1 About the DXL8000
The DXL8000 Short-Haul Microwave System (DXL8000) is a cost-effective, high performance,
highly reliable, flexible, and compact microwave link for short haul applications. The DXL8000
6 to 23 GHz Short Haul Radio is also a split-mount, digital, duplex microwave radio designed
for Studio to Transmitter, Transmitter to Studio and “last mile” point to point applications. The
DXL8000 delivers aggregate data rates up to 170 Mbps at 64QAM modulation (license
dependent). The DXL8000 consists of the Indoor Unit (IDU) and an Outdoor Unit (ODU) as
shown below:
The DXL8000 provides high-quality digital transmission under a Single Carrier QPSK/QAM
Modulation (SCM) scheme and is available in simplex or duplex and Hot Standby (1+1), using
the Hot Standby protection switch. The DXL8000 digital microwave transceiver can support
video and data transmissions.
• The DXL8000 is a digital mode transceiver that accepts multiple transport data streams
or an external 70 MHz digitally modulated IF signal. The input data streams are
multiplexed and are modulated onto the IF signal using Single Carrier QPSK/QAM
Modulation. Then the modulated IF signal (or external IF signal) is up-converted to the
final radio frequency (RF) required and is transmitted through the antenna.
• The DXL8000 transceiver also receives RF signals from the antenna and down-converts
the RF signals to a 70 MHz IF. The original data streams are demodulated using Single
Carrier QPSK/QAM Demodulation. IF output is also available for connection to an
external demodulator or test equipment.
The DXL8000 supports from 1 – 4 independent, user selectable transport streams, and includes
Web browser management Interface to optimize transmission parameters for maximum spectral
efficiency. Transport stream options include ASI, SMPTE 310M, in support of ATSC, DVB-T,
ISDB-T BTS and DS3 / E3, 100BaseTX Ethernet, RS232, RS485 and T1/ E1. The advanced
digital modulator includes Viterbi error correction for ultra-robust performance under adverse
path conditions, while the adaptive equalizer at the receiver automatically compensates for
multipath errors.
DXL8000 User and Technical Manual About the DXL8000 1-1

The DXL8000 is designed to install, setup, and manage easily. The split mount design enables
the use of economical coaxial interconnects between the Indoor Unit and the rooftop or tower
mounted Outdoor Unit. The radio’s advanced control processor with embedded web server
provides a rich set of control and configuration options both locally, and remotely, over a secure
IP connection.
All operating parameters are monitored by the control processor which immediately reports
alarm conditions via the graphical interface and relay contacts. Alarms may be customized to
suit user preferences, and a wayside serial port is included for service channel support.
The DXL8000 Short Haul Radio delivers industry leading throughput performance, an extensive
range of interface options and advanced configuration and control to meet broadcasters’
requirements and future growth plans.

DXL8000 User and Technical Manual Installing the DXL8000 2-1

An AC power cable comes with each DXL8000 IDU. The DXL8000 IDU supplies -48V DC
power to the Outdoor Unit (ODU) from the rear panel ODU DC ON COAX Type N connector.
WARNING - RF Power Hazard
WARNING The unit has high levels of RF power. Exposure to RF or microwave
power can cause burns and may be harmful to health.
• Remove power from the unit before disconnecting any RF cables and before inspecting
damaged cables and/or antennas.
• Avoid standing in front of high gain antennas (such as a dish antenna) and never look
into the open end of a waveguide or cable where RF power may be present.
The following guidelines for safe operation were derived from OET bulletin 65, August 1997, as
recommended by the Federal Communications Commission (FCC).
The DXL8000 was designed to provide services to licensees under 74 CFR, subpart F,
television broadcast auxiliary stations, and under 101 CFR, subpart H, private operational fixed
point-to-point microwave service. This unit, operated without an antenna, will not create RF
energy exceeding 1.0 mW/cm2, the FCC limit for exposure. Once connected to an antenna, the
potential for harmful exposure will be greatly enhanced.
In this situation, a certain distance from the radiator is to be maintained. Calculations need to be
Permissible Exposure (MPE) limit.
Calculations provided are for common antennas often utilized in point-to-point applications. The
following formula used is that suggested by OET 65.
2.2.2 Calculating MPE
EIRP =P * [10(G / 10)]=(AntiLog of G/10)*P
P= RF power delivered to the antenna in mW
G= Power gain of the antenna in the direction of interest relative to an isotropic radiator
R= distance to the center of radiation of the antenna in centimeters
S= MPE in mW/cm² (milliwatts per square centimeters)
Conversions
dBi to numeric gain = AntiLog (dBi/10) Feet to centimeters = Feet *30.48
Centimeters to Feet = cm *.0328
4 π= 12.57
User Input
RF power delivered to the antenna = Watts
Antenna gain (referenced to isotropic antenna) = dBi
Distance from the center of radiation = Feet

