Phase synchronising two generators
Two generators can be synchronised together to provide outputs at the same frequency (or harmonics) and with a phase difference. The amplitude and phase of these outputs can also be modulated providing the capability to perform QAM and QPSK respectively. It is also possible to synchronise more than two generators but results are not guaranteed.
