- Modulation: Output modulation format: 4 (QPSK), 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 depends 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.
5. Set Output channel
In this option you can configure the different parameters of the cable signal.
- Channel standard: It allows you to select the channelling of the cable signal
standards. Options: BG, BG, PAL BG IT, 11, M NTSC, PAL M, PAL N, PAL DK ,
PAL I, BB_AU, DK PAL, L PAL.
- Channel: Output channel of the cable modulation. When you select the output
channel, the field “Frequency (MHz)” will be modified automatically, adapting
itself to the selected channel. Options: C2-C69.
- Frequency (MHz): Output frequency of cable modulation. 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: 47-862 MHz.
- Level: Regulation of the output level of the modulated signal. Options: 0-15dB.
- Calibration: Allows the realization of two tests in order to verify the correct
running of the device.
- Deactivate output: It allows activating or deactivating the ouput of
transmodulator.
- Switch output to CW: It allows activating or deactivating the DVB-T /
DVB-H modulation, allowing visualizing the carrier without modulation
in the selected frequency.
6. System
This option provides information of the transmodulator.
- System logfile: In this field are indicated the registered events in the module.
- Read log: It allows reading the registered events in the module.
- Clear log: It allows deleting all events stored until this moment.
- Export log to USB: It allows you to export all events registered to the
connected USB device.
- NM low Limit (dB): An event of error will be recorded when the value
of Noise Margin is lower than the set value.
- NM hight limit (dB): Once the event of error is recorded (Noise
Margin < Limit Lower NM), this will be Noise Margin value that will
have to be exceed so the module stops being in error.
- Clear log all devices. It allows deleting the events report of all the
interconnected modules.
- Factory default: This option restores the values by default of the
transmodulator.
- System information: It allows you to visualize the basic information of the
module: model, no of series, firmware version, etc.
