2. Device Status
In the option “Device Status” are specified the main parameters of the module
at this moment.
- Front End: It indicates whether the module is hooked or without
signal.
- Input bit rate: Transfers of data in the terrestrial tuner input.
- Output bit rate: Transfer of data in the module output.
- BER before and after Viterbi: It indicates the error rate of bits of the
input signal before and after the correction produced by Viterbi
algorithm.
- MER: Parameter that indicates the quality of the input modulated
digital signal, expressed in dB.
- Noise Margin: It indicates the difference between the value of current C/N and the value of C/N at the point of
pixilation of the signal, that is, the quantity of dBs of C/N measure that are needed to lose the input signal.
-Temperature: It indicates the current temperature of the module in degrees.
3. Set Front End
In this option you will be able to configure the input parameters of the terrestrial
signal:
- Channel: Input channel of the multiplex that you wish to tune. When
you select the output channel, the field “Frequency (MHz)” will be
modified automatically, adapting itself to the selected channel.
Options: C5-C12/C21-C69.
- Frequency (MHz): Input frequency of the multiplex that you wish to
tune. When you modify this field, the field “Channel” will be also
modified, indicating the channel equivalent to the selected frequency in
the case that this frequency corresponds to the frequency of a channel.
Options: 170-230 / 470-862 MHz.
- Bandwidth: Selection of the input signal Bandwidth: 8MHz, 7MHz and 6MHz.
4. Modulator Set Up
This option allows configuring the DVB-T/DVB-H modulator of the device.
- Bandwidth: Selection of the Bandwidth of the modulated signal:
8MHz, 7MHz, 6MHz and 5MHz. The 5MHz option is only supported by
DVB-H standard.
- FFT Mode: Selection of the number of carriers used in the
modulation. Options: 8K, 4K and 2k. The 4k option is only supported by
DVB-H standard.
-Spectrum inversion: Activate or deactivate the spectrum reverse in the
modulation.
Allows selecting the guard interval of the modulation: 1/4, 1/8, 1/16
and 1/32.
- 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.
- Modulation: Output modulation format: 4 (4 QAM), 16 (16 QAM), 64 (64 QAM).
- Advanced settings:
- 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.
