Introduction
The DSP exciter contains a microprocessor that allows remote or local control of the exciter
and consolidates logic for varying degrees of PA control and monitoring through a video
display terminal (VDT). Operating characteristics of the exciter are controlled by the
selection of hardware options. It is frequency selectable by specifying the appropriate
internal frequency determining hardware and software. It is also capable of communicating
with several operating protocols through the proper selection of interface boards.
