1. Manual
Inside the “manual” menu there are specified the different options for
setting up the input, output and modulation parameters.
1. This field shows the type of parameter that is selected at the moment.
Options: Input Terr, Out Terr, Out TV.
2. This field shows the parameter that is selected. In order to move
around the different options we have to use the “Up” and “Down” buttons
of the keyboard. Click on OK to edit the selected parameter and
Right/Left for changing it. Once it is configured press Cancel.
Terrestrial input (Input Ter)
In this option you will be able to configure the input parameters of the terrestrial
signal:
- Freq. (MHz): Input frequency of the multiplex that you wish to tune. In order to
introduce the frequency, press the “OK” button and the cursor will be placed over
the frequency. With the keys of the cursor, we can move through all the digits and
change the values. Press “OK” in order to save the value. Options: 170-230 / 470-862 MHz.
- BW (Bandwidth): Selection of the input signal Bandwidth: 8 MHz, 7 MHz and 6 MHz.
Terrestrial modulation (Out Terr)
These options allow configuring the DVB-T/DVB-H modulator of the device.
- Modulation: Output modulation format: 4 (QPSK), 16 (16 QAM), 64 (64 QAM).
- Invert (Spectrum inversion): Activate or deactivate the spectrum reverse in the
modulation.
- GI (Guard interval): Allows selecting the guard interval of the modulation: 1/4,
1/8, 1/16 and 1/32.
- BW (Bandwidth): Selection of the Bandwidth of the modulated signal: 8 MHz, 7 MHz and 6 MHz and 5MHz. The 5 MHz
option is only supported by DVB-H standard.
- Tx Mode (FFT Mode): 8K, 4K and 2k. The 4k option is only supported by DVB-H standard.
- FEC: Indicates the relationship between the redundant bits and the transmitted information bits: 1/2, 2/3, 3/4, 5/6 y
7/8. For example, in a FEC = 2/3 relation we will find 2 information bits and 1 redundant bit.
- Mode: Selection of the modulation standard: DVB-T and DVB-H.
Note: The output useful bits rate will depend on the following parameters: Bandwidth, guard interval, FEC
codification and modulation. In the
Attachment I you will find all the information related to the resulting useful bit
rate in each configuration.
Output configuration (Out TV)
In these options you can configure the output parameters of the terrestrial signal.
- RF Channel (MHz): Output frequency of terrestrial modulation. In order to
introduce the frequency, press the “OK” button and the cursor will be placed over
the frequency. With the keys of the cursor, we can move through all the digits and
change the values. Press “OK” in order to save the value. Options: 47-862 MHz.
- RF Level: Regulation of the output level of the modulated signal. Options: 0-15dB.
