Abstract

See full text

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.
