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 ( ), it analyses for each modulation type
the associated parameters such as the modulation system:
rate, code rate
, etc.,. and determines the value of the signals under test.
