Once the Norsat LinkControl application has its location and desired satellite, it will
automatically calculate the look angles required to point the antenna at the satellite.
T
he application calculates four values:
Compass Azimuth
–
magnetic compass bearing to which the antenna should be set
Elevation
–
angle to which the inclinometer should be set
Polarization
–

Step 7:
Acquire Satellite and Peak Antenna
Acquiring the satellite and peaking the antenna involves the use of the built
-
in spectrum
analyz
er, a DVB lock indicator, and a modem lock indicator.
The process of acquiring a satellite and peaking the antenna is easiest when a satellite
has a DVB carrier and a beacon. Where a DVB carrier does not exist a beacon can still
be used.
Note: When nei
ther a DVB carrier nor a beacon exists, other types of carriers, if
present, and/or reference satellites can still be used to acquire a particular
satellite. This chapter does not address such occurrence. To learn more about
how to handle such situations,
attend a Norsat training session.
The reference level (dBm) and the dB per division functions will be set to auto mode
(these are pre
-
selected and set from the factory).
Note: Advanced users can deselect either or both the reference level and the dB
pe
r division in order to configure the spectrum analyzer to settings of their choice.
Additionally, the Center Frequency and Frequency Span are also adjustable
using scroll arrows.
The process of acquiring a satellite and peaking the antenna requires the us
e of the
Spectrum Analyzer Screen.
Viewing
the Receive (Rx)
Spectrum Analyzer Screen
To open the Receiver Spectrum Analyzer Screen, click the down arrow beside the
Spectrum Analyze

time required
to
draw the trace on the spectrum
analyzer. It is normal to leave
this set t
o high detail as it
may be difficult to distinguish signals
when the detail is
set to
o
low.
Detail changes the resolution bandwidth of the Spectrum
Analyzer. The following resolution bandwidths are available:
600Hz, 1.2KHz, 2.4KHz, 4.9KHz, 9.8KHz, 19.5KHz
and
39.1KHz
