Tune-Up Procedure (Draft)
See the following manual excerpts (Chapter 10 and Chapter 13 of MOTOTRBO MTR3000 Base Station /
Repeater, Basic Service Manual) for instruction on performing the field digital upgrade, operational verification,
and programming / tuning.
All adjustments are software controlled and are pre-set at the factory. Certain station operating parameters can be
changed using Customer Programming Software (CPS), within predetermined limits. Examples include transmit /
receiver operating frequencies and transmitter power level.
After the base station / repeater and ancillary equipment have been mechanically installed, properly cabled, and
power applied, the equipment must then be optimized; that is, before placing the base station / repeater in
operation. The cable required is a standard “USB A to B” cable. Optimization is performed through the Customer
Programming Software (CPS), kit number RVN5115.
After the base station / repeater is operational, the base station / repeater’s codeplug data must be copied to a
PC- compatible computer.
Optimization involves the following tasks:
1. Reading the base station / repeater codeplug from the base station / repeater (this ensures a match between
the base station / repeater serial number (resident in the codeplug) and the serial number (part of the
customized base station / repeater codeplug data) that is written back to the base station / repeater (see task
5).
2. Customizing the base station / repeater codeplug and saving the data to the base station / repeater.
3. Aligning the base station / repeater for:
- Modulation Limit
- Speaker Level
- Station Reference
- MTR2000 PA Calibration
- Receiver Squelch Adjust
4. Performing post-optimization procedures.
5. Writing the customized codeplug to the base station / repeater codeplug.
For details on these tasks, refer to the Customer Programming Software (CPS) Online Help.

This feature is used to allow entry of the transmitter (Tx) output power coefficients of an MTR2000
Power Amplifier (PA) into the MTR3000 tuning codeplug.
Since an upgraded MTR2000 Base Station/Repeater does not have its PA upgraded, its PA
calibration coefficients must be entered into the tuning codeplug, as the non-upgraded MTR2000 PA
does not have an Electrically Erasable Programmable Read-only Memory (EEPROM). The
calibration coefficients, which exist on a sticker on the face plate, consist of two 7 digit hexadecimal
numbers and two 6 digit hexadecimal numbers. The sticker itself is created and applied at the factory
in which the PA was calibrated.

13.5.2 Wireline Rx Equalization – 2800 Hz Tuning
The Rx Equalization feature allows the frequency response adjustment of the Rx Audio relative to a
specified rated system deviation, to compensate (equalize) for the response of the wireline backhaul
network itself. This section outlines the procedure for high frequency adjustment. Perform this
procedure only after setting the Wireline Receive Level. Refer to Section 13.5.1 on page 13-5.
The Rx Equalizer is adjusted relative to the response at 1 kHz. Note the 1 kHz response observed
when performing the tuning procedure for Wireline Receive Level. Equalizer adjustments are
approximate. Typical adjustments range from 0 dB to approximately +6 dB.
Note The Tuner aligns this parameter in a 12.5 kHz channel spacing, so 60% is 1.5 kHz of
deviation. If the CPS is set for 25 kHz operation, the base station/repeater will automatically
scale the deviation by a factor of two when it is outside the Tuner environment.
Note Programmed TPL and DPL squelch requirements are automatically disabled for the tuning
frequency while in the Tuner environment.
Note It is imperative that the load the Wireline board is driving, matches that of the Wireline
board’s source impedance setting noted in the Tuner environment. Optimally, it is
recommended to use the actual load which is used during normal operation of the radio.

Base Radio Module Overview
The Motorola MTR3000 Base Station / Repeater (BR) provides a modular, flexible analog and digital station design
for today's communication systems and of the future. The stations are available for use in Analog Conventional,
Digital Conventional (MOTOTRBO), LTR Trunking, Passport Trunking, MOTOTRBO Capacity Plus Trunking, and
MOTOTRBO Connect Plus Trunking configurations.
The MTR3000 BR can either be configured as a stand-alone base station / repeater or as a base station / repeater
connected to a back-end network, as in the case of operating in IP Site Connect mode. As a base station /
repeater, it listens on one uplink frequency, and then re-transmits on a downlink frequency thus providing the RF
interface to the field subscribers. When configured for analog station operation, the BR is designed to operate with
most existing analog systems, therefore making a smooth migration to the MOTOTRBO system.
When configured for digital operation, the BR offers additional services. The digital BR operates in TDMA mode,
which essentially divides one channel into two virtual channels using time slots; therefore the user capacity is
doubled. The BR utilizes embedded signaling to inform the field radios of the busy/idle status of each channel
(time slot), the type of traffic, and even the source and destination information.
Note: When configured in Digital Mode, the BR can only be used as a repeater.
Note: At any given time, the BR either operates as a digital repeater or as an analog repeater.
The MTR3000 BR is divided into functional modules that separate the frequency band specific and transmitter
power specific circuits from other circuits and has separate modules for the control interface. These modules are
self contained functional blocks with module-specific alarms. This design facilitates the field replaceable unit
(FRU) concept of field repair to maximize system uptime.
Indicators and Connections
This section describes the LED indicators and connectors provided on the base station / repeater. The set of
LEDs indicate the operational status of the base station / repeater. There are two sets of connectors for devices
external to the base station / repeater:
• One set connects to external devices to enable full operation of the base station / repeater. These are
located at the back of the base station / repeater.
• Another set connects to external devices for servicing the base station / repeater. These are located on
the Station Control Module.
LED Indicators
A set of eight LEDs is located on the base station / repeater front bezel. The position of the eight LEDs on the
front bezel is shown below. These LEDs indicate the status of the base station / repeater during normal operation.

