At the place where the setting is made, there must be a TV set, a special satellite tuner with a very wide scale of the signal quality level, with the indication of the percentage division of the entire scale.
To tune the antenna to a group of satellites called HotBird 13E in the receiver itself, you must set the parameters of a very strong transponder, for example, you can choose 11034 V 27500 - 3/4, 11034 there will be a frequency in megahertz, V means vertical polarization, 27500 stands for symbol rate, 3/4 is the error correction code.
This can be done if you enter the menu called “Setup / Single search”, where you should select the name of the required satellite, that is, Hotbird 1/2/3/4/6, in the available field called “Satellite”, to implement the hint below the menu can display the remote control buttons remote control, with the help of which the selection is made.
Then you should go to setting the converter itself in the submenu called “LNB Setting”, where you need to indicate in paragraph "Type LNB" - type "Universal", "22K"- will not turn on when making a selection universal converter, “DiSEqC1.0” must be "Disable", "DiSEqC1.1" must be “Disable”, “Positioner” must be “Off”, “Polar.” should be “Auto”, “Tone” should be “On”, then you need to press the button called “Menu” and confirm the selection with the “OK” button. Then you should select the transponder number in the field called “TP number”, it will be “17/109”, which corresponds to a frequency of 11034 megahertz, the type of scanning of the “Open” TV channels should be indicated “No”, which will enable you to scan all TV channels, “ Channel Search ”should be“ TV + Radio ”,“ Search Mode ”should be“ Scan by Preset ”.

After finishing the installation of these settings, you need to go to the search for the satellite itself. First you need to use a compass to direct your antenna along an azimuth of two hundred and eight degrees, and using the marked divisions on the antenna mount itself, set the required tilt angle, which is twenty-three degrees. If your antenna does not have a tilt angle scale, then it will be possible to set it using a protractor or protractor. Then, tracking the available scale level called “Quality” on the TV itself, you need to slowly turn the antenna itself to the left or right, literally only one degree, until a green bar appears. If, when turning the antenna to the left or to the right, you cannot achieve the appearance of a green strip, and the azimuth itself is indicated correctly, then you need to shift the antenna itself up or down one degree, and then repeat the entire search. After the appearance of the strip, it follows with a smooth turn satellite dish to the left or to the right, achieve the maximum level of the scale called “Quality” from the one that will be displayed in front of you as a percentage. Then carefully you need to fix the antenna mount itself, which allowed you to move it to the left or to the right, and following the existing level of the scale called “Quality”, you need to move the antenna up or down until reaching maximum value, which, in the end, should also be fixed. After making these settings, a significant increase in the level of the television signal will also be helped by turning the converter around the axis of the holder itself until the maximum value is reached, which must also be fixed.
When the satellite dish is tuned to the most maximum level TV signal from HotBird satellites, you should scan television channels... To do this, in this same menu, you need to go to the line called "Search" and press the button on the remote control called "OK", as a result of this, all information about the scanning process will be displayed. After scanning, you should save the results. If, as a result of viewing, there are TV channels with a scattering image "into squares", then you should adjust the satellite antenna according to the parameters of these channels (that is, the weak transponder), which is done in the same way as searching for a satellite using the strongest transponder, only using the parameters of the weak transponder, which can be seen by pressing the "Info" button.
To connect a receiving antenna system, as a rule, there is one input (F-connector). Most of digital receivers there is an RF loop output (LOOP) for connecting an additional receiver (for example, analog) to the same antenna system. True, the need to connect an analog satellite receiver is very rare, since almost all channels that still continue analog satellite broadcasting, are broadcast in digital format... True, some models of terminals do not have a loop output, but this, according to by and large is not a disadvantage. There are receivers with two inputs for connecting LNB. As a rule, these are terminals with a recorder for HDD... The presence of two independent receiving paths allows you to connect two different independent antenna systems.
