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 / 8-VSB all the associated parameters such as 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.
[30] RF RF signal input
Maximum level 130 dBµV. Universal connector for F/F or F/BNC adapter, with
input impedance of 75 Ω.
ATTENTION
Use the 10 dB attenuator (AT-010) to protect the RF
the input signal level is greater than 130 dB
intermodulation problems.
This accessory allows DC voltages to pass when powering external units as
LNB and amplifiers.