Receiver Overview
The Receiver Module consists of a Receiver RF board in a clamshell housing assembly. It provides the Receiver
functionality for the MTR3000 Base Station/Repeater and performs highly-selective bandpass filtering and dual
down-conversion of the desired RF signal. A custom Receiver IC then performs an analog-to-digital conversion of
the desired received signal and outputs a differential data signal to the Station Control Module (SCM). The
Receiver Module kit contains an on-board, varactor-tuned preselector, which covers multiple frequency ranges.
The UHF range receivers utilize an external coaxial-resonator bandpass filter (BPF) for some configurations but
not the 800/900MHz range Receivers.
Overview of Circuitry
The Receiver Module contains the following circuitry:
• Frequency Synthesizer Circuitry – consists a phase-locked loop and Voltage-Controlled Oscillator (VCO),
generates the first LO injection signal
• Varactor-tuned Preselector Filter / Fixed Preselector Filter (800/900 MHz) – provides bandpass filtering of
the station Receiver RF input
• Receiver Front End Circuitry – performs filtering, amplification, and the first down conversion of the
Receiver RF signal
• Custom Receiver IC Circuitry – consists a custom IC which performs the second down conversion,
filtering, amplification, and analog-to-digital conversion of the receive signal
• Analog to Digital Converter (ADC) Converter Circuitry – converts analog Receiver status signals to digital
format for transfer, upon request, to the SCM
• Local Power Supply Regulation – accepts +8V, +10V and +14.2V inputs and outputs +2.775V, +3.3V, +5V,
+10V, and +14.2V operating voltages

Exciter Overview
The Exciter Modules (in conjunction with the Power Amplifier Module) provides the transmitter functions for the
station. Contained within a metal clamshell housing, the Exciter board generates a low-level modulated Radio
Frequency (RF) signal which is input to the power amplifier module for further amplification and output to the
transmit antenna. The Exciter Modules interfaces directly with the Station Control Module (SCM), which provides
control signals and monitoring, and routes transmit audio to the Exciter.
The RF carrier is generated by a frequency synthesizer consisting of synthesizer circuitry and Voltage-Controlled
Oscillator (VCO) circuitry. Exciter module control signals, monitoring, and audio processing are handled by the
Station Control Module (SCM). The Exciter Modules differ only in the range of operation. Unless otherwise noted,
the information provided in this section applies to all models.
The Exciter board contains the following circuitry:
• Frequency Synthesizer Circuitry – consists of a phase-locked loop and Voltage-Controlled Oscillator
(VCO), generates a modulated RF signal at the transmitter carrier frequency
• RF Isolation Switch – allows the SCM to turn on/off the Exciter RF output signal to the power amplifier
module
• Analog to Digital Converter (ADC) Converter Circuitry – converts the analog Exciter status signals to the
digital format for transfer, upon request, to the SCM
• Local Power Supply Regulation/Filtering – accepts +8V, +10V and +14.2V inputs and provides +5V, +10V,
and +12V operating voltages

Power Amplifier Module Overview
The Power Amplifier (PA) is a forced convection-cooled RF power amplifier. It accepts a low-level modulated RF
signal from the Exciter Module and amplifies the signal for transmission via the site transmit antenna. The output
power is continually monitored and regulated by a feedback and control loop, with a power output control voltage
being generated by the transmitter control circuitry located on the PA Input/Output boards.
Overview of Circuitry
The Power Amplifier contains the following sub-circuits:
• Intermediate Power Amplifier (IPA) – hybrid substrate amplifier stage which accepts low-level input from
Exciter Module, amplifies the signal, and outputs a 0 W to 10 Watt RF signal
• Driver Module (DPA) – the driver module is a single stage hybrid amplifier. I t amplifies the output of the
IPA to a power level between 10 Watts and 35 Watts.
• Dual Device Module (DDM) – hybrid substrate amplifier stage which accepts output from DPA and
provides final amplification. The resulting output of the PA is 75 Watts
• Directional Coupler/Power Detector/Low Pass Filter – couples amplified RF signal to transmit antenna
connector; also generates dc voltages proportional to forward and reflected power for use in TX power
control loop; provides harmonic suppression for the station
• Single Circulator – provides isolation between Power Amplifier output and transmit antenna
• Temperature Sense Circuitry – provides variable resistance signal proportional to heat sink temperature;
signal is monitored by the PA power control circuitry

