgment with the scheduled shipping date.

Installation Instructions HR-6500 Operations Manual 30 Pre-Installation Site Review Each site should be thoroughly reviewed before any equipment is mounted. Site review should include, but not necessarily be limited to, the following factors: Weather Determine whether environmental conditions necessitate special shielding of the repeater or other equipment. Security Determine whether some type of barrier is needed to protect equipment and if a security light is required. Aviation Review tower heights and obstruction lighting requirements as specified by the national aviation authority, e.g. US-FAA, US Federal Aviation Administration or TC, Transport Canada. Normally towers 200 Ft AGL and taller require obstruction lighting. Towers closer to airports have additional lighting and marking requirements. See FAA AC 70/7460-1K. File NOTAM21 as required during construction. Optional Site Equipment Determine whether additional site equipment, such as a convenience power outlet, pump, generator, or light is required, and, if so, where equipment is to be located and whether special enclosures for any equipment is required. Wiring and Wiring Access Determine any special wiring requirements. Cabinet Access Determine whether there is enough room for the repeater door to open, once mounted. The HR-6500 assembly can be mounted on a steel tower, on a steel pipe or square-rail frame, or on a wall. The length of all power leads should be limited and the wire size adequate to minimize the voltage drop. The repeater assembly, battery boxes, solar panels, and antennas should all be mounted before any wiring is done. Mounting-hole dimensions for the repeater enclosure are shown in Figure 12. Prior to cutting to length and connecting the waveguide feedlines, verify which HR Unit’s frequencies associates with each antenna port and associated terminal radio or repeater site. The heterodyne repeater’s receiving frequency and transmitting frequency are marked on the top of repeater, near waveguide antenna port. Coordinate site name is marked in the same location, when known. The waveguide feedlines are terminated in CPR137G, Waveguide Flange. The heterodyne repeater is not designed for pressurization. Use external pressure windows at the CPR137G, Waveguide Flanges if the feedlines are to be pressured or dehydrated. CAUTION: In an extremely hot and sunny environment, such as a desert, shading from direct sunlight may be necessary to prevent the heterodyne repeater and associated equipment from overheating. Locating battery enclosures in the shade is recommended. 21 NOTAM: Notice to Airmen, FAA or TC AIM

