发明名称 Integrated superconducting sampling oscilloscope.
摘要 <p>An Integrated Superconductor Sampling Oscilloscope may include a sampling gate utilizing superconductor devices such as a Josephson junction device as well as external circuitry for producing a visual representation of an input signal responsive to the output of the sampling gate. The oscilloscope may further comprise an attenuator for receiving the input signal, a trigger recognizer comprising superconductor devices which produces a pulse signal when the input signal from the attenuator exceeds a threshold level, a hold-off gate which produces an output signal when the pulse signal from the trigger recognizer is produced concurrently with a gating event, and electrical variable delay which may comprise superconducting devices and produces a delayed pulse signal in response to an output signal by the hold-off gate and a strobe pulse generator which produces a signal to the sampling gate in response to the pulse signal from the electrical variable delay output. The result is an oscilloscope achieving a low jitter trigger from the input signal itself so as to allow viewing of the leading pulse of an input signal.</p>
