A cable connector for counting a number of plug-in events and preventing further plug in attempts after a threshold number of plug-in events have occurred. An inner sleeve is located inside an outer sleeve, and is designed to move relative to the outer sleeve. The inner sleeve further includes a tab on an outer surface of the inner sleeve. A gear wheel is located inside the outer sleeve and perpendicular to the inner sleeve and has a number of gear teeth. A toggle plug counter rotates the gear wheel one tooth in response to a plug-in action of the cable counter. When the gear wheel rotates to a point where the tab aligns with a notch in the gear wheel an inner spring at the opposite end of the inner sleeve causes the inner sleeve to move through the gear wheel such that further plugging action becomes difficult.

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.

Radio frequency signal integrity verification

An apparatus includes a sampling circuit, a sense circuit, and a tuning circuit. The sampling circuit samples an input signal according to a sampling clock signal to produce a sampled signal. The sense circuit determines a scaling factor based on a distortion in the sampled signal caused by the sampling clock signal. The tuning circuit generates an offset signal based on the sampling clock signal and the scaling factor. The offset signal reduces the distortion in the sampled signal caused by the sampling clock signal.