It is much more difficult to assess the sensitivity of the high-frequency tuner of a digital satellite receiver than an analog one. The fact is that due to the fact that when transmitting a digital signal, anti-jamming coding methods are used, television signal from the output of a digital receiver, either reproduced in absolute quality without any visible distortion, or absent at all. An intermediate state, when the reception is accompanied by distortions ("scattering" of the picture or "dropping out" of individual frames), can differ from the state of normal signal reception by a change in the signal-to-noise ratio at the receiver input of 0.5-0.7 dB. Objectively assess the sensitivity different models receivers fail without special measurements. Most often, the problems that arise when receiving individual channels or packages with a digital satellite receiver are not caused by the sensitivity of the tuner, but by deviations from the broadcasting standard of some broadcasts or problems with the receiver software.
Indeed, there are models of digital receivers, the sensitivity of the high-frequency path of which is noticeably lower than that of other devices. As a rule, these terminals are classified as ultra-compact. In such models, a simplified tuner is used, which is not placed in the form of a module installed on the main (mother) board of the receiver, but is part of the circuit located on the board itself. Although the tuner is simplified, it has more complex scheme than a hewlett packard printer for example.
For broadcasting DVB-S2 / HDTV packets, 8PSK modulation is usually used transmitted signal providing more high speed data transmission. To receive such broadcasts, it is required to provide better signal noise immunity. Notable models HDTV receivers are equipped with a universal receiving path that supports reception of signals with QPSK and 8P5K modulation.
Hybrid receiver models (satellite / cable or satellite / terrestrial) contain two separate receiving paths, equipped with separate inputs and outputs.
The software of the digital satellite receiver supports the installation of the basic parameters used in receiving system LNB:
1) LNB type... As a rule, the most common LNB list consists of two types: universal and single. Sometimes there are other options: universal (differing in the values of the local oscillator frequencies), dual (with a built-in switch), SMATV (without a local oscillator - operating the receiver in a broadband cable network broadcast).
2) LO frequency... The user can select from the list the suggested value of the local oscillator frequency (standard range for converters of Ki and C bands) or enter this value manually. Rarely, but there are receivers with unfinished software, which does not allow the use of C-band converters.
3) LNB control mode. Standard functions, essential for normal work: Controls the 22 kHz tone used to switch the heterodyne of universal LNBs, switch the polarization of the received satellite signal voltage levels power supply LNB(13/18 V). Some terminals use a simplified power supply that generates an unregulated supply voltage to the LNB. The use of such a receiver in conjunction with LNB modifications intended for use in collective reception systems (Twin, Quattro), or in networks built using multiswitches, will not allow individual network users to correctly control the choice of signal polarization. Some models are equipped with a power-on function increased voltage LNB power supply, which can be effective with a significant length of cable connecting the receiving antenna system and a receiver. Sometimes it turns out useful function forced shutdown power supply LNB, available in some receiver models. Satellite Receivers with an additional digital receiving path terrestrial television equipped with the ability to supply power to the preamplifier of the terrestrial antenna.
If the antenna is already tuned to desired satellite, and the manufacturer entered the channel parameters into the receiver's memory, then the user will not need additional efforts associated with channel search. Most often, the receivers offered on the market do not contain internal memory formed channel lists. It is also possible that the user may need to tune the antenna. If the receiver can cope with both tasks, then it has the necessary minimum functional.
The accuracy of the antenna tuning and the possibility of receiving channels from the selected satellite are indicated by indicators designed graphic objects OSD. They can be presented in the form of bars with a variable length corresponding to the value of the displayed parameter, or in the form of a conventional digital indicator. Most often, the menu contains indicators for displaying two settings: "Signal strength" and "Signal quality". The first indicator shows the power level of the high-frequency signal supplied from the antenna system to the receiver's input. The headroom of this parameter allows you to increase the length of the cable connecting the antenna to the receiver. The very presence of this signal informs about the presence of the receiver connection to the antenna and the LNB serviceability. Usually, it is not the absolute value of the RF power that is displayed, but the proportional value, expressed in relative units(more often in percentage terms). The signal quality indicator reading is related to the signal-to-noise ratio at the receiver input or to the relative error rate in the received digital signal... It is according to the indications of this indicator that they judge the accuracy of tuning the antenna and receiver to the selected digital package... The Signal Quality value is given either in relative units (percent) or in signal-to-noise units (dB). Sometimes the functions of both indicators are performed by one meter. Some receiver models display the signal level value only when the antenna is tuned to the selected package. This is not always convenient. Especially when the receiver is used as a "tuning kit".
