System Components
There is, however, a built in delay of two minutes and twenty seconds before
the reset condition can occur to allow adequate cooling for an excessively hot
ambient condition. The microprocessor also has a software threshold to
determine the minimum acceptable output power for a normal transmit
condition. When the output power is below this limit a fault indications
provided (i.e. low power), but otherwise the amplifier operates normally. This
low power threshold is normally set in software to 50% of full rated power
unless the customer makes a special request.
In addition to its normal control functions, the Power Amplifier Control Board
also contains all the drive circuitry for the on-board displays as well as the
circuitry for the front panel display.
