1. GENERAL
1.1 Description
The consolidation of Digital TV boosted the installation of “Direct To Home”
satellite TV systems. The continuous release of new packages or 'bouquets' and
services such as Internet require new simplified installation procedures that are capable
of guaranteeing the quality of the signal received.
Because of the wide range of services offered by current satellites and the
increasing in the amount of signals, we have developed new tests, improving the ones
available in classic satellite detectors and meters.
The SATHUNTER+ is the answer to the need for an installation tool that allow
making the job in a fast way and it includes all necessary measurements to secure the
quality of reception. There is a need to discern among satellites, to adjust the antenna
and to check the quality of the digital signal.
The SATHUNTER+ has been designed to guarantee the maximum number of
installations with the best quality, helping the installer to evaluate the results.
The equipment determines if the quality of the signal is enough for reception. For
that, it is based on the internal BER measurement and the modulation error ratio (MER).
The SATHUNTER+ processes all the information and gives to the installer just
the information he requires, making his work as easy as possible.
The SATHUNTER+ is very easy to use and it guides the user through three
steps, enabling to localize the satellite, guaranteeing its identification and accurately
adjusting the receiver antenna to obtain the best quality of signal.
At the SATHUNTER+, the measurement to determinate the quality of the signal is
the MER, which is directly related to the BER (Bit Error Rate). The instrument displays
‘CBER’ and “MER” on the display in graphic bars and alphanumeric data.
1Trademark of the DVB - Digital Video Broadcasting Project.

3. INSTALLATION
3.1 Power Supply
The SATHUNTER+ is a portable instrument powered by a lithium rechargeable
battery. The instrument comes with a mains adapter in order to connect it to the mains
for operation and battery charging.
3.1.1 Operation using the Mains Adapter
Connect the mains adapter to the SATHUNTER+ using the external power
connector [4] (see Figure 6.-) located on the right side panel. Connect the
adapter to the mains and it will automatically start the battery charging process. The
equipment will emit an acoustic indication. It will also display information about the
battery charging (see “3.1.3 Battery Charging”) on the screen. When the battery is
already charged, the instrument will automatically disconnect. To stop the charging
process, press any of the three keys [1], [2] or [3], for more than 2 s
(the battery-charging screen will disappear).
To start operation, keep any of the three instrument keys ( [1], [2] or
[3]) pressing down for more than 1 s. The instrument will start up. The battery
charging process will stop until the equipment starts up. The charging process will be
slower when the equipment is on.
CAUTION
Before using the mains adapter, make sure that it is the appropriate one for your
mains system: Mains power adapter model AL-101B.
The mains adapter is exclusively designed for indoor use.
3.1.2 Operation Using Batteries
The instrument is powered by a 7.4 V and 2.2 Ah Li-Ion battery.
In order to the equipment works using the battery, you need only press any
instrument key ( [1], [2] or [3]) for more than 1 s. With the battery fully
charged, the SATHUNTER+ has an approximate autonomy of 80 minutes in continuous
operation and at the worst conditions (powering a universal LNB and identifying a
signal).

USER’S MANUAL. SATHUNTER+.
Page 8 10/2010
When the battery is flat, you will hear an acoustic indication and the screen will
show the message “BATTERY LOW“. Afterwards, if the battery is not charging yet, it
will show the message “VERY LOW BATTERY” and it will emit a warning acoustic
indication. If it is not immediately connected to the mains, the instrument will
automatically switch off.
3.1.3 Battery Charging
To fully charge the battery with the SATHUNTER+ switched off, connect the
mains adapter to the external power supply input
[4] (see Figure 6.-). Then
connect the adapter to the mains. The charging process will start automatically. The
instrument will emit an acoustic indication and the display will show the battery voltage
level, the charge percentage and for how long the battery has been charging.
Figure 1.- Battery charging.
When charging is completed, the instrument is automatically disconnected from
the mains and it will emit two acoustic indications. At the same time the display will
show how long the battery has been charging.
The charging time depends on the state of the battery. If the battery is completely
flat, the charging process will take around 100 minutes. When the battery is fully
charged, the instrument will disconnect automatically. The charging process must be
carry out in a range of temperatures between 5 &C and 40 &C.
IMPORTANT NOTE
At starting the battery charging process and using the instrument for a long
period of time, it could be observed a heating of the instrument. This heating is
normal in the power margin that must be dissipated, according to the battery
charge status and the LNB consumption.
IMPORTANT NOTE
If the equipment is operating and the voltage adapter is connected, the charging
process will be longer. It will depend on the consumption.

