Superior Broadcast ATVCA Amplier
About user interface, the amplier can be set in two modalities, ‘LOCAL’ or
‘REMOTE’. This double option is selectable by ‘Fnc’ → ’Sts’ menu. We suggest
customer to set this switch in ‘REMOTE’. No damage occur to the amplier also if
it operates continuously in ‘LOCAL’ set, but user has faculty to set unintentionally
the amplier to operate in a different mode then planed, especially when navigating
amid menus with a not rm skill. When amplier is a part of a complex system,
for instance a transmitter employing several items combined, the ‘REMOTE’ set
is the strongly recommended, also in order to allow the System Manager Unit to
best interacts with all other partners joined.
Amplier(s) and an exciter (synonymous of Modulator) complete a transmitter
equipment. Both these units work in synergy but operate independently by their
own Hardware/Software endowment. The exciter unit supplies RF modulated signal
to the amplier, the amplier interacts with a feedback signal, often referred as
‘INTERLOCK’. Interlock signal can arrest RF supply from exciter, this occur when
protection circuit or user’s action has imposed a general stop. Interlock action is
not a safety issue about the amplier integrity, but when RF is still supplied during a
stop phase by the exciter, a residual RF signal ows through the amplier’ circuits
till the antenna. In many countries such an occurrence is unlawful.
The amplier is equipped with an autonomous circuitry that manages entirely
every working state and defends all ampliers’ parts by means of protection
routines. No equipment joined with the amplier cans by-pass a protection action.
This restriction is essential when an amplier is included as a ‘slave’ partner in a
combined system. In such a system, a wider interaction among all partners is put
into action by the main equipment and so, some contradictory settings may be
set followed then by incoherent behaviors. Because the high power handled, an
overall incoherent behavior may damage some part of the plant or, as frequently,
the transmitted signal may not comply all recommendations of Communications
Supervisory Authority. In this case, user must follow all technical information related
to the complete system.
