DVB-T2 parameters

As soon as the receiver has completed the synchronization process, several parameters are shown
on the display. When LOCK appears, it means that the digital receiver is receiving a valid data
stream.
In contrast, UNLK means that either the quality of the signal that is present is insufficient, or that
the parameters of the receiver do not match, or that no DVB-T2 signal can be received at this
frequency.
Figure 7-17 DVB-T2 parameters
Once the receiver is synchronized, additional parameters are shown on the display. The DVB-T2
receiver determines these automatically.
In Figure 7-17, the equipment receives a DVB-T2-signal with following parameters:
• 32kFFTe: 32k FFT, the e means "Extended Carrier Mode", i.e. bandwidth utilization is higher
in this mode as additional OFDM single carriers are used.
• Modulation scheme: 64QAM
• Guard Interval (GI): 1/16
• FEC: 3/4
