PROBLEM TO BE SOLVED: To enable detection of an extremely subtle variation in statistical properties of a measured signal.SOLUTION: A test and measurement instrument converts digital data that represents an analog input signal into a time-domain bitmap, and then compares a density value in a region inside the time-domain bitmap to a density threshold. When the density value in the region violates the density threshold, a trigger signal is generated which causes digital data to be stored in a memory. |
