摘要： The time stamping method for an input signal generates time marked digital data values as a reference edge and defines at least a first time stamp in the reference edge. Digital data samples of the input signal are acquired to create a waveform record of the input signal. The digital data samples of a waveform record edge are compared to time equivalent digital data values of the reference edge to generate a error value representative of the difference between the waveform record edge and the reference edge. A time offset value is generated from the error value to vary the time location of the reference edge and the comparison and time offset generating steps are repeated to minimize the error value. The time offset value at the minimum error value is combined with a time location of nearest digital data sample of the waveform record edge to generate a waveform record edge time stamp.

摘要： Embodiments of this invention include a test and measurement instrument and associated methods for acquiring and stitching wide overlapped non-uniform frequency bands so that a user specified band can be efficiently displayed and analyzed. The test and measurement instrument includes a user interface to receive the user specified frequency span. Acquisition circuitry acquires one or more predefined frequency bands having non-uniform overlapping frequency ranges. A frequency band processing section can decimate the acquired frequency bands, mask the acquired frequency bands, and stitch the masked frequency bands together. A display section displays the user specified frequency span using the stitched frequency bands. Due to the overlap configuration of the wide non-uniform bands, any user specified span between 50 kHz and 6 GHz, or thereabout, can be covered by two bands.

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.

摘要： A test and measurement instrument acquires a signal from a device under test, displays that signal as a source waveform, and makes measurements on that source waveform with regard to a predetermined property or event. The test and measurement instrument employs the method of the subject invention for placing these measurements into a waveform and directly correlating a position in the measurement waveform to the same area on the source waveform where they were measured. Specifically, the subject invention displays the correlation of points on a source waveform and a measurement waveform without requiring the use of a common horizontal time scale. In one embodiment of the invention, the measurement waveform is a histogram and a pointer to a given location in the histogram causes identification of corresponding areas in the source waveform.

摘要： A variable coefficient, non-separable spatio-temporal interpolation filter is used to deinterlace an interlaced video signal to produce a progressive video signal. The interlaced video signal is input to a video memory which in turn provides a reference and plurality of offset video signals representing the pixel being interpolated and spatially and temporally neighboring pixels. A coefficient index, transmitted with the interlaced video as an auxiliary signal, or derived from motion vectors transmitted with the interlaced video, or derived directly from the interlaced video signal, is applied to a coefficient memory to select a set of filter coefficients. The reference and offset video signals are weighted together with the filter coefficients in the spatio-temporal interpolation filter, such as a FIR filter, to produce an interpolated video signal. The interpolated video signal is interleaved with the reference video signal, suitably delayed to compensate for filter processing time, to produce the progressive video signal.