Mounting the Antennas Mount Antennas Mount all antennas, antenna feedlines, grounding, dehydration and lightning protection. Test the completed antenna system installation prior to heterodyne repeater equipment installation. Follow details of the site plan if available. Antenna Types Microwave Linear Heterodyne Repeaters can use any one of four typical parabolic antenna types:  Standard performance, single or dual polarized.  Improved performance, single or dual polarized (Deep Dish, PAR, PAD).  High Performance, single or dual polarized.  Ultra-High Performance, single or dual polarized. NOTE: Antenna type is normally determined by the system requirements. System path calculations, path data sheet, are used to determine the antenna sizes and type. Mount the antennas securely on adequate mounting structures. Mounting structures must meet strength, twist and sway requirements for 6 GHz antenna systems. Provide means for alignment adjustments. Antenna Alignment Coarse Alignment To initially orient the antennas: 1. Align the “bore-sight” of the antenna to the calculated azimuth as shown in the site layout or path calculations. Be sure to account for geomagnetic declination when using a magnetic compass. Azimuths are normally shown as True North. Geomagnetic declination varies by site location and typically drifts every year as the location of the earth’s magnetic pole moves. 2. Adjust the elevation to match the calculated elevation angle. Fine Alignment using test radios 3. Peninsula Engineering recommends using test radios22 to do the alignment over the hop. This is much easier than attempting to use the limited repeater level indications or measurements. The test radios also provide a talk channel to allow the alignment teams to rapidly communicate with each other. 4. Identify the polarization determined for the hop. Consult the antenna manufacturer’s documentation on identifying the vertical or horizontal antenna port on dual polarized antennas or how the feed assembly is installed and oriented in single (plane) polarized antennas. Failure to properly identify polarizations will result in antenna misalignment and violate the station license. 5. Attach the test radios to the proper antenna waveguide port at each end of the hop. 6. Consult the path calculations, PDS, for the net path loss calculated between the antennas. Correct for feedline losses when connected directly to the antenna waveguide ports. 7. Begin aligning the antennas. It should be possible to meet the calculated net path loss ± 1 dB. 8. Record the alignment and loss details. Provide the records to the end customer or controlling authority. 22 Path Align-R™ is a popular test radio. Manufactured by: Spectracom Corp, XL-Microwave, Pendulum
HHRR--66550000 MMiiccrroowwaavvee LLiinneeaarr HHeetteerrooddyynnee RReeppeeaatteerr — Chapter 3. Mounting the Antennas HR-6500 Operations Manual 34 Alternative Fine Alignment using heterodyne repeater level measurements 9. This method requires the HR-6500 repeater to be installed, connected to the antenna feedlines and powered up. See Chapter 4 for repeater installation details. 10. Connect the DVM to the RSSI BNC located on the bottom of the HR enclosure. The DC voltage increases with stronger received signal level. The range is 0 to +10 VDC. Refer to the factory Test Data Sheet, TDS, for calibration. 11. With a signal transmitted from the previous station, position the antenna for a maximum voltage reading on the meter. Align the distant end antenna for maximum receive power. 12. Align any other antennas toward their coordinate station similarly. 13. To generate a transmit signal from a Heterodyne Repeater alone or used with a modem, apply a CW carrier at 140 MHz, 0 dBm, thru a 3 to 6 dB attenuator pad to the HR IF IN Type N connector. The attenuator is required to provide a DC path to ground and activate the transmitter. 14. After the antenna orientation has been completed at both terminals and the repeater, Receive Signal Level (RSL) readings should be taken at all stations and logged for reference. Provide the records to the end customer or controlling authority. Antenna Feedlines The HR-6500 repeater uses waveguide feedlines. For the 5.9 ~ 7.1 GHz band, typical feedlines are elliptical waveguide such as EWP52, EWP63, EWP64, EP60, EP65 and EP70. The HR-6500 has CPR137G Waveguide Flanges at the top antenna port. The equipment end of the waveguide feedline must have a matching CPR137G flange installed. Two half height gaskets are used when a pressure window is installed. The antenna end of the waveguide feedline must have a connector flange that matches the installed antenna’s flange. Typical antenna flanges in this band are CPR137G and PDR70. Waveguide feedlines require dehydration equipment to maintain a dry atmosphere within the waveguide to prevent moisture accumulation which leads to corrosion and higher transmission losses. For sites that have adequate electric power available, AC or DC powered dehydration and pressurization equipment can be used. Mount the equipment at the tower base, or where convenient. This equipment normally requires weather protection. Tower mounted heterodyne repeater applications typically have shorter waveguide runs and thus, a smaller volume of air within the waveguide. Static desiccators are ideal in this situation. A static desiccator will passively dry air passed through its silica gel as daily temperature and pressure changes gently move the air. These units do not require any power to operate and provide 1 to 2 years field lifetime before requiring replacement or service. Peninsula Engineering recommends mounting static desiccators inside a weatherproof enclosure to protect against aging from direct sunlight. Peninsula can provide an assembled dual static desiccator enclosure with pressure test ports. See manufacturer’s specifications and recommendations when considering static desiccators. Dry Nitrogen is another method to keep waveguides dry without using power. Nitrogen supplied in high pressure bottles is reduced in pressure with a regulator and then passed to a gas pressurization manifold with distribution to the feedlines. Nitrogen replaces the air within the waveguide (purged at installation) and the positive pressure helps force moisture away from entering the waveguide. To warn of an empty gas bottle, external alarm equipment can be optionally provisioned with a low pressure switch that can be added to the pressurization manifold. When gas pressure drops below 1 psi, 7 kPa, a warning alarm is issued.

