Safety Precautions

Radio Frequency Radiation Hazard

This symbol indicates a risk of personal injury due to radio frequency exposure. The radio

equipment described in this guide uses radio frequency transmitters. Do not allow people to

come in close proximity to the front of the antenna while the transmitter is operating. The

antenna will be professional installed on fixed-mounted outdoor permanent structures to provide

separation from any other antenna and all persons.

WARNING: RF Energy Exposure Limits and Applicable Rules1 for 6-38 GHz. It is recommended that the radio

equipment operator refer to the RF exposure rules and precaution for each frequency band and other applicable

rules and precautions with respect to transmitters, facilities, and operations that may affect the environment due

to RF emissions for each radio equipment deployment site.

Worst case RF Energy Radiation occurs when maximum transmitter power and maximum antenna

gain are used. The referenced transmitter power is +33 dBm (2 Watts) and the antenna gain is 47

dBi (15 Ft diameter parabolic). The resulting EIRP is +80 dBm or +50 dBW. The minimum

separation distance for all persons from the antenna is 3 meters in this case. Refer to applicable rules1 for lesser

EIRP exposures.

Appropriate warning signs must be properly placed and posted at the equipment site and access entries.

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.

R-

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.

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.

R-

— Chapter 1. Overview HR-6500 Operations Manual

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.

station. Conditions that are typically monitored are listed below:

Standard Telemetry:

a) Heatsink Temperature

b) A Battery Voltage

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.

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. Each shipment includes an

equipment list showing the equipment ordered and shipped, including details about system and

equipment options.

— Chapter 2. Installation Instructions HR-6500 Operations Manual

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.

Chapter 3. 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.

Pendulum

R-

— Chapter 3. Mounting the Antennas HR-6500 Operations Manual

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.

R-

HR-6500 Operations Manual Chapter 3. 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.

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.

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.

Installation Overview

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 heterodyne repeater assembly, electric power system, battery boxes, solar panels,

and antennas should all be mounted before any wiring is done.

NOTE: Only qualified service or technical personnel should install the repeater.

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.

Earth, Ground, and Lightning Protection

When grounding the HR-6500 and associated equipment, follow the general guidelines in the

Peninsula Engineering Solutions application note, 650-0002-01: Installation Standards for Grounding

Requirements.

Note is available at www.peninsulaengineering.com Microwave RF Repeaters/Engineering Notes.

Installing the input power to the repeater includes installing the standard electrical service grounds.

However, you must also make sure that the heterodyne repeater enclosure is properly grounded to

an earth ground.

The enclosure includes an external grounding lug on the bottom surface as shown in the following

figure.

Figure 18 Location of Ground Lug on Heterodyne Repeater Enclosure

1. Connect the screw-compression ground lug to a suitable earth ground—copper ground rod,

copper pipe, ground ring, grounded steel building frame or similar ground point—using 2 to

4 mm, No. 12 to 6 AWG copper wire.

2. Carefully dress the wire along cabinet, and the mounting surface, to the Repeater Grounding

System or the Ground Rod. Recommend using CADWELD® to attach the ground wire to the

rod or ground point.

NOTE: When dressing the grounding wire, and forming it around corners; avoid making sharp bends

in the wire. Use a generous radius for each wire bend. Sharp bends will cause arc points for

lightning surges and strikes.

Chapter 5. Equipment Tests

Overview

This chapter describes how to test the HR-6500 equipment, to configure settings and to verify that it

is operating properly.

Test Equipment Required

Table 13, in Chapter 2, lists test equipment and tools required for testing the HR-6500 repeater.

Equivalent equipment may be substituted.

Configuring the Heterodyne RF Module

The HR-6500 is configured in the factory to customer and project requirements. Normally it is not

necessary to change the configuration settings. Should it be necessary to change settings, proceed

as follows:

Figure 21 Heterodyne RF Module

1. Power down the heterodyne repeater unit for safety if possible. At this point the HR should be

OFF anyway.

