Abstract:
1. A method for defining a common time base suitable for use in connection with the operation of a multi-link protocol analyzer in a multi-protocol communications system, the method comprising: determining a first protocol clock frequency at a first link analyzer of the multi-link protocol analyzer, the first protocol clock frequency being associated with a first communications protocol associated with the multi-protocol communications system; determining a second protocol clock frequency at a second link analyzer of the multi-link protocol analyzer, the second protocol clock frequency being associated with a second communications protocol associated with the multi-protocol communications system, wherein the second protocol clock frequency is unrelated to the first protocol clock frequency; and using the first and second protocol clock frequencies as a basis for determining a reference clock frequency, where the reference clock frequency is different from each of the first and second protocol clock frequencies, wherein using the first and second protocol clock frequencies as the basis for determining the reference clock frequency comprises selecting a reference clock frequency that is an integer multiple of each of the first and second protocol clock frequencies.
