PROBLEM TO BE SOLVED: To provide a simplified method for describing a regular expression.SOLUTION: A test and measurement instrument includes a user interface 1020 and a controller 1005. The controller 1005 is configured to receive a serial bit stream 10 and apply a logic 1010 to the serial bit stream 10 to identify states within the serial bit stream 10. The result of applying the logic 1010 to the serial bit stream 10 is a combined state/bit stream. A regular expression can be applied to the combined state/bit stream: the regular expression can include state information 1025. The controller 1005 is also configured to present output data through the user interface 1020 in response to the application of the regular expression to the combined state/bit stream.SELECTED DRAWING: Figure 10 |
