摘要： One or more systems, devices, and/or methods provided herein relate to a process for in-process radio frequency (RF) signal quality analysis and amplitude adjustment of one or more RF devices. In one or more embodiments, the RF device can comprise a portion of a quantum computing system, such as of readout electronics thereof, and thus amplitude adjustment can be at a waveform generator that generates pulses to affect one or more qubits of a quantum logic circuit of the quantum computing system. Generally, an electronic device can comprise an RF tap connected to an RF signal component of a first RF signal chain, and an analysis component connected to the RF tap, the analysis component configured to convert an RF signal from the RF signal component and to compare a conversion result thereof to an expected power output that is based on historical data for a second RF signal chain.
