Abstract: A system and method synchronizes multi-AWG system, where such systems are of a type having a master arbitrary waveform generator (AWG), one or more slave AWGs, and a sync hub having a sync controller and sync phase detector. The method operates by receiving at the sync hub a divided down clock (SystemRefClock) signal from a master arbitrary waveform generator (AWG). The method then derives a clock signal (SystemClock) from the SystemRefClock signal received from the master AWG and outputs the SystemClock signal to the master AWG and to the one or more slave AWGs Finally, the SystemClock signal is used to clock a synchronous trigger for the master AWG and one or more slave AWGs to play a waveform. In one aspect, the synchronous trigger includes AlignmentFiducial and Run signals to effect trigger and play commands.

Abstract: A method and apparatus for processing packetized data spanning multiple clock cycles includes at least one comparator, for comparing a present clock cycle count to a reference clock cycle count, wherein the reference clock cycle values may be anywhere within the packet and may be non-contiguous with other reference clock cycle values. At least one word recognizer, compares a presently clocked word to a reference word, and an output circuit provides an indication of a favorable word comparison that occurred in response to a favorable clock cycle count comparison.
