When the OUTPUT is enabled, the equipment puts at the output the voltage
selected by the user. When the OUTPUT is disabled it does not apply the voltage at the
output but it works like it was.
In the External power supply mode is the unit powering the amplifiers before the
antenna (terrestrial television) or the satellite TV receiver (house-hold or community)
also powers the external units.
The DRAIN [3] indicator lights when current is flowing to the external unit. If any
kind of problem occurs (e.g., a short circuit), an error message appears on the monitor
('SUPPLY SHORT'), the acoustic indicator will be heard and the instrument will cease to
supply power. The TV EXPLORER
until the problem has been solved, during this time it verifies every three seconds the
persistence of the problem warning with an acoustic signal.

the established configuration, which are presents in the channel or tuned frequency. In
order to activate this function must once press
combine this process with the spectrum monitoring
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.
