High frequency electric signal sampling device for use in pulse metrology, has second sampling stage in series with first stage, second sample being representative of the first sample and having a lifetime greater than that of the first

摘要

Device comprises a first stage (A1, I1, C1), which is used to take a first signal sample at a first instant in time and one or more second stages (A2, I2, C2), in series with the first, for taking a second sample from the first sample at a second instant of time greater than the first, with the second sample being representative of the first sample and having a lifetime greater than that of the first sample. An Independent claim is also included for a sampling system.
