CHAPTER 2 Norsat
NewsLink
Overview
The Norsat NewsLink is a portable sat ellite terminal th at provides broadc ast
quality MPEG-2 vid eo transmiss ion, communic ating with a centr al teleport or
HUB station. Its design allows it to be carried by two p eople, with an in field
deployment and setup time by a camera operator of less than 15 minutes.
Features
System Operation
The Norsat NewsLink:
• Allows for quick on-location arrival and setup time, in order to begin
broadcasting for major int ernationa l news events before a typic al flyaway
system could arrive and be operational
• Provides more flexibility to the on-site news team as to the location of
where the uplink s ystem can b e operated, as opposed to traditiona l flyaway systems which require a fixed major center for the duration of the
transmission
• Allows for quic k tran sp ort due to i ts por tability, thus enabling ne ws te ams
to easily cover sma ll live international events or reach a l ocation that is
typically not considered by conventional flyaway operations
A block diagram of the Norsat NewsLink is given in Figure 1 on page 4.

Satellite infor mation may be setup prior to on-location arrival, in addition to
Transmission Profile(s) that detail the sy stem settings, includ ing the creation
of a transport stream and setup of video and audio PIDs.
The Norsat NewsLink is enclosed in thre e cases; the Base band/IF case and
the two Antenna/RF case s: RF and Antenn a Unit case, Model 32 00-RF, and
Accessories case , Model 3200-AC. Once the news team is on location, the
antenna is removed from the case and assembled; the Baseband unit may be
removed from the carrying case, or may be in a shock mounted chassis. After
the antenna is assembled, it is connected to the Baseband/IF unit. The Norsat
NewsLink is now ready to be configured.
The antenna must be al igned to the proper elev ation, azimuth and polar ization for the desired satellite transponder. Using the Norsat NewsLink graphical
user interface (GUI), the user selects the desired satellite and polarization
from which the global position ing system (GPS) deter mines the curre nt location of the antenna. Once this is obtained the proper azimuth, polarization and
elevation are calculated.
The polarization is set using the indicator located on the fe ed assembly. A
compass located on th e base of the antenna indicate s the current azimuth,
and an inclinometer lo cated on the back of the d ish indicat es the curre nt elevation. The azimuth and elevation values are set to the values indicated in the
Norsat NewsLink GUI. Then, while watching the signal strength meter, the
antenna is fine tuned in order to obtain an optima l si gna l stren gth . In addition ,
the Norsat NewsLink G UI contains a spectrum analyze r, which can also be
used to align the antenna and verify that locked onto correct satellite.
After the antenna is pr ope rly al ign ed, the ca mera and external equipment are
then connected to the Baseband unit.
N
OTE This step is done after an tenna align ment as the Base band/IF uni t may need
to be moved.
Using the Norsat NewsLin k GUI, the previously configured Transmiss ion Pro-
file is selected.
The satellite operator is now called to obtain approval for transmis sion. The
user indicates to the satellite operato r the selected sate llite and transponder
(frequency and polariza tion) they wish to transmit on. When author ization is
given by the satell ite operator, the news crew brings up a continuous wave
(CW) signal at the requested power setting. This setting will be adjusted to the
proper levels a s indicated by the satellite operator. The polarization will then
be checked usin g a cross-pol signal. The satellite opera tor will then request
that the news crew turns modulation ON at low power. The power level is
gradually increased unti l t he m axi mu m power level is reached. O nce prop er ly
set, the satellite oper ator will give the news team auth orizati on to beg in news
transmission.

CHAPTER 3 Norsat
NewsLink
Cases
The cases that house the Norsat NewsLink Antenna/RF and Baseband/IF
units are weatherproof, and there should be no water penetration when all
winglocks are properly secured.
The cases will provide sh ock and vibration protection du ring storage, transport and, in the case of the Baseband/IF unit, operation. However, care
should be taken when handling the cases in consideration of the enclosed
electronic equipment of the Norsat NewsLink.
The Antenna/RF unit i s stored in two case s, the RF and Antenna Unit case,
Model 3200-RF, and the Accessorie s case, Mo del 3200-AC; re fer to Figure 2
on page 8. The Baseb and/IF unit is st ored in one case; r efer to Figure 3 on
page 8.
The Antenna/RF cases are equipped with a press ure relief valve that equa lizes the pressure inside and outside the case. This relief is provided automatically should the pressure difference become too large, thus preventing the
case from exploding due to extreme differences in atmospheric pressure.
Alternatively, the case may be under a vac uum and hard to open . The valve
can also be depressed by the user to manually equalize the pressure.
N
OTE This procedure i s necessary befor e opening a case to e nsure that unlo cking
the latches on the c ase is bo th safe and easy; refer to “ Opening th e RF Unit
Case” on page 22 for instructions.

