MTR3000 Overview
The Motorola MTR3000 Base Station/Repeater provides a modular, flexible analog and digital
station design for today's communication systems and for the future. The station is available for
use in Analog Conventional, Digital Conventional (MOTOTRBO), MOTOTRBO Capacity
Plus Trunking and Connect Plus (UHF Only) multi site trunking configurations.
When configured for analog operation, MTR3000 can either be configured as a base station or
as a repeater. As a 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
as a base station, MTR3000 is designed to operate with most existing analog systems.
When configured for digital operation, the base station/repeater offers additional services. The
digital base station/repeater operates in TDMA mode, which essentially divides one channel
into two virtual channels using time slots; therefore the user capacity is doubled. The base
station/repeater 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.
10
Note: When configured in Digital Mode, MTR3000 can only be used as a repeater.
At any given time, MTR3000 either operates as a digital repeater or as an analog
repeater.
The MTR3000 base station/repeater 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. The description of the FRUs is as follows:
• The Receiver FRU is a dual heterodyne receiver which receives the RF signal from
the subscriber’s transmitter. It then converts the resulting final intermediate
frequency (IF) from an analog signal to that of a digital word. Finally, the receiver
delivers the digital word, via the data bus, to the SCM for demodulation.
Additionally, the receiver also provides its own metering and diagnostics via
software, as well as a self-contained calibration (no field tuning needed).
• The Exciter FRU converts a two-port base band data signal, sent over the data bus
from the SCM, to an analog signal representation. The analog signal then modulates
a low power RF transmitter carrier that is generated by the exciter. The low power
modulated RF carrier is then amplified and delivered to the PA for further
amplification. The Exciter and PA constitute the transmitter of the MTR3000.
Additionally, the exciter also provides its own metering and diagnostics via
software, as well as a self-contained calibration (no field tuning needed).
• The heart of the SCM FRU is that of two Texas Instruments OMAP series
processors, with each OMAP containing an ARM Host and a C55 DSP processor.
One of the two OMAP processors is dedicated to the receiver DSP operations, while
the other OMAP provides for all other functionality, which includes the transmitter
functions. In general the SCM provides for the entire coordination of the base
station/repeater functions, but more specifically, the SCM provides for the following
functionality:
‐ Contains and runs the preloaded base station/repeater software.
‐ Manages inbound and outbound RF and Audio traffic.
‐ Provides external speaker and microphone ports (analog only)
‐ Provides an on-board USB port for local configuring, alignment and
diagnostics via the following applications:
o Customer Programming Software (CPS),
o Tuner application
o Repeater Diagnostic and Control (RDAC) software.
‐ Provides an Ethernet port for IP site connectivity and remote RDAC.
‐ Provides GPIO connectivity for 3
rd
party controller interfaces.
‐ Provides analog base station audio connectivity.
‐ Data and Control to the receiver
‐ Data and Control to the exciter
‐ Control of the PA’s set power
11
‐ Generates the internal station frequency reference.
‐ Provides control of the front panel status indicators.
• The PA FRU amplifies the low level modulated RF signal from the exciter module.
It then delivers the amplified signal to the transmitter antenna port at the rated power
of the base station/repeater, or less if the customer desires, for transmission to the
subscriber’s receiver. In addition to its primary task of amplification, the PA
provides the following hardware functions for the base station/repeater’s:
‐ Harmonic attenuation
‐ Intermodulation attenuation (IMA) suppression
‐ VSWR detection
‐ RF power control (primary means).
‐ Self contained cooling fan and control circuit
‐ Diagnostics
‐ Power rollback for temperature, VSWR, and voltage
‐ Self-Contained calibration (No field alignment for MTR3000 PAs only)
• The PS FRU provides DC power to the receiver, exciter, SCM, PA, and select third
party controllers via one or more of the three DC output taps; 28.6VDC, 14.2VDC,
and 5.1VDC. It can also provide auxiliary power to a number of third party
controllers. Additionally, it can operate in three different input modes:
‐ AC Input Only
‐ DC Input Only
‐ AC with Battery Revert
In addition to providing power to the noted FRU’s and controllers, the PS also
provides for the following:
‐ AC Failure detect signaling to the SCM
‐ Output over-current protection for all three outputs
‐ Self contained cooling fan and control circuit
‐ Thermal shut down if the environmental temperatures exceed the cooling
capacity afforded by the fan.
‐ Further details can be found in the individual “Theory of Operation” sections
of the respective FRUs.
• The Wireline FRU provides the connection to an analog audio source/sink (such as
a console) to the MTR3000 Base Station/Repeater. Specifically, the Wireline board
provides for the following:
Tone Remote Control
DC Remote Control
4-wire balanced audio connection
2-wire balanced audio connection