Tricolor TV offers to watch many channels via satellite, in excellent quality... And to find out which frequencies correspond to which channels, you need to use special tables.
This is a high-quality satellite communication that works over a vast territory (including Siberia), and includes many interesting channels, even such as TNV, which is quite rare in packages. However, to be able to enjoy all the benefits of this offer, you need to be able to properly configure it.
Setting up broadcasting (all channels, including TVN, and throughout the entire territory, including Siberia) is possible if you have:
- Receiver for receiving TV channels (including TNV).
- Antenna of the required diameter (namely, 90 cm).
- Two converters - linear and circular polarization.
- Multifeed.
The broadcasting package from Tricolor TV is becoming very popular, and everyone can connect it. This can be done even without the help of specialists. It is enough just to know what settings need to be set. Of course, the list of channels (Siberia) is not perfect (although it includes TNV). There may not be many channels you need, but this is not a problem, since you can watch them on other satellites.
Customization features
Before learning about the frequencies of Tricolor TV, you need to correctly connect and configure all the equipment. You need to start from the location of the antenna. To receive all channels, including TNV. Later, you will need to get acquainted with large quantity settings, including lnb and others. When placing the antenna, make sure that it faces south, and that there are no high obstacles there. Ideally, there should be a clear horizon in front of the antenna. Then the customization will pay off.
It's great if you can adjust the position of the cymbal during operation to get a cleaner signal. This setup is not only flexible, but also justified by operational needs.
The instructions will indicate how to assemble the antenna, after which you will need to move on to the next step - setting up the broadcast and the channel table.
You will come across lnb when setting up a multifeed. For everything to work perfectly, the lnb value must be "single". If lnb is assigned a different value, adjustment to Tricolor is not possible.
Many settings are made manually and cannot be adjusted automatically. So, you will need to independently configure your entire system to receive a specific satellite, and it all starts with system setting... Here the value of the Number should be 1. It is important to observe the value of the lower line 10750, the upper line 10750. They may be different by default. However, you need to bring these frequencies to such a single form. Change the values manually if necessary.
Next, configure manual settings. Select antenna number and frequency as instructed in the instructions. V in this case 1, Eutelsat W4, 12226. Select the flow rate 27500. This is the optimal value with which it is convenient to work. After these simple manipulations, you need to look for a signal and navigate by the light indicators. There are no particular difficulties at this stage, but make sure that the mirror has full overview and you didn't block it.
Once you have acquired the satellite signal, it will be very easy to tune the channels.
What channels are there?
To connect the channels themselves, just select the channel search in the menu. The receiver itself will find all the channels that are provided by this direction communication. Of course, you can also do everything manually if you enter the details of each channel yourself. This way you can achieve excellent signal quality. Below is a table of frequencies.
This table lists all the channels that might interest you.
When faced with setting up receivers and DVB-cards for the first time, even experienced computer specialists sometimes give up. No, they cope with the installation of drivers, and with the struggle with the spacing of interrupts, etc. The difficulty is caused by the settings for a specific transponder. Questions like: What are the frequencies 9750, 10600, I entered everything correctly, why are 50 channels scanned for a friend, but I only have 20? There is nothing complicated here, just the settings of satellite receivers have some peculiarities.
