Abstract: A device is capable of receiving a waveform and capturing acquisitions of the waveform. Different boundary masks can be applied to the waveform acquisitions, depending on the timing of the acquisition. When a timing interval finishes, a different dynamic boundary mask can be loaded from memory. Boundary masks can include any number of segments, and can be used whenever desired.