Mounting the Antennas — 35 HR-6500 repeater station configurations require one feedline per equipment antenna port, typically:  One for the primary West antenna  One for the primary East antenna  One per direction and polarization in Y-Junction applications The allowable transmission loss for antenna feedlines is specified in the site plan or path calculation, path data sheet documentation for the project. Do not install feedlines different than as specified. Feedline Installation To install waveguide feedlines: 1. Install the top connector (goes to the antenna). Use a flaring tool for best attachment and impedance, Z0, match. 2. Raise the waveguide up the tower to the antenna. Use a hoisting grip. 3. Position the waveguide and secure the top section. Carefully bend the elliptical waveguide to align with the antenna flange. Be mindful of the bend and twist specified limits of the waveguide. If necessary, use rigid twist and bend sections to aid in alignment. 4. Connect the waveguide to the antenna. 5. Securely install the feedline so that it reaches to the installation site of the HR-6500, with enough room to connect to the heterodyne repeater. 6. Secure the cable to the tower or structure about every 3 feet or 0.9 meters. 7. Carefully measure and cut to length the waveguide. 8. Terminate the waveguide with a CPR137G flange connector. 9. Position the waveguide and secure the bottom section. Carefully bend the elliptical waveguide to align with the repeater equipment top flange. Be mindful of the bend and twist limits of the waveguide. If necessary, use rigid twist and bend sections to aid in alignment. 10. Flexible twist-flex waveguide jumper may be used at either end if needed. These jumpers have higher loss and shorter life than rigid twist and bend sections. 11. Trial fit the bottom connector to the repeater equipment top antenna port flange or intended flange location. Do not permanently install until the feedlines are sweep tested. 12. Install waveguide grounding kits. Normally the waveguide is grounded at the top and bottom and at the shelter entrance. Follow grounding practices prescribed by the controlling authority. 13. Pressure windows are recommended at the repeater equipment top antenna ports. 14. Install dehydration equipment.

Mounting the Antennas HR-6500 Operations Manual 36 Lightning Protection Peninsula Engineering Solutions strongly recommends installing protection on the tower, structure and on all feedlines to the heterodyne repeaters. A direct lightning strike can damage any electronic equipment. Damage resulting from a lightning strike is not covered under the equipment warranty, whether or not lightning protection is used. However, using lightning protection can minimize the risk of damaging a repeater unit, and of losing equipment operation during thunderstorms. Elliptical waveguides are protected by installing grounding kits, typically at the top, bottom and at shelter entrance. Lightning rods mounted adequately above the highest antenna or power equipment, provide a diversion path for lightning strikes. Multiple lightning rods may be required. Towers, shelters and all equipment must be bonded and grounded to minimize any potential differences that can occur due to a lightning strike. Follow grounding practices prescribed by the controlling authority. Sweeping the Antenna Feedlines Sweep testing of the installed feedlines and antennas is recommended. Sweep testing is the same as performed at a terminal radio site. Measurement of impedance match and insertion loss over the operating frequencies insures that the antenna system is installed properly and is ready to perform. Most microwave operating companies have developed their own performance standards for antenna systems. Use such standards if available. If company standards are not available, consider the following:  Sweep frequency range: 5,925 ~ 7,125 MHz or across assigned channel bandwidth.  Impedance Match: 20 dB Return Loss or 1.2:1 VSWR across the channel bandwidth or better. If tunable connectors are provisioned, adjust the tuning screws to optimize the match.  Insertion Loss: Per calculated. Typical waveguide loss23 is 1.4 dB/100 Ft or 4.6 dB/100 m.  Distance to Fault, DTF: Measure Return Loss of the antenna system components and isolate troubles. Use DTF function of Anritsu Site Master™ (or equivalent) test equipment. If the impedance match or insertion loss is not met, troubleshoot the feedlines and antennas for the source of the problem. Use the “Distance to Fault” function to assist in localizing the trouble. Correct as required before proceeding. 23 EWP63, EP65. Consult manufacturer’s specifications for loss at the intended frequencies.

Mounting the HR-6500 — 39 Figure 15 Example of Solar and Wind Power Installation Mounting the Repeater The HR-6500 has a detachable rear mounting bracket. The mounting holes fit 3/8-inch to 5/8-inch hardware. Mounting-hole dimensions for the mounting bracket are shown in Figure 12. The HR enclosure attaches to the mounting bracket using 3/8-inch hardware provided. The enclosure is first aligned using the ½-inch alignment spacer and slot in the mounting bracket. The enclosure is secured to the mounting bracket using the 3/8-inch hardware provided. The HR unit may be lifted to a high mounting location using the lifting plates attached to the sides of the enclosure. Use carabineers and a rope cable sling for balance. The top rear edge with the alignment spacer will tip to the rear making attachment to the mounting plate easier. Avoid using a rope cable across the top of the enclosure as this can damage the waveguide antenna port. Pipe Mount The mounting bracket may be attached to 4.5-inch OD pipes using the outer hole pattern or 2.375 ~ 2.5-inch OD pipes using the inner hole pattern. Pipe saddle and U-bolt clamps24 can be used to attach the bracket. Cut off excess U-bolt thread near the mounting nut. This provides clearance to the HR heatsink fins. Figures 13, 14 and 16 show the suggested pipe mounting. 24 Clamp sets are provided by others.