4.3 Antenna Adjustment for Optimum Reception
The SATHUNTER+ has been designed to adjust the orientation of a satellite
antenna in order to achieve the optimum reception of a digital satellite signal from a
previously memorised one.
The adjustment process consists of three steps:
1 Satellite detection and location: 1> DETECT
2 Identification of a located satellite: 2> IDENTIFY
3 Precise antenna adjustment for optimum signal quality. 3> ADJUST

USER’S MANUAL. SATHUNTER+.

Figure 9.- Valid sequences diagram.
During the whole process the instrument checks the state of the cable, the
connector and the LNB. Therefore, if it detects that the noise level is below a reference
level (standard value: 10 %), it will be shown the message “LNB NOT DETECTED“ at
the bottom of the screen. On the other hand, if the signal power is higher than the
threshold the equipment will emit a variable frequency tone to help the user in order to
position the antenna and detect the maximum signal power.
If the LNB power supply voltage falls 1 V below the nominal value, the instrument
will show the message “LNB SHORTCIRCUIT“ and will temporarily switch off the power
supply to prevent overloads. After one second, the power supply will switch on again,
and it will check if the short circuit has disappeared.
This may occur due to a temporary fall in the voltage when connecting or
disconnecting the instrument from the rest of the installation. The message may also
appear when the power supply is overloaded because of using a LNB with excessive
consumption.
4.3.1 Satellite Detection and Location (1> DETECT)
This function is directly accessed on starting the instrument. If it is not the active
function, press key [1] to select it.
The purpose of this function is to detect when the antenna is pointing at a satellite
(detection).
In order to do this, connect the instrument to the low-noise amplifier that is located
at the focus of the parabolic antenna. On the screen you will see two horizontal bars
that can vary depending on the power signal. The upper horizontal bar keeps the
maximum value measured during tracking. The lower horizontal bar shows the signal
power in real time. In addition to these bars, there is an audible signal that varies
depending on the power signal, from low tone (low power) to high tone (high power).

USER’S MANUAL. SATHUNTER+.
Page 18 10/2010
Figure below shows the display of SATHUNTER+ in detect mode. Among the
data shown, there is the voltage average supplied to the LNB and if it is being applied
the 22 kHz signal.
Figure 10.- DETECT function.
If no signal is detected, the display will show horizontal bars at minimum level and
the percentage of power rate at 0 %. There will not be either audible signal and it will
appear the message “LNB NOT DETECTED”.
4.3.2 Satellite Identification (2 > IDENTIFY)
Once a satellite has been detected (by localising a power maximum), you should
check if the received signal corresponds to anyone of the memorised satellites. Select
the satellites identification function 2> IDENTIFY by pressing key [2].
The identification system is based on a database of satellites previously loaded to
the equipment. Consult the configuration sheet supplied with the instrument for further
information on satellites that the instrument can detect.
The instrument can memorise up to fifty combinations of frequencies and
polarizations (50 test points).Frequency measurements are configurable by software.
They can be shown as a FR (intermediate frequency) or DL (Downlink frequency). The
number of active points (selectable) can be also configured. A greater or lesser number
of satellites can be identified depending on the number of active points and how many
you want to assign to each satellite. Therefore, for example, if we assign one frequency
and the two possible polarizations to each satellite (i.e. 2 points for each satellite) and
they are activated 14 points, the instrument will be able to identify a total amount of 7
satellites. See the configuration sheet delivered with the instrument for further
information. Each test point has a name up to 8 letters assigned to it. It will be shown on
the display when is selected.
