Automatic signal identification function (AUTO ID)

The TV EXPLORER
according to the established configuration, which are presents in the channel or tuned
frequency. In order to activate this function must once press
useful, is to combine this process with the spectrum monitoring
locating the marker on the levels susceptible to contain a transmission, and activating
later the process of automatic identification in order to identify the present signal.

First it recognises whether the signal is an analogue channel or a digital one. If the
channel is analogue, it determines the television standard of the signal. When the signal
is digital (DVB), it analyses for each modulation type QAM / QPSK / 8PSK / COFDM all
the associated parameters such as the modulation system: carriers 2k/4k/8k, symbol
rate, code rate, etc.,. and determines the value of the signals under test.
If the AUTO ID function is launched in the spectrum analyser mode, the name of
the network will appear temporarily on screen (it also appears in the measurement
display). In case of working in the satellite band the orbital position appears as well.
While performing automatic identification may be the equipment keeps detecting
the NETWORK ID for a long time. During this process, the CANCEL button switches to
SKIP, which allows bypassing the NETWORK ID without losing the other parameters of
the auto-detection.
Whenever the process detects new parameters for a channel or frequency will
create a new channel plan containing the detected information.