HHRR--66550000 MMiiccrroowwaavvee LLiinneeaarr HHeetteerrooddyynnee RReeppeeaatteerr HR-6500 Operations Manual Chapter 5. Repeater Tests — 51 Summary. If either battery input has a low or zero current, check the battery source and distribution system. A battery source with lower voltage will typically supply less current.  Record A and B currents for reference. 9. The heterodyne repeater can operate on a single A or B battery input when needed. Each module can draw power from both DC/DC converters and thus either battery input. When one battery source is removed or failed, all the current will flow into the remaining working battery feed. This can be observed by switching OFF one of the battery feeds, observe, then restore this feed to ON and then switch OFF the other battery feed, observe. Transmit Power Adjustment At this point, the antennas should be mounted, feeders swept, and antennas aligned. The heterodyne repeater’s power amplifier (PA) has been factory set to the specified output power level per the system modulation, when known. Greater than recommended power levels can result in amplitude distortion, increased error vector magnitude (EVM), radio and line errors (BER). Less than recommended power levels may have been selected by transmission engineering (e.g. short hops or tandem hops). Refer to system path calculations and path data sheets for details. To measure and adjust PA output power: 1. Three methods may be used to measure PA output power: A. Tx Power Voltage and factory Test Data Sheet calibration. (Easiest) B. ACU Web Page user interface. C. RF Power Meter at RF MON – SAMPLE PORT. (Most Accurate, Most Work!) 2. A signal source must be present: 2.1. Repeater Applications: The far end transmitter must be transmitting at this time. 2.2. Heterodyne Terminal Applications: An IF modem sending 140 MHz signal to IF IN. 2.3. Test: A suitable signal source sending 6 GHz RF or 140 MHz IF signals. 3. Confirm the Power Amplifier is active; no HET DC fault should be present. 4. Method A. 4.1. Use a DVM and BNC adapter to measure the Tx Power Voltage at the BNC connector on the enclosure bottom. 4.2. See the factory test data sheet (TDS) for voltage to power (Watts) conversion. 4.3. Record the PA Output Power Level. 5. Method B. 5.1. Connect to the ACU Web Page and read the Tx Power value. 5.2. Record the PA Output Power Level. 5.3. Note: ACU network connections must be previously setup. See Section 6. 6. Method C. 6.1. Calibrate the RF Power Meter for 6 GHz operating frequencies. 6.2. Remove the SMA Termination and then connect the power meter to the RF MON – SAMPLE PORT on the side of Power Amplifier. This is an SMA-female connector. A right-angle adapter with a between series (e.g. SMA to N) adapter (if needed) to fit the power meter sensor are needed to access the test port. See Figure 25.

Typically, this reading will be between -3 and +16 dBm at RF MON. 6.4. Replace the SMA Termination. 6.5. Add the Cal Loss marked near the RF MON (see Figure 25) to the power meter reading, the result is the Power Amplifier Output Power. 6.6. Record the PA Output Power Level. 7. Power Adjustment 7.1. Compare the Power Amplifier Output Power reading to Table 2, using the listing for the radio modulation type used. 7.2. Set the Tx Power Switch as required setting the power amplifier output level equal to the listing in Table 2 and per Table 16.  Note: Lower levels may have been selected by transmission engineering, please refer to system path calculations and path data sheets for details. 7.3. Once the power levels have been set, confirm the ACU Transmitter Power alarm is clear. If the Tx PWR alarm remains active and the transmit power is correct, then the ACU alarm point must be reset. Please refer to the ACU section for details. 8. To determine the Antenna Port Output Power Level, subtract the Tx Branch Loss from the Power Amplifier Output Level. The Tx Branch Loss is marked on the ATCU panel above the PA. Include any transmit attenuator pad loss if equipped.

