3.3.3.2.2.5.- DVB-S2
This functionality enables the obtaining of quality measurements of a
DVB-S2
signal. The
information window is identical to that of the measures
DVB-S
,
DVB-C
and
DVB-T
. The
following sub-menu appears on selecting this function:
- DVB-S2 Measures -
The measure used for evaluating signal quality is
Link Margin (dB)
, that indicates how “far
away” the signal is from the degradation point. Therefore, the greater the Link Margin, the
better the signal. As well as this measure, three others are given:
CBER
,
MER
and
BCHBER
(BCH error correction algorithm bit error rate).
The available measures for a
DVB-S2
are:
Power, C/N, Link Margin, BER, BCHBER and MER
.
3.3.3.2.2.5.1.- Parameters
The only parameter necessary to define for
DVB-S2
signal measurement is
symbol velocity
.
The parameter of speed symbol can be in AUTO mode (in this case the meter will automatically
identify the symbol rate; once found it can be displayed in the window of parameters), or may
it can be selected from the dropdown velocities of most likely symbol. You can also enter the
symbol rate directly using the keypad. The meter has defined the most common: 27500, 24500,
22000, 15000, but you can also enter any other value by using the numeric keypad.
