The ASTRO Conventional
QUANTAR can be set for dual-mode ASTRO VSELP (voice
coder) and analog operation or ASTRO CAI and analog
operation to make your transition to digital as smooth as
possible. This capability allows the station to detect
whether the received call is ASTRO or analog and repeat
it in the appropriate mode. The ASTRO VSELP bunked
station can be configured for either ASTRO VSELP or
analog operation. The ASTRO CAI bunked station can be
configured for either ASTRO CAI or analog operation.
The ASTRO QUANTAR station provides you with cutting edge
technology: ASTRO digital communication. ASTRO can give
you a new perspective on your communications
capabilities. Whether you choose ASTRO VSELP (Motorola's
Digital Technology) or ASTRO CAI (Motorola's digital
solution offering Project 25), it integrates the digital
processing power of tomorrow into features and
flexibility available today. |

QUANTAR
stations can also operate as audio channels in Motorola's
most advanced wide area bunking system: SmartZone. By
routing both clear and coded signals to bunking
subscriber units, QUANTAR stations provide system
flexibility to meet bunking communication needs.

IntelliRepeater™
Operation
A
QUANTAR IntelliRepeater can simply operate as a SmartZone
remote voice channel or perform call processing
activities at a SmartZone remote site while still acting
as a voice channel.
Site space costs are reduced by eliminating a separate
external device at the site to control the calls. The
QUANTAR IntelliRepeater supports such SmartZone features
as Dynamic Site Assignment and Site Variable Density
allowing for infrastructure equipment savings at the
remote sites. Low traffic areas within a SmartZone system
can be covered with bunking technology in a cost
effective manner.
Full-Featured
Fault Tolerance
The QUANTAR IntelliRepeater has the capability to
transfer call processing capabilities to another
IntelliRepeater at the site without disruption in active
calls and minimal change in system access time.
IntelliRepeater operation provides continuous bunking
communications and retains all APCO 16 features at an
individual site.

Enhanced Reliability
and Flexibilty
Continuous
Duty Operation
The station is designed for continuous duty operation
and may be operated at full-rated power, exceeding FCC
specifications. Reliability is increased by providing
longer station usage for the most demanding
communications systems.
State-of-the
Art Digital Receiver
The QUANTAR station's receiver module has been
completely redesigned to provide flexible system design
with easy installation and adjustment.
- The
receiver is functionally independent from the
transmitter allowing implementation of crossband
conventional operation.
- User-programmable
channel spacing to 12.5 kHz operation simplifies
station migration to narrow band channelization
plans.
- To
reduce station installation and alignment time,
only the conveniently frontmounted preselector on
VHF and UHF stations requires tuning.
- Synthesized
frequency generation allows for economical and
easy-to-implement frequency changes.
- Truly
wide-band receiver-4 MHz bandwidth on VHF and UHF
stations allows for a greater range of
frequencies.
Advanced
Transmitter Design
The QUANTAR station's transmitter design meets and
exceeds major global intermodulation specifications for
stations placed at crowded antenna sites. Electronic
adjustment of deviation and power improves performance
and lowers cost by reducing manual tuning adjustments at
installation. Modulation sensitivity and power output are
adjusted on a per channel basis to provide improved
performance in a variety of system configurations.
QUANTAR station's transmitter is equipped with an
internal wattmeter for ease in measuring transmit output
power.
Built-in
Single Circulator
The QUANTAR station has a single circulator included
in every station to improve reliability by protecting
against antenna mismatches and to aid in the reduction of
interference caused by equipment at crowded sites.
Truly Compact Station
The entire QUANTAR station fits in a 5 rackunit-high
card cage weighing only 55 Ibs. Motorola's
state-of-the-art technology allows efficient use of site
space since additional equipment can be installed in the
same area, giving reduced site rental costs and improved
system aesthetics.
Modular
Mechanical Design
The QUANTAR station's card cage modules are easily
removed and replaced for station upgrades or servicing.
These Field Replaceable Units (FRUs) provide prompt
communications recovery. System upgrades are easily
performed by replacing a systemspecific functional module
or in some cases by simply loading new software. Both
short term and long term cost savings are realized in
installation, system maintenance, and upgrades.
Switching
AC Power Supply
Improvements in power supply technology yield a
reliable, lightweight, switching power supply. The power
supply can operate over a wide range of main voltages
(90-280 VAC) and frequencies (47-63 Hz) anywhere in the
world without modifications. Voltages are adjusted
automatically to eliminate the chance of failure due to
improper installation.

Simplified
Service and Installation
Convenient
Connection Access
Routine service ports are all located at the front of
the station. All primary installation connectors are
located on a single backplane accessed through the rear
of the station. Installation and maintenance can be
performed quickly, minimizing set-up time and maintenance
costs.![](med3.jpg)
Programming
The QUANTAR station is based upon a flexible software
design that allows programming and alignment through a
personal computer and appropriate software. The
user-friendly software simplifies the process of
adjusting station characteristics, thereby minimizing
station downtime.Self-Test Diagnostics
On power-up and during operation, the QUANTAR station
automatically initiates selftests without interfering
with communications. The station conditions can be
readily determined by viewing the light emitting diodes
(LEDs) on the module front panels providing quick and
easy visual appraisal of station status. Station alarm
messages and self-designed test results are logged and
accessed through the Radio Service Software. Maintenance
information is at your fingertips.

Options
ASTRO
9.6 KBPS Modem
The ASTRO 9.6 kilobit duplex modem allows the
interconnection of ASTRO fixed equipment via telephone
lines. In order to minimize the number of phone lines
required in any system, the ASTRO modem allows for the
processing of both digital and analog audio. The signal
generated by the modem can also pass through standard
narrowband microwave multiplex channels. The modem is
designed to fit internal to the station chassis,
eliminating the need for additional housing space.
Triple
Circulator
This option is recommended for RFcongested
transmitter sites where added isolation protection is
required. It can be mounted in a rack or cabinet.
Battery
Revert for Switching AC Power Supply
Battery back-up is offered as an option to provide
uninterrupted station service in the event of a site
power failure. The station operates on a single battery
voltage in battery revert mode. The station aerates power
as the battery voltage drops. Line supplies charge
batteries independent of the power amplifier voltage. The
battery revert option includes several new features as
standard: Voltage Adjust, Battery Temperature Adjust,
Battery Watchdog, Battery Overvoltage Protection, Battery
Connection Protection, and Low Voltage Disconnect. These
features help provide optimal charging voltage to the
battery, lengthen the battery's life, reduce maintenance,
and protect batteries from improper installation and
voltage overcharging.
DC-DC
Convertor
The DC-DC convertor has the ability to utilize 12 (20
and 25 watt models only), 24, 48, or 60 VDC sources.
These sources may be positive or negative ground. The
wide range of voltages allows the station to utilize site
power sources which may be more economical or reliable
than the available AC power source.