Repeater Tests — 53 Receive and Transmit Attenuator Pads Receive, Rx, pads attenuate input signals that are greater than can be compensated by the repeater amplifier’s AGC circuits. Receive pads are installed on the RF Down-Converter input (RF IN) jack. Transmit, Tx, pads attenuate output signals. Transmit signals can first be reduced by adjusting the PA Power Set Switch. In cases of very short hops, more power reduction may be needed. In these cases a Tx Pad is normally installed. Transmit pads are installed on the Power Amplifier output (RF OUT) jack. Power Amplifier output should be reduced to between +19 and +30 dBm before adding an attenuator pad. Pad Installation: 1. If required in the field, the Rx/Tx attenuator pads should be installed at the RF input or output of the heterodyne RF module. 2. To install the pad, turn OFF the DC power supply first. 3. Disconnect the input or output semi-rigid coax cable from the heterodyne RF module. 4. Connect the SMA male end of the pad to the module’s SMA female input or output; and then connect input or output cable to the female end of the pad. 5. Check all coaxial connections for tightness (8 in-lbs). 6. Turn ON the DC power supply. 7. Set output power level by adjusting PA Power Switch. ACU – SNMP Network Configuration The ACU – SNMP module reports status and alarms via IP on Ethernet. Private IP Network or Public Internet may be used for message transport. Each ACU must be configured for proper reporting. Section 6 details ACU setup. Radio Link Tests Once the repeater levels have been set and confirmed and antenna alignment is accepted, then confirm microwave signals are received at each terminal radio. Observe and record the receiver AGC or RSL indications for reference. End to end link tests can now be run. These tests may typically include un-faded BER, radio errors, system thermal and intermodulation noise. Refer to the radio terminal equipment documentation and system engineering requirements for the link test plan.

ACU – SNMP Module Setup The ACU – SNMP module is factory configured. This module must be configured for the customer network in order to communicate. This section describes network setup plus the procedure to change alarm conditions. Network Setup Connect the local Ethernet to the Heterodyne Repeater Unit. Connect to the RJ-45 connector on the enclosure bottom or Fiber ST Connectors on the enclosure bottom. See Figure 3 for I/O connection detail. The ACU Copper Ethernet RJ-45 connector jack may be connected directly to a LAN switch or router. The ACU Fiber Optic Ethernet ST connector jacks must be first connected to compatible multi-mode fiber optic transceiver. The F/O transceiver may be part of a media converter, switch or other network device. The fiber optic pair is used as the supervisory communications path from a tower mounted heterodyne unit to a ground mounted network switch or router. Fiber optic pair provides improved immunity to electrical interference on such longer runs. The LAN switch, router or similar network collection point plus transmission means from the microwave site to a network operations center, is provided by the user. ACU – SNMP messages are carried by “Out-of-Band” network transport. Accessing the HR-ACU via the Web Page User Interface 1. Assign and IP address to the HR - ACU using one of these two methods: A. OmniDiscover utility application (Best Method) 1) This is a small computer program included with the documentation CD. 2) Install OmniDiscover application on a Personal Computer (PC) and then connect the PC to the local Ethernet. 3) Power on the HR-ACU and perform the following steps within 5 minutes. This is an intentional limitation. If 5 minutes passes, network data cannot be modified without power-cycling the HR-ACU unit. 4) Open the OmniDiscover application, and select Search on the top menu bar. The ACU will be displayed in the main window including the MAC address, Site ID, and default Subnet Mask (255.255.255.0) 5) Right click the ACU line, and select “Setup” from the menu that appears. 6) Enter the desired IP Address, Subnet mask (if not default) and Gateway router address you want to assign to the ACU. 7) Press/click the “OK” button and you’ll be returned to the main OmniDiscover window where you should see displayed the network address configurations just entered. 8) Right click the ACU line again, and select “Web”. The ACU login will be displayed. 9) Alternatively, open a Web Browser and type the ACU’s IP/URL in the address line: http://nnn.nnn.nnn.nnn. The ACU login will be displayed.

