Optimum Phase Coherence Between Multiple RF Outputs
应用文章
This application note describes the achievable channel-to-channel phase coherence of two G2 Signal Generators (AP5002A) or two FS2 Frequency Synthesizers phase locked to an external 10 MHz reference.
Keysight synthesized signal generators are now available up to 26 GHz while enabling tight stability, phase coherency, and extremely fast tuning speeds. Keysight RF synthesizers are standalone units with an integrated precision 100 MHz OCXO, but external programmable 1 to 250 MHz references can be used for phase lock. Some applications require phase coherence to an external reference, particularly between multiple RF channels.
