Abstract
In a communications or jamming system, accurate timing for the control of the frequency, amplitude, modulation type, pulse repetition rate or other transmit characteristics is achieved for the transmission of digitally processed packetized signals through the use of standard non-realtime off-the-shelf components for the digital processing and a realtime interface which reads transmit chain headers and, with the assistance of a precise time reference, assures that the transmit chain is configured in time to transmit the packets. Note that the realtime interface assures nanosecond timing accuracy regardless of timing errors introduced by the off-the-shelf components used in upstream digital processing.