HHRR--66550000 MMiiccrroowwaavvee LLiinneeaarr HHeetteerrooddyynnee RReeppeeaatteerr HR-6500 Operations Manual Chapter 7. Maintenance and Troubleshooting — 71 Chapter 7. Maintenance and Troubleshooting The HR-6500 active components are the linear heterodyne RF module, 10 MHz reference oscillator, Alarm Control Unit, DC/DC converters and the optional media converter equipment if equipped. Heterodyne Repeaters provide long field operating life, often 15 to 20 years. Technologies and traffic needs often drive upgrades or replacement rather than old age. Routine maintenance checks of the heterodyne repeater and its supporting equipment will ensure reliable operation and early detection of problems. Routine Maintenance Peninsula Engineering Solutions recommends an annual maintenance schedule for the heterodyne repeater. The following is a procedure for routine maintenance: 1. Observe the general condition of the installation site and correct any problems. 2. Verify that the heterodyne repeaters and all associated hardware, including antennas, are securely mounted and properly in place. 3. Check input electrical wiring and power system for damage and ensure that connections are tight. Replace any wiring that is suspect. 4. Check any battery terminals for corrosion; clean terminals, if necessary. 5. Check the battery storage capacity condition. Battery impedance testers are recommended. Battery life expectancy is typically 5 to 10 years in an outdoor environment. Replace any weak batteries or cells. 6. Clean solar panels and remove obstructions, if applicable. A mild detergent and water are recommended. Clean solar panels when they are cool, avoid putting cold water on hot panels, this may cause damage. Dirt, thick dust and bird droppings can reduce the output by 30%. Shadows from antennas, lightning rods or trees reduce PV output. Life expectancy of PV arrays is 20 years or more. Horizontally tilted panels collect more soils than if tilted 45° or more. Lower tilt panels should be cleaned annually. Greater tilt panels may be cleaned every 3 years. CAUTION: Follow manufacturer’s instructions when cleaning solar panels. Abrasive or acetone-based solutions can cause damage. 7. Look for lightning strike damage. Solar panels with “holes” punched in the backing material indicate a lightning strike. Damaged solar panels or equipment should be replaced. 8. Check antennas and feedlines for damage and ensure that connections are tight. 9. If the feedlines are pressurized, check that pressure is holding correctly, dehydrators are working or Nitrogen gas tanks are full. 10. If static desiccators are used to dry the feedlines, check the desiccant color. Blue or Orange is normal, Pink indicates the desiccant is full of water and needs changing. Static desiccators should be changed typically, about every 1 to 2 years. 11. If feedline pressure is zero or desiccants are very pink, it’s best to check the feedlines for water. Drain and dry as required. Inspect for corrosion, correct or replace as required. 12. Check the alarm control unit, ACU, for indications of alarms or trouble. 13. Observe the Receive Signal Level by measuring the RSSI / RSL Voltage at its BNC connector. Refer to HR-6500 Test Data Sheet for signal level value. Compare to records.
HHRR--66550000 MMiiccrroowwaavvee LLiinneeaarr HHeetteerrooddyynnee RReeppeeaatteerr — Chapter 7. Maintenance and Troubleshooting HR-6500 Operations Manual 72 14. Observe the Transmit Power Level by measuring the Tx PWR Voltage at its BNC connector. Refer to HR-6500 Test Data Sheet for power value. Compare to records. 15. Measure the DC battery load currents. Compare to records. Administrative Requirements The US FCC, Federal Agency or other local Telecommunications Administrations may require measurement of the output power of the heterodyne repeater at installation or when any changes are made which cause the output power to change. Using the power meter method, measure and log the output power as directed in Chapter 5. Troubleshooting Reported alarms may appear in combination due to the root cause. The alarm matrix, Table 21 provides information about the probable cause. Assumes an IF repeater configuration of 2 heterodyne units.

PA current out of range. Possible PA section failure. 14 X Heatsink Temperature out of range, low or high. If the received signal at the terminals is low but does not indicate a complete failure on heterodyne repeater, then, the most likely cause is low voltage from the batteries. Low voltage is an indication of a possible DC/DC converter power supply failure, battery failure, or a failure of the charging system. Check the batteries and all power lead connections. If solar panels are used, be sure they are not obstructed from sunlight and that the surfaces are clean. If an AC power supply is used, low voltage is probably the result of a power failure, the duration of which exceeded the reserve power limits of the standby battery. Check the standby battery in accordance with the instructions given by the manufacturer of the power supply. NOTE: Contact the Customer Service Department of Peninsula Engineering Solutions whenever problems with the unit cannot be resolved.

