Patent ID: 7933726

Claim:
A method of sampling a signal, the method comprising: providing the signal to a track and hold element; causing the track and hold element to perform a hold operation, thereby yielding a held signal exhibiting a substantially constant voltage level, wherein the act of causing the hold operation includes providing a track signal having a substantially predetermined shape to the track and hold element; providing the held signal to a signal measurement device; providing the track signal to the signal measurement device, so that the signal measurement device samples the track signal, and obtains at least one sample on an edge of the track signal; using the at least one sample and the predetermined shape of the track signal to determine a time value associated with the held signal; and wherein the signal measurement device associates the at least one sample of the edge of the track signal with a point in time, relative to a start of a data record, at which the sample was obtained, and wherein the act of using the at least one sample and the predetermined shape of the track signal to determine a time value associated with the held signal comprises: accessing a table to obtain an offset value, based upon the at least one sample of the edge of the track signal; and adding the offset value to the point in time associated with the sample of the edge of the track signal.
