Abstract

A method and apparatus for determining a trigger in a test and measurement apparatus are provided. The method includes the steps of indicating one or more anomalies to be found, loading a first trigger configuration to the test and measurement apparatus and determining for a first predetermined time period whether an input signal generates a trigger related to one or more of the one or more anomalies. A second trigger configuration is loaded to the test and measurement apparatus upon the conclusion of the first predetermined time, and for a second predetermined time it is determined whether the input signal generates a trigger related to one or more of the one or more anomalies.
