INTRODUCTION
The 5720 series product line is designed with the user in mind.
With the implementation of modular component technology, it is
no longer necessary to perform component level repairs at the
site. By simply replacing an entire module the unit is quickly ready
to return to normal operation.
The unique hinged front panel eliminates the need to remove the
unit from the cabinet for routine inspection and maintenance.
5720 series products can also be upgraded just by making a few
simple adjustments and changing specific modules.
With additional features such as ability to connect to external am-
plifiers, change output power, and an optional spectral shaping fil-
ter, 5720 series products are versatile as well as cost effective.
This manual covers all power levels of the 5720 including the 5721,
5722, 5723, and 5724.

SYSTEM
Unpacking
Axcera certifies that upon leaving our facility all equipment
was undamaged and in proper working order. It is impera-
tive that all packages be inspected immediately when re-
ceived to verify that no damage occurred in transit to the
site.
·Inspect all packages for exterior damage and
make note of any dents, broken seals, or
other indications of improper handling.
·Carefully open each package and inspect the
contents for damage. Verify that all materi-
als are enclosed as listed on the packing slip.
Report any shortages to Axcera.
·In the event any in transit damage is discov-
ered report it to the carrier. Axcera is not
responsible for damage done by the carrier.
·If the equipment is not going to be installed
immediately, return all items to their original
packaging for safe storage.
·Save all packing material for future use. If
equipment is ever removed from the site, the
original packaging will ensure the safe trans-
port of it. Keep at least one copy of all docu-
mentation including this manual at the site in
a safe place.
Installation
All 5720 series products are designed for simple installation
with comprehensive instructions. Expensive test equipment
is not required to keep a system operational, installation,
and set up. Prior to installing the product review the check-
list that follows.

· Is the space provided for equipment racks suffi-
cient ? Will an additional devices that extend out
above or to the side of the unit have sufficient
clearance space ? Refer to the system custom rack-
ing plan for detailed specifications.
Input Connections for Analog Operation:

connector located on the rear of the tray.
Connect either the Baseband Balanced Mono Audio Signal Input
to J11, a 600 ohm 3 terminal block connector located on the
rear of the tray, or the Unbalanced Composite Stereo Audio Sig-
nal Input to J3, a 75 ohm BNC connector also located on the rear
of the tray.
Input Connections for Digital Operation:
Connect the Digital IF Signal Input to J14, a 75 ohm BNC connec-
tor located on the rear of the tray.
NOTE: For connections using Scientific Atlanta and Pac-Mono
scrambling, refer to that section which follows.
Output Connections for Typical Operation:
Connect RF Output of the tray at J8, a 50 ohm N connector,
located on the rear of the tray, to the designated Channel Com-
biner or Spectral Shaping Filter for your system.
Check that CB1 the AC circuit breaker, located on the rear of the
tray near the AC input Jack, is Off.
Connect the AC power cord the J1 on the rear of the tray and
the plug end to an appropriate AC outlet.

System Description
5720 series transmitters are available in various power levels from 2.5 to 100
watts average power or 10 to 230 watts peak analog. Units can be factory set to a
specific channel in the 2076-2700 MHz range. QAM signals up to M=256 as well as
NTSC and PAL modulation can be processed by the unit. A center frequency of
either 44 MHz or 36 MHz can be set at the factory prior to shipment.
All 5720 series transmitters are compatible with SCADA . Using SCADA allows
operators to monitor and control systems from remote locations.

Digital / Analog
MMDS Transmitter
Compatible with digital and analog
modulation including 256 QAM, NTSC, and
PAL
Broad power range of 2.5 to 100 watts
average digital power and 10 to 280 watts
peak sync analog power
Modular design simplifies installation, field
service, and upgrades
Hot-replaceable modules improve system
availability
Redundant design enables system to stay
on the air even if an amplifier module fails
Broadband amplifier design simplifies repairs
and minimizes inventory
High efficiency GaAsFETs reduce operating
expenses and save space
User friendly diagnostics with English,
Portuguese, and Spanish text
Adjacent and non-adjacent channel
combining systems available
SNMP Network Management System
Automatic and manual backup systems
available
The new 5720 series transmitters are the
result of a global design strategy. All aspects
of the product design, from frequency range
to modularity, reflect a long term commitment
to our global partners. These transmitters
provide a platform which allows for simplified
installation, field service and system
upgrades. Axcera has taken significant steps
to reduce system operating costs and size,
while providing a solution that works for
either analog or digital transmission.
Compatible with Digital and Analog Modulation
The 5720 series transmitters are compatible
with digital and analog modulation including
256 QAM, NTSC, and PAL. An internal NTSC/
PAL modulator is available to save rack
space.
5720 Series Provides Broad Power Range
Operators can select from 2.5 to 100 watts
of average power, or 10 to 280 watts of peak
sync analog power. Transmitters can be set
for any channel in the 2076-2700 MHz
frequency range.
Modular, Reliable Design
Modular design simplifies installation, field
service, and upgrades. Modulator, IF, LO/
upconverter, amplifier, power supply, and
transmitter control modules can be replaced
in seconds. Each slide into a backplane with
plug-in connectors. Surface mount technology
improves system MTBF.
5720

High Efficiency, Broadband Amplifiers
Axcera has selected the newest, most efficient
GaAsFETs for the 5720 series. Redundant
amplifier modules enable the system to stay on
the air in the event of a failure. Amplifier
modules are hot-replaceable so they can be
removed and installed while the system is
operating. Amplifiers are tuned broadband to
simplify repair and reduce spares inventory.
Feedforward and advanced equalization
techniques are employed to meet
the FCC spectrum mask for out-of-band
performance specifications while minimizing power
consumption.
Compact Size
A complete 31 channel system for 50W peak
operation fits into just four racks. Even the new
8770 Filterplexer combiner can be configured for
eight channels per rack. The 8770 Filterplexer is
available for both adjacent and non-adjacent,
analog or digital applications. Adjacent combining
reduces the system purchase price because only
one antenna and waveguide run are required.
Anytime, Anywhere Communication and Backup
With the SCADA system operators have real time
remote and local control of the transmitter
system and site. Graphic user interfaces simplify
integration with Windows or UNIX based SNMP
network management systems. Axcera ’s
automatic backup system permits a scaleable
number of channels to be backed up per agile
transmitter.
Turnkey Solutions and 24-Hour Support
At Axcera our transmitters, amplifiers, and
channel combiners are manufactured and tested
as a system to achieve the ultimate in
performance and value. Our system integration
group can document, install, and commission
your entire digital MMDS transmitter system.
Axcera field engineers are available to oversee
analog to digital system conversions and provide
on-site training. We offer a comprehensive range
of support services that are designed to keep
your transmitter system producing revenue year
after year.