Antenna
Transceiver
Page 11
The antenna consists of the di sh reflector, feed horn, OMT, flex waveguides,
boom arm with built in rigid waveguide and mechanical support structure. The
mechanical support structure positions and points the antenna reflector in
order to aim the antenna beam at the required satellite.
The Transceiver consists of block upconver ter/transmitter, a 15 W or 25 W
solid state power amplifier (SSPA) and a low-noise block (LNB) downconverter. The block upconverter converts the incom ing L-band (950- 1450 MHz)
signal to Ku-band (14 -14.5 GHz). That signal is then amplified by the 15 W or
25 W SSPA, and fed through the antenna. Thus, after converting to dBW, the
system provides a maximum effective isotropic radiated power (EIRP) of 53
dBW for the 15 W SSPA and 55.5 dBW for the 25 W SSPA.
The LNB then down-converts the down-linked Ku-band signal:
• A: 11.7 - 12.2 GHz
• B: 12.25 - 12.75 GHz
• C: 10.95 - 11.7 GHz
to an L-band signal:
• A: 0.95 - 1.45 GHz
• B: 0.95 - 1.45 GHz
• C: 0.95 - 1.7 GHz
Peripherals
The peripherals aid in antenna pointing and include the following:
• Compass: used for azimuth settings
• Inclinometer: used for elevation settings
• Level: used to ensure antenna is level
• Interface/Indicator: interface for IFL connections, indicates when the
transmitter is on and indicates the receive signal strength
• Ku-L Block Down-converter
Compass
The fluxgate compass has a di gital display with an accuracy of degree.
The compass is mounted on the base of the antenna in order to accurately
indicate the azimuth of the antenna beam. T he compass is powered by 12 V
supplied from the Bas eband/IF unit. It is connected to the Interface Indica tor
unit by a flying lead with a multi-pin connector.
As with all fluxgate compass es, best perfor mance occur s when the compass
is level and ther e is no ferrous metal ob jects a round. To compensate for both
hard and soft magnetic inter ference, the compass should b e calibrated. The
compass is calibrated at the factor y, however, it is beneficial to re-calibrate it

Inclinometer
at new locations or if the ma gnetic environment/interface cha nges. Refer to
“Compass Calibration” on page 89 for instructions on re-calibration.
The inclinometer has a digital display with an accuracy greater than 0.5
degrees and is powered by a standard 9 V battery. The inclinometer is
mounted on the mechanical sup por t of the ant enn a, lo cated on the right hand
side of the RF back plate, i n order to accurately indicate the elevat ion of the
antenna beam. The antenna has an offset angle of 18.9 degr ees, which is
pre-programmed into the inclinometer so that the angle indicated is the elevation angle of the antenna boresight.
Only the top button of the inclinometer should be used. The top button has the
following functions:
• First press turns the inclinometer ON
• Pressing the button a gain for less than three sec onds turns on the ligh t;
when the light is on, the inclinometer holds the last measurement
• Pressing the button again for less than three seconds turns off the light
• Pressing and holding the button for more than three seconds turns off the
inclinometer
The inclinometer is c alibrated at the facto ry. The mechanical variation is calibrated out at the factory.
N
OTE The angular offset between the aluminum backplate of the antenna and th e

antenna boresight is 10.3 degrees. Thus, if the antenna is adjusted so that the
aluminum backplat e is perfectly vertical, a no rmal inclinometer will read 90
degrees. In this position, the antenna boresight is 10.3 degrees above the
horizon.
The spirit bulls-eye lev el is mounted on the antenna base in order to accurately indicate how level the support base is. The level is 1.250 inches in
diameter, filled with clear minera l spirits. The mounting ca se is brass with a
black finish. The sensitivity per 0.1 inch is 45 minutes, with a tolerance of

Baseband/IF Unit Functionality
The Baseband/IF unit performs the following functions:
• Transmit power settings
• Output power settings
• Maintenance and indication
• Setting transmission frequency
• MPEG-2 encoding of user supplied video and audio
• DVB-S compliant coding, interleaving, scrambling and modulation
• Upconversion of the modulated signal to L-band
• Reception of DVB-S compliant MPEG-2 TS
• Display of transmitted video
• Antenna pointing calculations
• Spectrum Analyzer
The following section s provide de scription s and spec ifications for each of the
above listed functions.
Transmit and Output Power Settings
The transmit power se ttin gs ar e co n tro lled v i a the TRANSMITTER CONTROL panel
of the Norsat NewsLink GUI. The power can be entered manually, or via
transmit power quick keys whi ch store assigned values for low and nominal
power. The low and nominal power level s of the for the qui ck keys are set i n
the T
RANSMIT POWER panel of the Norsat NewsLink GUI.
Maintenance and Indication
If the desired output power setting is above 25 dBm, for both the 15 W and 25
W SSPA, the output power level will be mai ntained at its current level independent of temperature drift. However, if the desired output power level is
below 25 dBm, the actual output power level may fluctuate with temperature.
The Antenna Alignment scre en of the Nors at News Li nk GU I ind icates the signal strength.
Tr ansmission Frequency Setting
The transmission freq uency s etting is co ntrolled v ia the TRANSMITTER CONTROL
panel of the Norsat NewsLink GUI. The transmission frequency can be
entered manually, or via transmit frequency presets which store frequently
used transmit frequen cies, and are set in the F
