Abstract
In novel sampling methods and apparatus, a repetitive waveform is sampled at a sampling phase which alternates at a phase alternation frequency between a fixed reference phase and a variable phase while changing the variable phase progressively and periodically. The amplitude of a component of the resulting signal at the phase alternation frequency is detected to derive a lower frequency analog of the sampled waveform. The sampling methods and apparatus are particularly useful for electro-optic sampling of very high frequency waveforms in semiconductor devices.
