Theory of Operation
This means, for example, that when a pulse width fault occurs, the amplifier
channel is disabled after the detection delay. The side effect is that the fault
condition disappears since the channel's output power is null.
After 2 seconds, the channel is switched on and the cycle begins again
(unless the channel RF input signal is re-adjusted to meet the power
limitations).
BLA Extension Board 5.2.3
This board gives the information to the control board of RF detection.
Status Led Board 5.2.4
The status led board, on the front panel of the amplifier, displays overstress
functions, supplies status, and so on, as described in
"Indicators" on page 15
and "BLA Control Board" on page 25 .
BIS Board 5.2.5
The universal BIS board is located on the amplifier case and contains
identifications of the amplifier.