2. Locate the Heterodyne RF Module inside the unit enclosure. See Figure 21.

3. Remove the Control Cover to expose the configuration switches. The screws are small 2-56

FHP x .250 and are easy to drop and loose. Spare screws are included in the accessory kit.

4. Identify the configuration switches. See Figure 22.

5. See the Channel Plans in Tables 3 to 9 for the Channel MSB and LSB settings. The channel

pair must match the filter frequencies in the antenna coupling unit, ATCU!

6. Set the Channel MSB and LSB switches (2 left switches, 0~9 BCD) for the desired channel

pair. Note the receive and transmit frequency directions when selecting the pair. Certain

channel plans have alternate T-R spacing capability. Set ALT BAND SELECT jumper as

listed in the channel plan table.

a. Note: to enable the channel settings, the heterodyne unit must be power cycled.

Power down the unit for at least 10 seconds and then restart.

7. Transmit Power Amplifier Power is set using the 0~F HEX switch, 3rd from the left or RF

input end. Table 16 lists the power settings. The power level is referenced to the module RF

output SMA connector. Subtract transmit branch filter loss from this value to calculate the

level at the waveguide antenna port. Transmit branch filter loss is marked on the ATCU

panel. See Table 1 for typical loss values.

8. Squelch level is set using the 0~F HEX switch 4th from the left or RF input end. Table 16 lists

the squelch level settings. The squelch level is referenced to the module RF input SMA

connector. Add receive branch filter loss to this value to calculate the level at the waveguide

antenna port. See Table 1 for typical loss values.

9. Changes to Transmit Power and Squelch levels will be immediately enabled if the heterodyne

unit is powered ON. Otherwise, the changes will be effective on next power up.

Configuring DC Power

Heterodyne Units are ordered for 24V or 48V battery power. If the battery polarity is known, the input

polarity will be set at the factory. Should it be necessary to change the polarity jumpers, proceed as

follows:

1. Open the Heterodyne Unit enclosure door. Locate the DC Distribution Subassembly circuit

board at the inside bottom.

2. Tables 17, 18 and 19 list the connections and jumper positions for the available

configurations. Figure 10 shows the DC power connection schematic. Figure 23 shows the

board layout.

3. Wire jumpers are used at JP1 and JP2.

4. In applications were a single battery supply is used, recommend combining the A and B

inputs to provide internal DC/DC power supply redundancy and to normal standing alarms.

See Tables 18 and 19 for connection details.

5. In applications were power is run to the heterodyne unit thru conduit; connections can be

made to TB1 and TB2 on top of the DC Distribution Subassembly. Knockouts for 2ea ½-inch

conduits and 1ea 1-1/2 inch conduit are available for terminating the conduit.

a. The maximum wire size is 10 AWG.

b. Minimum recommended wire size is 14 AWG.

c. Wire size is determined by run length and allowable voltage drop.

6. In applications were power is run to the heterodyne unit via cords and Bulgin 3-socket plugs;

connections are to the Bulgin 3-pin jacks J1 and J2 on the enclosure outside bottom.

a. The maximum wire size is 12 AWG, cord OD range is 6 ~ 8 mm, (0.24 ~ 0.32-in).

b. Minimum recommended wire size is 14 AWG.

c. Wire size is determined by run length and allowable voltage drop.

4. Measure the DC voltage at TB1 1(+), 2(-) and TB2 1(+), 2(-).

Make sure that the voltage is within the operating parameters of the repeater:

 24 Volts DC: 20 ~ 30 VDC. Nominal lead acid battery voltage is 25.2 VDC when fully

charged and 27.0 VDC when being charged. Correct as necessary.

 48 Volts DC: 40 ~ 60 VDC. Nominal lead acid battery voltage is 50.4 VDC when fully

charged and 54.0 VDC when being charged. Correct as necessary.

5. If the ACU-SNMP alarm module is provisioned, it will start-up on power up. ACU start-up

takes about 5~10 seconds. Power LED should be ON and GREEN.

