Claim Text:
1. A system for synchronizing multiple arbitrary waveform generators comprising: a master arbitrary waveform generator (AWG) having a master AWG clock and a master digital to analog converter (DAC); one or more slave arbitrary waveform generators (AWGs), each having a slave clock and a slave digital to analog converter (DAC); a sync hub having a sync controller and sync phase detector; a signal path between the master DAC and the sync phase detector and between the master DAC and sync controller, and between the slave DAC and sync phase detector; wherein said master DAC is configured to generate a divided down clock (SystemRefClock) from the master AWG clock and output said SystemRefClock to said sync hub; wherein the one or more slave DACs are configured to align the phase of the slave clock to the phase of said SystemRefClock; and an output on the sync hub to the master AWG and one or more slave AWGs configured for outputting a clock signal (SystemClock) derived from said SystemRefClock, said SystemClock being used within the AWGs to indicate when to start playing waveforms from the AWGs.
