"WebSep 21, 2024 · Finally, direct RF sampling architectures can also simplify synchronization. For example, to achieve phase coherence for RF systems, you must synchronize the internal clocking of the RF instruments as well as the LOs. In direct sampling, which requires no LOs, you can focus only on the clock synchronization of the devices. " - Synchronized bandpass sampling
