Patent ID: 7110898

Claim:
A method of data acquisition from a signal by a digital instrument having a bandwidth, comprising: (a) receiving a signal and associated trigger; (b) based on the associated trigger, sampling at multiple time intervals a plurality of signal values to create an acquisition record representing continuous fractional segment of the signal, the plurality of samples meeting Nyquist requirement for the bandwidth but in error according to at least one known error mechanism, and the plurality of samples being located time relative to the associated trigger; (c) subsequent to step (b), processing acquisition record with DSP techniques to produce compensated acquisition record corrected for the at least one known error mechanism; (d) repeating sequenced pairs steps (b) and (c) for a different continuous fractional segment of the signal at least once; (e) subsequent each instance of step (d), incorporating associated compensated acquisition record into resultant acquisition record as segment thereof corresponding to continuous fractional segment of signal whose signal values were sampled in associated instance of step (b); (f) receiving additional signal and additional associated trigger; and repeating steps (b) thru (e) for additional signal and additional associated trigger.