As you know, for radio systems satellite communications in the downstream direction (satellite - ground), the frequency range from 10700 to 12750 MHz is allocated, called the Ku-band. The width of the range, respectively, Fcu = 12750 - 10700 = 2050 MHz. Electromagnetic vibrations such frequencies experience strong attenuation in cable lines, therefore, in the receiving device (converter), not only amplification of vibrations occurs, but also a range conversion (frequency lowering). For this, a process called heterodyning is used. Its essence is as follows: when multiplying the received frequency and the frequency of the reference oscillator, called the local oscillator, many new spectral components (harmonics) arise, of which we are interested in two components, the difference and the total: Fget * Fc = F (get-c) + F ( het + c) (first order harmonics). The total harmonic F (het + s) is suppressed by filters. Difference frequency F (get-s), called intermediate frequency (IF), is allocated by a band-pass filter, amplified and fed into the cable.
Note that in the case of receiving the C-band, the frequencies of which lie in the range of 3400 - 4200 MHz, the local oscillator frequency is higher than the received one and is usually equal to 5150 MHz. In this case, the expression takes the form Fget * Fc = F (c - het) + F (c - het). The essence of this does not change - the total frequency is choked by filters, and the difference frequency is amplified and fed to the receiver.
For the converted satellite signal, a range from 950 to 2150 MHz is allocated, called the L-band. The width of this range, respectively, FL = 2150 - 950 = 1200 MHz. As you can see, this band is two times narrower than the Ku-band (2050 MHz). Note that the entire C-band fits into the allotted band.
Let's go back to the Ku-band. To get around this limitation, the Ku-band was split into two sub-bands - upper and lower. The lower one is from 10700 to 11700 MHz, the upper one is from 11700 to 12750 MHz. Accordingly, for each band, the converter uses its own local oscillator, with frequencies of 9750 MHz for the lower and 10600 MHz for the upper sub-bands. In this case, the IF values lie from 950 to 1950 MHz (950 = 10700 - 9750 and 1950 = 11700 - 9750) for the lower, and from 1100 to 2150 MHz (1100 = 11700 - 10600 and 2150 = 12750 - 10600) for the upper subranges. Accordingly, the bandwidth is 1000 MHz for the lower and 1050 MHz for the upper sub-bands. As you can see, these bands are narrower than the L-band (1200 MHz). Indeed, the upper bound of the lower sub-range is 9750 + 2150 = 11900, and the lower bound of the upper sub-range is 10600 + 950 = 11550.
Thus, in the frequency band from 11550 to 11900 MHz, the upper and lower sub-bands are superimposed and signal reception is possible in both of them. This explains the fact that the crossover frequency (Switch), which is usually equal to 11700 MHz, is chosen conditionally and can be changed based on the quality of signal reception lying in the overlap region. Indeed, the stability of the heterodyne corresponding to this frequency range, possibly narrow-band interference in the IF cable, may require a forced change in the crossover frequency in order to activate another local oscillator and, accordingly, obtain a different IF.
Technically, switching the local oscillators in the converter is very simple. The tuner of the DVB receiver, together with the supply voltage (13 V or 18 V), can also feed the converter a signal with a frequency of 22 KHz and an amplitude of about 1 V. The presence of such a signal informs the converter about the need to switch to the upper sub-band of 11700 - 12750 MHz.
Why do you need frequency conversion?
Any radio signal receiver, in addition to sensitivity, also characterizes the most important parameter selectivity. It shows how the receiver is able to distinguish the desired signal and to reduce the effect of interference. We are talking about frequency selectivity, which characterizes the ability to distinguish signals that are closely spaced in frequency. Historically, given node formed on bandpass filters. It would seem easier to place a bandpass filter at the input of the device. However, firstly in the field high frequencies it is impossible to form a bandpass filter of the required bandwidth and (most importantly) with the required slope of the characteristics in the absorption region (ideally, a "P" -shaped filter), secondly, it is even more difficult to create a tunable filter with an invariable transmission characteristic (we also need tune the frequency).
That is why frequency conversion is used in receivers. Assuming that the difference frequency (IF) is unchanged (it is to this frequency that the bandpass frequency is tuned selective filter), changing the frequency of the local oscillator, we rebuild the receiver. Those. the equality Fгet - Fc = Fпч is always observed. Thus, the tuner of the DVB-receiver contains one more (but not the last) generator, which (and precisely it) must also be tuned to receive the desired frequency.
