If the channel is analogue, it determines the television standard of the signal
detected.
When the signal is digital, it analyses the modulation type:
QAM
/
QPSK
/
8PSK
/
COFDM
and all the associated parameters such as the
carriers 2k-8k
,
the
symbol rate
, the
code rate
, etc and it tries to lock to the signal.
In the spectrum analyser and measurements mode, it appears on screen the
name of the
network
and the
orbital position
(only in satellite band).
Activates the band
exploration
function (long pulsation):
The meter explores the entire frequency band to identify the analogue and
digital channels present.