2.2.3 Grounding the DXL8000
CAUTION Be sure the equipment grounding follows applicable electrical codes.
Never modify a grounded power plug to connect to an ungrounded
receptacle.
For safe operation, all equipment must be properly grounded.
• Make the ground wire as short and straight as possible.
• Connect the DXL8000 IDU ground lug to the common ground on the installation.
• Connect the common ground to site ground.
2.2.4 Ventilating the DXL8000
CAUTION Temperatures inside a closed mounting area can be significantly higher
than the ambient temperature. Always allow adequate ventilation.
If possible, install components in a climate-controlled area. Allow adequate airflow around the
equipment. Exhaust air from the rack should be circulated and not trapped in a closed space.
2.2.5 Protecting the DXL8000 from Moisture

2-4 Installing the DXL8000 DXL8000 User and Technical Manual

2.2.6 Routing Cables
Wiring is affected by temperature, humidity, and vibration extremes. You should do the following
installation.
CAUTION Power supply cords and cables must be protected. Do not run cords
where they can be stepped on. Protect cables against pinching and
chafing. Pay special attention to locations where the cables enter or exit
an enclosure or make a sharp bend.
• Secure all cables at close intervals along their entire lengths.
• Protect cabling with added sheathing or padding anywhere cabling passes through a
hole or lies against an obstruction.
• Provide flex relief at any location where the cable must change direction sharply, to
maintain a smooth bend and prevent kinking.
• Provide strain relief at each connector to absorb any pulling forces on the cable and
prevent damage to the connector.
• If long lengths of cable are required, you may need a UHF amplifier or gain block.
Contact Vislink for specific cable types and lengths to use in your application. For specific cable
types and lengths to use in your DXL8000, contact Customer Support; see Section 1.3, About
the Outdoor Unit.
2.2.7 Power Requirements
The DXL8000 operates on 115/230 VAC, 50/60 Hz and - 48 VDC. Fuse ratings for the AC and
DC power sources are as follows:
Operating Voltage Fuse Rating Power Consumption
230 VAC, 50/60 Hz 1.0A, 250V AGC, Fast Blow
120W maximum
115 VAC, 50/60 Hz 2.0A, 250V AGC, Fast Blow
-48VDC,1.2 A, 3 A, Slow Blow 57.6 W
CAUTION Ensure that the power being supplied matches the power required by
the equipment. You can find power ratings for equipment on a rating
plate, usually on the rear panel. Ensure that the electrical supply is
protected by over-current protection devices as required by the
applicable electrical codes. If necessary, consult a licensed electrician.
DC Power Operations
When you are operating an unprotected Transmitter, Receiver and ODU system your DC input
should incorporate a properly grounded, 1.2 A, 57.6 W regulated power supply. It is crucial that
overload, over voltage and over temperature protection that shuts down the power supply
should be built in. The incidental increase in amperage should shut down the power supply and
then restore power upon recovery to avoid equipment damage.
For a protected system, the 48 VDC is supplied by the DXL Hot Standby switch. For more
information, refer to the DXL8000 Hot Standby Protection Switch User Guide.
