SATHUNTERSATHUNTER
If you have bought the SATHUNTER, this presentationwill help you to start using your unit.
If you have not got it yet, we hope it will help youto take a decision!
SATHUNTERSATHUNTER
With the SATHUNTER, aligning a dishto the required satellite becomes
fast and easy
Anyone even with small technical knowledge
can do the job.
SATHUNTERSATHUNTER
Some hightlights
• Small, light, easy to use and rought.
• It works for DVB-S and DVB-S2.
• Identifies the satellite and reads the service listof the selected transponder.
• Measures Power, MER, CBER and LBER for fine adjustment.
• Drives the LNB with voltage and 22 kHz signal.
• Li+ batteries.
SATHUNTERSATHUNTER
Before starting...
• Check if the satellites / transponders preprogrammedin the SATHUNTER are good for your application.
• SATHUNTER needs to be programmed before usewith transponder information from the satellites you wantto work with.
• Each set of transponder data (frequency, FEC...)will become a test point in the SATHUNTER which you can label, so you identify it easily.
SATHUNTERSATHUNTER
Why use preprogrammed satellites?
• Set up to 16 satellites.
• Set for testing the 4 polarities on up to 4 satelites.
• Set only one point to avoid any possibility of error.
This is a solution to make the installation and measurementswith minimum operation complexity.

Replaceable input connector
The input connector is a frequent point of breakdown in fieldinstruments. Therefore the SATHUNTER comes with areplaceable F/F adapter.

Li+ batteries
• Before starting operation make sure batteries are charged and eventually charge them for a few hours using the AL-101B power charger supplied.
• The batteries are Li+, so not only battery life is longerbut also the charging time is quite short.
• The unit comes with a power adaptor and a chargerfor the car lighter.

If the preprogrammed configurationis not good for your application, please go
to the “modifying configuration” section

SATHUNTERSATHUNTER
STEP 1
• Switch on by pressing key #1 for more than a second.• Move the dish towards the position where you’d expect
to find the satellite you wish to align.• As soon as you receive signals from a satellite, the bargraph
will show some activity and the acoustic indicator will beep.
Detecting a satellite
SATHUNTERSATHUNTER
STEP 1
• Move the dish smoothly up, down, left and right to getthe maximum bargraph deviation.
• Display will be also showing additional information:
Detecting a satellite
Actual LNB voltage supplied
Battery charge level
Current signalenergy reading(bargraph and
percentage)
22 kHz signal On/Off
Maxhold of the signalenergy reading(bargraph andpercentage)
SATHUNTERSATHUNTER
STEP 1
There are some of the messages you can get on the display:
Detecting a satellite
• “LNB SHORT CIRCUIT”. Look for a short circuit in the cable to the LNB, connectors, LNB itself...
• “LNB NOT DETECTED”. Check connectors and LNB. Check that the cable run is not too long
SATHUNTERSATHUNTER
STEP 2
• Once you have the maximum bargraph deviation, press key . The label of the first test point will be displayed (for example TP64).
• Right after the label the SATHUNTER will display all information.
Identifying satellite
Test point name
Orbital position + Network name
Service list IF frequency
SATHUNTERSATHUNTER
STEP 2Identifying satellite
Every time you push the key , the next text point will be selectedin a cyclic sequence.
SATHUNTERSATHUNTER
STEP 3
• Once you know you are on the right satellite, press key .
• Another bargraph showing MER measurement (both graphicallyand numerically) will appear together with the CBER and/or LBER measurement (configurable with the software).
Optimising the quality
SATHUNTERSATHUNTER
STEP 3
• Move the LNB to maximise the bargraph deviationand eventually try very small dish fine tuning.

MODIFYING CONFIGURATIONIf you wish to work with satellites different to thosepreprogrammed from origin or wish to change the test points inany way, you should proceed as follows:
• Get information on the satellites and transponders of your choice.
• Edit the configuration file accordingly by using the SATHUNTER software supplied and change the programming of the SATHUNTER using the communications cable included as well.

• Satellite and transponder information is available through different sources.
• Several websites offer reliable data which can be usedto configure the SATHUNTER.

SATHUNTERSATHUNTER
Edit the configuration...
• Install the SATHUNTER software supplied on your PC.
• Connect the included cable to the USB port.
• Start the SATHUNTER.
• Run the software SATHUNTER.
• Select Tools Detect from the menu.
SATHUNTERSATHUNTER
Edit the configuration...
• Select Tools Receive from the menu
• Software should then take a few seconds to extractthe test points which are currently installedon the SATHUNTER.

Edit the configuration
• Select Edit Point from the menu.You should then get the screen where you can modify the test points as you need.
Select the detectionpoint which you wantto edit.
SATHUNTERSATHUNTER
Edit the configuration
Select the LNB voltage
Enter the IF frequencyof the desiredtransponder
Select ON/OFF for the 22 kHz signal
if needed
Enter the symbol ratefor this transponder
Select whether thetransponder is DVB-S2or DVB-S
Select the Code rateor leave it in Auto if
you don’t knowthe value
Enter a name (4 chars)so that you can identifyit when you see it on the SATHUNTER
SATHUNTERSATHUNTER
Edit the configuration
• You should perform the same procedure for everytest point you need to charge.
SATHUNTERSATHUNTER
Edit the configuration
• Select Edit Config from the menu.
• You should then get the screen where you can modify the configuration of all points.
SATHUNTERSATHUNTER
Edit the configuration
• Select the number of test points that you want to be activeon the SATHUNTER.
• If, for instance, you have edited 10 tests points, you should enter “9” as the last detection point.
SATHUNTERSATHUNTER
Edit the configuration
• Once all changes have been made, you should save the file,either with the same name, thus erasing the original,or with a different name thus keeping the originalfor future reference.
• Select File Save from the menu.You should then get a regular Windows screenwhere you can name and save the edited file.
SATHUNTERSATHUNTER
Edit the configuration
• Select Tools Send from the menu.Software should then take a few seconds to installthe new configuration onto the SATHUNTER.
• Note that this will install the last filethat you have been working on and thatyou have already saved.
SATHUNTERSATHUNTER
Edit the configuration
• Select File Exit from the menu.
• Turn OFF the SATHUNTER and disconnect the cablefrom the computer.
