Electromagnetic Interference/ Compatibility

NOTE: Nearly every electronic device is susceptible to

electromagnetic interference (EMI) if inadequately shielded, designed or otherwise conﬁgured for electromagnetic compatibility.

FACILITIES

To avoid electromagnetic interference and/or compatibility conﬂicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy.

FIXED SITE

ANTENNAS

Transportable Repeater equipment is transported to and then set up at a ﬁxed location and operated as a ﬁxed control station or repeater . The antenna installation must comply with the following requirements in order to assure optimal performance and make sure human exposure to radio frequency electromagnetic energy is within the guidelines set forth in the above standards:

The antenna must be mounted outside the building. Mount the antenna on a tower if at all possible. The lo west point

of the antenna must be elevated a minimum of 10 meters above the ground. This may require the use of a coaxial cable extension for the antenna.

If the antenna is to be mounted on a building, then it must be mounted on the roof. If the antenna supplied with the repeater is used and the repeater cannot be located within the 12 ft. cable length, then a coaxial cable extension should be used.

As with all ﬁxed site antenna installations, it is the responsibility of the licensee to manage the site in accordance with applicable regulatory requirements and may require additional compliance actions such as site survey measurements, signage, and site access restrictions in order to insure that exposure limits are not exceeded.

Introduction

General

Compact Mechanical Design

State-of-the-Art Electrical Design

The Motorola PDR 3500 provides conventional analog, ASTRO™ ,

ASTRO CAI™ , and SECURENET™ capabilities in a compact,

software-controlled design. The station architecture and microprocessor-controlled Station Control Module allow for fast and reliable upgrading. FLASH memory in the Station Control Module allows software updates to be performed locally (using serial port), or remotely via modem.

The entire unit is housed in a lockable rugged, black aluminum extruded case weighing approximately 4l lbs. Internal components are mounted in a custom, removable chassis, designed to ﬁt a 19" rack.

Transmitter Circuitry

Receiver Circuitry

Station Control Module

The station transmitter circuitry is designed for 50% duty cycle operation at full rated power. Output power is continuously monitored by an internal calibrated wattmeter . The wattmeter output feeds a power control loop, continually adjusting and maintaining the desired output power. All adjustments are electronic, including deviation and output power.

The station receive circuitry features multiple bandwidth capability (12.5, 25, or 30 kHz, depending on band), as well as ASTRO digital operation. Injection signals for the 1st and 2nd local mixers are generated by frequency synthesizer circuitry and are electronically controlled by the Station Control Module. All receive signals (analog, SECURENET , ASTRO , and ASTRO CAI ) are detected and digitized before being sent to the Station Control Module; this provides improved audio quality , consistent throughout the cov erage area.

The Station Control Module is microprocessor-based and features extensive use of ASIC and digital signal processing technology . The module serves as the main controller for the station, providing signal processing and operational control for the station modules.

System Applications 4

Local Control The PDR 3500 is an APCO 25 digital repeater. The station is

identical in operation to the Quantar station, hence there is no local control capability . There is no digital-to-audio translation within the station. Local control style operation can be accomplished in several ways:

a. A portable radio may be used as an RF control station talking to

the repeater.

b. The station may be equipped with the wireline and the modem

options and routed through a DIU to a tone remote console. The T one remote console controls the station via wireline through the DIU. The wireline in this case is a local 4-wire cable.

External Duplexer Operation

Repeater RA or Cross Band Repeater Operation

The PDR 3500 must be used with an external duplexer when frequency spacing is less than 3 MHz. The duplexer isolation required for proper operation is approximately 60 dB. Doubleshielded coaxial cables must be used from the repeater to the duplexer.

The PDR 3500 can be conﬁgured for Repeater RA or cross band repeater operation by adding the wireline card and the Astro modem to the each repeater. The repeaters are connected together using the wireline port on each repeater. The cables are terminated in RJ-45 connectors.

The PDR 3500 uses the same RSS (Radio Service Software) as the Quantar/Quantro family. Some values shown in RSS screens may not be valid due to hardware differences between the Quantar Station and the PDR 3500. A thorough explanation of the differences will be given in the following sections.

Once the RSS Program has been loaded onto the PC (refer to Quantar RSS User’s Guide, 68P81085E35), the PC must be electrically connected to the PDR 3500 via the RSS port located on the top panel. For this connection, a 9-pin female to 9-pin male EIA232 cable is available (Motorola part number 30-80369E31) from the Accessories and Aftermarket Product Division (AAD, formerly known as Motorola National Parts). A cable can also be made using the wiring diagram in Figure 1.

Hardware Conﬁguration From the Main Menu, press “F2-Service. ” Press F2 again to arrive at

the Hardware Conﬁguration Screen.

1. The ﬁrst ﬁeld to verify is the Hardware Platform ﬁeld. The

PDR 3500 is designed using the Quantar proﬁle; it will not operate properly in any other mode.

2. The next ﬁeld to verify is the System Type ﬁeld. This ﬁeld

should be set to “Conventional.” The PDR 3500 does not operate as an ASTRO-TAC Receiver or DBS Base Station.

3. Next verify that the Rx Freq Band 1 and Tx Freq Band ﬁelds

list the correct ranges for receiver and transmitter.

NOTE: Rx Freq Band 2 should be set to “NONE.”

4. The PA Power Rating ﬁeld should be set to 25W (low power), and the Power Supply ﬁeld should show “AC LOW.” The PDR 3500 was designed using a Quantar low power station proﬁle. It will not operate properly using any other conﬁguration.

5. If the unit is equipped with a Wireline Card, verify that the Wireline ﬁeld under the options is set to 4-wire.

Once the Hardware Conﬁguration Screen matches the installed station hardware, press F8 to validate the conﬁguration. A popup message will notify the user of any errors in the conﬁguration. For a complete description of the Hardware Conﬁguration ﬁelds, please refer to the Quantar RSS User’s Guide (68P81085E35).

2. Using an R2670 or equivalent Communications System Analyzer, connect the RF out from the Analyzer to the Rx UHF-type connector on the station top panel.

3. Set the RF output level from the Analyzer to –90 dBm with no modulation, and set the frequency to PDR 3500 receive frequency.

4. With the Analyzer RF turned on, make sure the v alue sho wn in the RSS screen is –90 dBm. If it is not, type in “–90 dBm.”

5. Press F8 to save the calibration.

3. Power Out:

1. In the Alignment Menu Screen, tab over to the Tx Power ﬁeld and press F2 to perform the alignment.

2. For this procedure, connect the Tx UHF-type connector on the station top panel to the RF input of either a Motorola R-2670 Communications Analyzer, or to the input of an RF power meter.

3. Press F6 to keyup the station, check the output power level shown on the R2670 or RF power meter, and press F9 to dekey the station.

4. Enter the power from the meter in the ﬁeld shown in the RSS, then hit F7 for the PDR 3500 to adjust the PA power output level.

5. Once the unit adjusts the power, again keyup the station, read the RF power from the meter, dekey the station, enter the level in the RSS ﬁeld, and hit F7 again to adjust.

6. Repeat this cycle until the power out is as close to 25 Watts as possible. If the power output will not adjust properly, hit F4 to initialize the PA and restart the alignment procedure.
