摘要
A time stamping method for threshold crossing points of an input signal uses a dithered threshold level. Digital data samples are acquired for the input signal and time marks are determined for the threshold crossings using interpolation. The time marks are stores as the time stamps. A threshold offset value generator generates a distribution of offset values for dithering the threshold value. Time interval values are generated from the time stamps and the number of occurrences of time interval values are accumulated in time bins. A time interval distribution histogram and statistical time interval distribution data, such as the mean, standard deviation and minimum and maximum time intervals may be generated.
