Yes, Berkeley Nucleonics high-performance arbitrary waveform generators can be synchronized together using clock input and output connections. Compatible models include the 670C, 675, 685, 685C, and 686. You can synchronize up to 4 AWG units, providing a maximum of 32 analog channels and up to 128 digital channels (depending on model and installed licenses). Synchronization is achieved through shared clock signals that maintain phase alignment across all channels, which is essential for applications in phased array testing, multi-channel RF simulation, and coherent signal generation.