Heterodyne Repeater fails overnight and then restarts the next day (Solar Powered) Improper PV Charging  Check the PV array for damage, obstructions or dirt. PV Array wired to wrong voltage  Check the PV open circuit voltage, Voc.  Typically the Voc will be 1.5 to 2 x the battery nominal voltage. If Voc is more than 3 x the battery nominal voltage and PWM29 type PV controllers are used, the array is mis-wired.  Voc may be greater only if MPPT30 type PV controllers are used. Alarm Conditions  Check for alarm conditions and resolve, if necessary. Battery capacity low  Batteries may be worn out or undersized, replace and correct as necessary. Prolonged storms  Storms or series of storms can reduce battery recharging for days. Batteries may be fully discharged causing the system to fail. Re-evaluate the power source capacity, increase the PV array or add wind turbine generators, increase the battery plant Ah capacity. 29 PWM: Pulse Width Modulator. PV Controller type that uses a rapid switch to reduce the average charging current when batteries are fully charged. PV Array Voc should be 1.25 to 2.0 x the nominal battery voltage. Higher Voc can indicate the array is mis-wired (series instead of parallel) resulting in less charging current and power. 30 MPPT: Maximum Power Point Tracking. PV controller type includes a DC/DC converter to “step down” higher voltage PV arrays. Maximum Voc is limited to the maximum rating of the MPPT controller, typically 150 to 200 VDC.

Maintenance and Troubleshooting HR-6500 Operations Manual 76 Heterodyne RF Module Replacement Heterodyne Repeater RF Modules are band segment and channel plan specific. These modules must be configured for the channel pair assigned to the heterodyne repeater and must match the bandpass filters in the Antenna Coupling Unit. Modules with the same part number can be used as replacements. Configure the replacement module’s frequency, Tx power level and squelch before installing in the heterodyne unit if possible. See Chapter 5: Configuring the Heterodyne RF Module. When a heterodyne RF module must be replaced, do the following: a) Power down the heterodyne repeater unit. b) Unplug module’s power connector. c) Disconnect input and output SMA semi-rigid cables. d) Disconnect the IF input and output SMA flexible cables. e) Disconnect the Reference Oscillator SMA flexible cable. f) Disconnect the BNC cables from RF Out Level and RSSI (ALC) monitor points. g) Remove mounting hardware (8 ea #6-32 screws and washers). Hardware uses Socket Head Cap screws. The socket head cap screw hardware takes a 3/32 or 7/64-inch Hex Allen Wrench. h) Remove module. To install the replacement module: a) Apply heat sink compound to the mounting surface of the amplifier. Use a very thin layer. b) Mount the module on the heatsink panel, secure with mounting hardware. c) Connect the two BNC cables to DC monitor points. d) Connect input and output SMA flexible and semi-rigid coax cables. Use care to align the SMA connector. Misaligned connectors can destroy the center pins. e) Check all coax connections for tightness (8-inch/lbs) f) Plug-in the module's power connector. g) Power up the heterodyne repeater unit. h) Verify operation by measuring power at SMA power monitor, PWR MON. i) Set output power by adjusting Tx Power Level switch per Chapter 5. j) Confirm the Transmitter power alarm clears. Adjust the Tx Power calibration as required. ii) Power Amplifier’s RF Detector DC sensitively and output can vary, thus requiring calibration adjustment.

Voltage at the output connector, (DC Power Distribution J5, J6), should be 12.5 VDC ± 0.2V. Keeping Spares Because microwave heterodyne repeaters are often used to provide critical coverage, customers are advised to follow a sparing policy. While most telecommunications carriers or system operators have internal policies relative to equipment sparing, in the event that one does not exist, Peninsula Engineering Solutions recommends maintaining a minimum of one (1) spare unit for every increment of 8 units or fraction thereof. This assumes that all spares are immediately available to the technician in need for installation. Remember that heterodyne RF modules are band plan specific. When travel time to a site is long or access is difficult (helicopter, hike or horse), then, more spares located close to or at the repeater site are recommended. Maintain stored spares in anti-static packaging. Storage locations should be dry and protected from salt air or corrosive atmospheres. Each organization should develop a company-specific, equipment-specific policy that meets their needs, taking into account geographic considerations and the quantity of repeaters used in the network.