From
Tuner setting
To scan channels in the receiver, you need to perform initial setup tuner - select the satellites that you receive and specify the necessary settings in their parameters.
Let's consider tuning the tuner using the example of two satellites Eutelsat 36B / Express AMU1 36.0 ° E and Hotbird 13.0 ° E. In the example of DiSEqC settings, the switch will not be used, i.e. the receiver must be connected with a cable to a converter installed on a dish tuned to the corresponding satellite. For tuner settings, open Menu-> Settings-> Search for services-> Tuner settings-> select the model of the installed tuner by pressing the "OK" button.
In our case, Tuner A: Alps BSBE2 (DVB-S2) is installed.
After clicking the "OK" button, we get to the tuner settings menu "Reception Settings", in which we indicate the necessary settings.
For the Hotbird 13.0 ° E satellite, the settings will be as follows:
"Configuration Mode" / "Configuration mode": select - "advanced" / "advanced" (selected using the remote buttons "left" / "right")
"Satellite": - "Eutelsat Hotbird 13B / 13C / 13E (13.0E)"
"LNB": select the converter number - in my case it is "LNB2"
"LOF": choose a use case universal converter- "universal LNB" / "universal LNB", such converters are used to receive a signal in linear polarization
"Increase voltage": in the case of using a short length of coaxial cable, select - "no", otherwise specify - "yes", which allows you to compensate for the voltage drop across coaxial cable long length
For satellite Eutelsat 36B / Express AMU1 36.0 ° E settings will be as follows:
"Satellite" / "Satellite": - "Eutelsat 36B / Express AMU1 36.0 ° E"
"LNB": select the converter number - in my case it is "LNB4"
"Priority" / "Priority": leave "auto" / "Automatic"
"LOF": choose an option manual installation parameters- "User-defined"
Note the three parameters below, they are used for this satellite, the converter must be set to Circular.
LOF / L: - 10750
LOF / H: - 10750
"Heterodyne": - 10750
"Voltage Mode": leave the value - "Polarization"
"Increase voltage": "no"
"Tone mode" / "Tone mode": leave the value - "Band" / "Range"
"DiSEqC mode" / "DiSEqC mode": select the option without using DiSEqC - "no" / "none"
We save the settings that we have set.
Scanning channels.
Let's consider an example of how to manually scan the channels of the NTV + package, which comes from the Eutelsat 36E satellite. The package description indicates the transponders from which the package channels work. Take the 11785 R 27500 FEC 3/4 DVB-S2 / 8PSK transponder as an example. To scan it, go to Menu-> Settings-> Search for services-> Manual search
Set scanning parameters:
"Scan type": - "User defined transponder"
"System": - "DVB-S2"
"Sputnik": - "Eutelsat 36B / Express AMU1 36.0 ° E"
"Frequency": - "11785"
"Inversion": - "Auto"
"Flow rate": - "27500"
"Polarization": - "Circular Right" (R- Circular Right, L- Circular Left)
"FEC": - "3/4"
"Modulation": - "8PSK"
"Roll-off factor": - "0.35"
"Pilot": - "Auto"
"Scanning the network": - "no"
"Clean up before scan": - "no"
"Free only": - "no"
Then press the "OK" button on the remote control or the green button to activate the transponder scan. The same actions will need to be performed with all transponders specified in the package description.
Continuation....
From
I'll make a reservation right away that the settings are the same on different receivers on the E2 and the description is suitable for them as well. To connect the receiver to computer network you need to connect it with a direct LAN network cable to the router or DSL modem configured in router mode. There are two options for the settings, this is the receipt of settings by the receiver via DHCP and manual setting... In the first option, the router or DSL modem must be enabled DHCP server(usually it is enabled by default), which will automatically "distribute" devices to home network required parameters local network.
Receiving settings by the receiver via DHCP.