MTR2000 MOTOTRBO UPGRADE (Non-RTTE countries only)
Overview
The FRU architecture of the MTR30000 Base Station/Repeater allows the ability to upgrade an
existing MTR2000. An upgrade requires that the MTR3000 station core module (exciter,
receiver and station control module) be used to replace the MTR2000 exciter, receiver and
control module. The upgrade allows a customer to move from an analog platform to a digital
platform and increase their call capacity with the MOTOTRBO technology.

MTR2000 MOTOTRBO Upgrade Specs
When the MTR2000 is upgraded to an MTR3000, the specifications of the new components
(exciter, receiver and station control module) are the specs of the MTR3000 modules. (See
component specification tables.)
NOTE: The transmitter dynamic RF output power range will remain the same as it was
prior to the upgrade.
15
MTR2000 MOTOTRBO Upgrade Installation
Upgrading an MTR2000 is a simple procedure. Depending on the proficiency of the technician
the hardware upgrade takes approx 15 minutes to complete per Base Station/Repeater.
Additional time will be required to program the station with the Customer Programming
Software (CPS) to the customer specific configuration. Before beginning the upgrade,
document the current code plug settings of the MTR2000, as they will need to be manually
entered into the MTR3000 CPS.
Note: The codeplug file format of the MTR2000 is not compatible with the codeplug file
format of the MTR3000, so manual entry of the codeplug configurations will be
required.
Compatibility
The following charts identify the system types, stations, and controllers that are compatible
with the MTR3000. Table 5 and Table 6 outline a direct feature comparison between the
MTR3000 and the MTR2000. It is imperative that the differences between the two stations are
understood when an MTR3000 is to be purchased for use in an analog system, as not all analog
features that were offered with the MTR2000 are available with the MTR3000. Furthermore,
the base station audio and control interface on the backplane has changed between the
MTR3000 and MTR2000 stations. These interface differences are noted in the “Adding
MTR3000 and/or Upgraded MTR2000 stations to MTR2000 sites” section of this manual.
Additionally, the MTR3000 platform offers a MTR2000 MOTOTRBO UPGRADE for existing
high-power UHF MTR2000 stations. When a MTR2000 station has employed the
MOTOTRBO Upgrade Digital Kit, the upgraded MTR2000 station will provide all digital
functionality that a factory new MTR3000 provides. Analog features offered in an upgraded
MTR2000 station are identical to that of a factory new MTR3000, however, there are subtle
differences in the analog connectivity at the J7 backplane connection between an upgraded
MTR2000 station and that of a factory new MTR30000 station. These differences are noted in
the “Adding MTR3000 and/or Upgraded MTR2000 stations to MTR2000 sites” section of this
manual.
Note: Since analog features will be lost with respect to the non-upgraded MTR2000, it is not
recommended to purchase a “MOTOTRBO Digital Upgrade Kit” for the MTR2000 if
one expects to operate the upgraded MTR2000 in analog mode. Upgrading the station
and operating in analog mode may be a temporary configuration while migrating the
subscribers. See Table 7 for specific configurations that are upgradeable.
The MOTOTRBO Upgrade Kit consists of the following individual items:
• MTR3000 Exciter FRU
• MTR3000 Receiver FRU
• MTR3000 Station Control Module FRU
• MTR3000 Front Bezel
16
• Preloaded MOTOTRBO SW
• TORX screws – T20 bit size required. (Used to assemble the three FRUs to one
another)
• MTR3000 FCC upgrade label (Use to cover the MTR2000 FCC label located on the
backplane)

Considerations before beginning a migration plan
The purpose of an MTR2000 MOTOTRBO upgrade is to allow users to migrate to
MOTOTRBO digital without having to purchase an entirely new station. When upgrading to an
MTR3000, use the following chart to ensure features and/or functionality is supported.