7. Once the Battery A and B alarms clear, then the repeater is powered and ready for testing.

8. Current Test: Measure the Battery A and B current flowing into the heterodyne repeater.

Each battery will normally supply close to half of the total current listed in the Technical

R-

-6

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.

R-

-6

— Chapter 5. Repeater Tests HR-6500 Operations Manual

6.3. Measure and record the power meter reading. 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.

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

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.

HR-6500 Operations Manual Chapter 6. ACU – SNMP Module Setup — 55

Chapter 6. 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.

R-

-6

— Chapter 6. ACU – SNMP Module Setup HR-6500 Operations Manual

B. ARP/Ping

1) Power ON the HR- ACU, no time limitation.

2) From a command prompt on the PC, issue the following two commands

Note: the ACU must have no IP address (0.0.0.0) configured for this to work:

ARP-S nnn.nnn.nnn.nnn xx-xx-xx-xx-xx-xx

Ping nnn.nnn.nnn.nnn

(where nnn.nnn.nnn.nnn is the desired ACU IP address, and xx-xx-xx-xx-xx-xx is the MAC

address)

3) 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.

2. Login: Default login credentials are admin/password. These can be changed on the Network

Settings screen.

3. The Device Status screen is displayed next. All operational status information is shown on

this page.

4. You are now connected and ready to configure remaining settings.

specific Email and SNMP alert settings can be configured.

Administration .... Displays the Administration Settings screen where general administrative

functions for the unit can be conducted. These include uploading a new

firmware file, resetting the unit, resetting all parameters to their default

settings, and uploading/download the Setting Keys file.

2. At the bottom of each screen where settings can be configured are a Submit button and a Cancel

Changes button. If you make changes and are satisfied with them, press the Submit button. New

configurations will be applied immediately. Press the Cancel Changes button before pressing the

Submit button to reset any configuration changes to what they were previously.

Note: Take care when making changes to Network Settings. Because these take effect

immediately, thus network connection to the HR-ACU will be lost and must be reconnected

using the new configurations.

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.

R-

-6

— Chapter 7. Maintenance and Troubleshooting HR-6500 Operations Manual

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

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.

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.

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.

e) Remove module.

To install the replacement module:

a) Orient the module with the power connector cable on top.

b) Mount the module on the heatsink panel, secure with mounting hardware.

c) Connect the SMA flexible cable. Normally the cable connects to J4. Use care to align the

SMA connector. Misaligned connectors can destroy the center pins.

d) Check the coax connection for tightness (8-inch/lbs)

e) Plug-in the module's power connector.

f) Power up the heterodyne repeater unit.

g) Verify operation by measuring frequency and level at SMA Monitor “MON”. Frequency should

be 10.000 000 00 MHz ± 2 Hz. Level at monitor is between 0 and -6 dBm.

DC/DC Converter Power Supply Assembly Replacement

The DC/DC converter power supply assemblies are available in 4 types based on input voltage and

power rating. Assemblies with the same part number can be used as replacements. There are two

power supply assemblies in standard heterodyne repeater units, A on left and B on right.

Removing the Power Supply Assembly

a) Power down the heterodyne repeater unit.

b) The B power supply is blocked by the door switch. Remove the door switch first. The switch

assembly is secured to the enclosure using 2 ea #6-32 screws and washer hardware.

c) Unplug the input and output cables from the DC Power Distribution PCB assembly.

d) Remove the nuts securing the assembly to the inside wall of the enclosure. Hardware is 6 ea

#10-32 nuts with nylon patch.

e) Slide the power supply assembly off the studs and remove from the enclosure.

Installing the replacement assembly

a) Slide the power supply assembly over the 6 studs on the enclosure wall and then secure with

#10-32 nuts.

b) Plug-in the input and output cables to the DC Power Distribution PCB assembly. The plugs

are size and orientation keyed.

c) Replace the door switch assembly over the B power supply.

d) Power up the heterodyne repeater unit.

e) Verify operation by measuring the power supply’s output voltage. 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.