As mentioned above, this option requires a DHCP server, which can be a router or DSL modem (in most of these devices this feature is implemented), configured in router mode. After connecting the LAN receiver with a cable to the router, open Menu-> Settings-> System-> Network and network connections->
Use interface: - Yes
Use DHCP: - Yes
After selecting these settings, press the OK button on the remote control, answer "yes" to the question "Are you sure you want to activate this network configuration?" and wait for the activation of the network configuration. If the addresses of domain name servers - DNS are not registered in the router or DSL modem, then you will need to specify those used by your Internet provider in the Dreambox, they are set in Settings-> System-> Network and network connections-> DNS settings. The receiver allows you to enter up to two DNS addresses servers. Can be used alternative DNS servers, for example the same Google: 8.8.8.8 and 8.8.4.4
Setting network parameters manually.
If you do not use a DHCP server on your router, DSL-modem, or they do not work correctly, then you need to select a free IP address from your local network, which will be assigned to the Dreambox and register the necessary parameters in the receiver's network settings. To do this, open Menu-> Settings-> System-> Network and network connections-> Configure adapter. Activate the following parameters with the arrows to the right / left:
Use interface: - Yes
Use DHCP: - No
IP address: - here we indicate a free address in your local network (it should not be used in other devices on your local network), in my case I indicated 192.168.88.3
Subnet mask: - specify the subnet mask, in most cases - 255.255.255.0 is used, but there may be another.
Use Gateway: - Yes
Gateway: - here you need to specify the IP address of your router / DSL modem
To be sure if you have specified the correct mask and gateway, you can look at them in the settings network card computer, if it is connected to the same router as the Dreambox, or open the command line of the computer and issue the ipconfig command, where after this command you can see this data in the adapter parameters.
In the same menu, by the blue button, you can go through and change DNS settings servers
Click the OK button to save the DNS settings and adapter settings. After that, you can do a network test and make sure that we did everything right. To do this, open Menu-> Settings-> System-> Network and network connections-> Network test, press the green button on the remote control, after which the receiver will display parameter tests, if everything is done correctly, you will see a similar picture:
Use the red button to exit this menu. Now you can test the availability of the receiver on the local network and the access of the receiver in global network.
Checking the availability of the receiver in the local network and access of the receiver to the global network.
To produce simple check the availability of your receiver on the network, you must ping the receiver from your computer. To do this, on a computer with operating system Windows press the Start button, in the "Run" line, type cmd.exe, click on cmd.exe and enter in the window that opens ping command 192.168.88.3, where instead of 192.168.88.3 we indicate the IP address of the Dreambox receiver, which was allocated by the DHCP server or you entered it manually. After that, press the Enter / Enter button and observe the exchange of packets between the receiver and the computer.
In case you get an error - "The waiting interval for request has been exceeded" instead of exchanging packets, you will need to check the connection network cable to the receiver, the operation of the DSL modem or router, the correctness of entering the IP address of the receiver, and also to double-check network settings receiver, if you entered them manually and did not receive them through the DHCP server.
To check the receiver's access to the global Internet network, you need to connect to the receiver using the telnet protocol. In Windows XP, the built-in telnet client is activated by default, but in Windows Vista and Windows7 needs to be activated.
Using Windows7 as an example, let's look at a couple of ways to do this:
Turning on telnet method 1:
Start - Control Panel - Programs and Features - Enable or Disable windows components- Telnet client (check the box)
Turning on telnet method 2:
Run the command line as administrator (Start - type cmd - in the window that appears, right-click on the cmd.exe application -
run as Administrator):
And we give the command: dism / online / Enable-Feature / FeatureName: TelnetClient
We are waiting for the activation process to complete
For a connection with a telnet receiver, open a window command line and give the command: telnet ip address of your receiver, in my case it is telnet 192.168.88.3 and click Enter
When prompted for a password, specify root and press Enter
When prompted for a password, type dreambox (Carefully! The password will not be displayed) and press Enter
After connecting to the receiver using the telnet protocol, you can check the ping, for example, to yandex.ru and make sure that the receiver has access to the global Internet, for this we give the command ping yandex.ru
If you see the exchange of packages between the receiver and the yandex.ru server, then the network settings on the receiver can be considered complete and you can proceed to further setting up the receiver.
