For DVB-T/T2 it can be said that, hopefully but not always, the digital readout; BER
(bit error rate) and C/N (Carrier/Noise) will correspond well with the analog setting of
the antenna.
Quite often the antenna needs to be re-directed a little bit in order to maximize the
digital-values (which are of more importance then the analog readout).
The PRE-BER value (before correction in the demodulator) is the most useful signal
for aligning the antenna. The POST-BER value (after demodulator corrections)
increases in correspondence with the increasing of the PRE-BER value.
In DVB-C mode the meter will show:
- C/N (Carrier/Noice) This value should be as high as possible.
- Pre BER is before correction by the demodulator and
- RS Error: Reed-Solomon bad blocks (like the UCB: Un Corrected Blocks) should be
as low as possible (should be zero).
Pressing the Mode button again will take the meter to the
Multichannel-mode
where
the analog (dB) signal strength of up to 30 channels can be easily readout.
The display shows six channels on each page and there are five pages. Step through
the pages with the “UP” and “DOWN” buttons.