Functional Theory of Operation
A low-level modulated RF signal (approximately +16 dBm) from the Exciter Module enters the PA Input board via a
coax cable. The signal is input to the IPA and amplified to approximately 0 to 5.5 W (depending on the dc power
control voltage (V_CNTL) from the PA output board). The IPA output is then fed to the Driver PA module and
amplified to greater than 10 Watts (depending on the dc power control voltage). The Driver output is then fed to
the Dual Device Module for further amplification.
The output of the DDM is then transferred to the circulator and then to the harmonic filter/coupler via the PA output
board. The signal then exits from the Power Amplifier Module via an N-type coax connector.
A single circulator is built into the Power Amplifier Module to provide isolation between the PA module and the
transmit antenna.
A thermistor mounted on the PA printed circuit board outputs a variable resistance proportional to the heat sink
temperature. This signal is fed to the power control circuitry on the PA output board, which monitors the signal and
reduces the PA output power (and enables a fan) if the PA temperature exceeds set limits.
A feedback and control loop configuration is used to regulate the PA output power. The Directional Coupler
generates a dc voltage proportional to the PA Module output power. This voltage is fed to power control circuitry
on the PA output board where it is compared to reference voltages to generate a dc power control voltage. The
Station Control Module sends current and power limit signals to a D/A converter (via the SPI bus) to control the
maximum current/control voltage levels. The control voltage is fed to the IPA module where it controls the IPA
output, thus controlling the overall output from the PA Module.
Analog signals from various strategic operating points throughout the PA module are fed to an A/D converter,
which converts them to a digital signal and, upon request by the Station Control Module, outputs the signal to the
Station Control Module via the SPI bus.
For example, the directional coupler generates a dc voltage proportional to the reflected power. This signal is
converted to a digital signal and sent to the SCM. If the sense line indicates an impedance mismatch (high
VSWR), the PA is either cut back in power or shut down completely.

Power Supply Module Overview
The Power Supply is described in this section. The information provided is sufficient to give service personnel a
functional understanding of the module, allowing maintenance and troubleshooting to the module level. Refer to
the service manual for Maintenance and Disassembly/Reassembly Procedures for detailed removal or installation
procedures for all modules in the station.
Over-current conditions on either the 28.6 VDC or 14.2 VDC outputs cause the total supply to shutdown and try to
restart. If the over-current continues to exist, the power supply will ‘hiccup’ until the overload condition is removed,
and will not be damaged by the overload. The 28.6 VDC output is protected by a primary current sense method
such that its current limit point varies depending on the load on the other outputs at the time. The trip point for the
14.2 V and 5.1 V outputs is greater than 115% of the maximum current specified for the outputs. The power
supply recovers automatically after the removal of the overload condition.
The 28.6 V and 14.2 V outputs are protected from continuous over-voltages by detection circuits that cause the
supply to shutdown and then try to restart itself. If the over-voltage condition continues to occur, the supply goes
into a ‘hiccup’ mode of shutting down and trying to restart. If the over-voltage condition is removed, the supply
automatically recovers. In addition, the 14.2 V and the 5 V outputs are protected by crowbar circuits.
An AC Fail detect signal is provided to indicate (when used with battery backup option) that the power supply is
operating from an external dc source rather than the ac mains. This signal is a TTL compatible output capable of
sinking 1 mA, and is routed to the Station Control Module. The active-low state indicates ac operation. For the
nominal 120 VAC operation, the signal is active-high impedance (indicating an ac mains failure) when the ac
voltage is less than 85 Vrms, but more than the minimum voltage that guarantees that all outputs will be in
regulation at full load. For the nominal 240 AC operation, the detect point is less than 170 Vrms but more than the
minimum ac input voltage that guarantees that all outputs be in regulation at full load.
The supply incorporates temperature sense/fan enable circuitry for controlling a 12VDC fan mounted on the
surface of the heatsink assembly. The power supply circuitry senses the internal temperature of the power supply.
When the internal temperature exceeds +60°C (± 5°C), +12 V is enabled at J1–1 to turn on the fan. The +12 V fan
supply is derived from the +14.2 V output. Power to the fan is off when the temperature is below the set limit. The
fan turns for approximately 5 seconds when power is first applied as a diagnostic indicator that the fan is
functional.
The power supply will turn off all outputs when an operational ambient temperature of +80°C (±2°C) has been
reached with the supply operating at any input within its operating input voltage range (dc and ac).
