Flash waveform analyzer method and device

A flash waveform analyzer, comprising:

• a transmission line for carrying a signal;
• a plurality of samplers within said transmission line for measuring a characteristic of said signal at different points of said transmission line;
• a strobe source for providing a strobe pulse;
• and
• a plurality of separate delay lines, each separate delay line providing said strobe pulse to activate each sampler, wherein said signal has a propagation velocity slower than a propagation velocity of said strobe pulse to allow for identical electrical lengths despite unequal physical lengths of said separate delay lines to each sampler in order to simultaneously activate said samplers.

A method of analyzing a waveform, comprising the steps of:

• introducing a signal within a transmission line;
• measuring a characteristic of the signal at different points along the transmission line;
• and
• varying a propagation velocity of the signal such that the strobe pulse propagates faster than the signal to maintain equal propagation delays of the separate delay lines despite unequal physical lengths.