Note: An Upgraded MTR2000 can be used in analog mode. However, since some analog
functionality would be lost in this transition, this application would be best applied
to a customer who intends to migrate to MOTOTRBO at some time in the future.

SPECIFICATIONS
Specification Definitions
Listed alphabetically are the definitions of some of the specifications described above.
Information on whether the preferred specification would be smaller or larger is also given.
1) Adjacent Channel Power Ratio (Decibels/ dB): A measure of the level of undesired
transmit signal that falls within the adjacent frequency channel. Often this is limited
by the modulation type rather than hardware or software. A larger number is better.
2) Adjacent Channel Rejection {Selectivity} (Decibels/ dB)–Ability of the receiver to
detect the desired signal, while rejecting signals on adjacent channels. The benefit is
less interference. The preferred specification is larger. Effective system performance
may be limited by the interfering subscriber units’ transmitter noise or modulation
characteristics
3) Bandwidth: As it applies to T-T or R-R (Megahertz/ MHz)–The maximum
frequency separation from the lowest frequency to the highest frequency without
degradation of specifications. The preferred specification for multi-channel base
stations/repeaters should be wide enough to include all the channels that are used,
depending upon the application.
4) Bandwidth: As it applies to T-R Spacing (Megahertz/ MHz)–The specified
frequency separation between the transmitter and receiver is band dependent. The
preferred specification is generally smaller, although it depends upon the specific
site requirements.
5) Bit Error Rate Floor (%): A measure of the receiver’s ability to detect and decode
strong signals accurately. A small percentage is better.
6) Conducted Spurious Emissions (dBm): Undesired receiver output signals (on the
antenna port). The benefit is reduced interference with other base stations/repeaters
nearby. The preferred specification is a more negative number.
7) Co-Channel Rejection (Decibels/ dB): Ability of the receiver to reject on channel
interference. This specification is usually determined by the modulation type. A
smaller number is better.
8) Electronic Bandwidth: Operating range that can be obtained without any mechanical
adjustments, such as tuning screws. Larger number is better. Full bandwidth is best.
9) Emissions Designator: An FCC designator describing bandwidth and modulation
type.
10) Frequency Stability (+/-% OR parts per million/ppm OR parts per billion/ppb): The
ability to stay on the assigned frequency over a temperature range of -30° to +60°C.
The benefit is increased coverage, less interference and reduced background noise.
The preferred specification is smaller, which implies a greater stability.
11) Harmonic Emissions Attenuation (Decibels/dB): Similar to spurious outputs
(described below); multiples of the frequency of the final power amplifier
(transmitter). The benefit is reduced interference to nearby base stations/repeaters.
The preferred specification is a larger number.
12) Intermodulation Attenuation (Decibels/ dB): Reduces transmitter intermodulation by
preventing undesired signals from entering into the transmitter's PA. This is
26
accomplished by using circulators or isolators. The preferred specification is larger.
This specification is especially important at dense sites.
13) FSK Error (%): A measure of the transmitter’s ability to accurately produce a
digitally modulated signal. A smaller percentage is better.
14) Receiver Intermodulation/IMR (Decibels/ dB)–Mixing of undesired signals which
interferes with the desired signal. This is important if the R-R bandwidth is large.
The benefit is less interference. The preferred specification is larger.
15) Sensitivity (Microvolts/µV or dBm)–The ability of the receiver to detect and
amplify weak signals. The benefit is increased coverage. 12 decibels SINAD is the
threshold for intelligible analog voice communications. The preferred specification
is smaller. 5% bit error rate is the threshold for intelligible digital voice
communication.
16) Signal Displacement Bandwidth (Off-Channel Acceptance) (kHz)–The amount the
signal can be off the tuned frequency and still be received. The preferred
specification is larger and must be at least as good as the frequency stability of the
transmitting subscriber units.
17) Spurious Emissions (Decibels/ dB)–Undesired transmitter output signals. The
benefit is reduced interference with other base stations/repeaters nearby. The
preferred specification is a larger number.
18) Spurious (Image) Response (Decibels/ dB)–Ability of the receiver to reject certain
types of undesired or interfering signals related to the operating frequency. The
preferred specification is larger.
For analog FM, TIA603D standards and methods are used unless otherwise noted for analog
specs. Specifications regarding digital modulation use TIA102 methods.
