SATHUNTER Satellite pointing made easy DVB-S2 DVB-S
If you have bought the SATHUNTER, this presentation • will help you to start using your unit. • If you have not got it yet, we hope it will help you • to take a decision!
With the SATHUNTER, aligning a dish to the required satellite becomes fast and easy Anyone even with small technical knowledgecan do the job.
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.
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.
Why use preprogrammed satellites? This is a solution to make the installation and measurements with minimum operation complexity. You can... • 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.
Replaceable input connector The input connector is a frequent point of breakdown in field instruments. Therefore the SATHUNTER comes with a replaceable 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 goto the “modifying configuration” section Click me to go there directly.
STEP 1 Detecting a satellite • Switch on by pressing key #1 for more than a second. • Move the dish towards the position where you’d expectto 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.
STEP 1 Detecting a satellite • Move the dish smoothly up, down, left and right to getthe maximum bargraph deviation. • Display will be also showing additional information: Actual LNB voltage supplied 22 kHz signal On/Off Battery charge level Maxhold of the signal energy reading (bargraph and percentage) Current signal energy reading (bargraph and percentage)
STEP 1 Detecting a satellite There are some of the messages you can get on the display: • “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
STEP 2 Identifying satellite • 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. Test point name Orbital position + Network name IF frequency Service list
STEP 2 Identifying satellite Every time you push the key , the next text point will be selected in a cyclic sequence.
STEP 3 Optimising the quality • 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 LBERmeasurement (configurable with the software).
STEP 3 Optimising the quality • Move the LNB to maximise the bargraph deviationand eventually try very small dish fine tuning. MAXIMUM DEVIATION OPTIMUM CROSS - POLARIZATION
MODIFYING CONFIGURATION • If you wish to work with satellites different to those • preprogrammed from origin or wish to change the test points in • any 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.
Get information... • Satellite and transponder information is available through different sources. • Several websites offer reliable data which can be usedto configure the SATHUNTER. www.lyngsat.com www.satcodx.com
Get information... Enter Lyngsat web site and click on your region in Packages.
Get information... Click on the desired satellite:
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.
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 detection point which you want to edit.
Edit the configuration Enter the IF frequency of the desired transponder Select the LNB voltage Select whether the transponder is DVB-S2 or DVB-S Select ON/OFF for the 22 kHz signal if needed Enter the symbol rate for this transponder Enter a name (4 chars) so that you can identify it when you see it on the SATHUNTER Select the Code rate or leave it in Auto if you don’t know the value
Edit the configuration • You should perform the same procedure for everytest point you need to charge.
Edit the configuration • Select Edit Config from the menu. • You should then get the screen where you can modify the configuration of all points.
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.
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.
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.
Edit the configuration • Select File Exit from the menu. • Turn OFF the SATHUNTER and disconnect the cablefrom the computer. • You are ready to work with a newly configured SATHUNTER.
