Patent ID: 8046182

Claim:
A method comprising: digitally triggering a recording of one or more signals sampled at individual sampling times on a digital oscilloscope, wherein the digital triggering is implemented if the time difference between two occurring triggering events, which is determined from the number of sampling times between the two triggering events, overshoots or undershoots a time threshold, wherein an overshooting of the time threshold by the time difference is unambiguously identified, if the number of sampling times determined overshoots a first upper threshold, and the overshooting of the time threshold by the time difference is unambiguously not identified, if the number of sampling times determined undershoots a first lower threshold, wherein the undershooting of the time threshold by the time difference is unambiguously identified, if the number of sampling times determined undershoots a second lower threshold, and the undershooting of the time threshold by the time difference is unambiguously not identified, if the number of sampling times determined overshoots a second upper threshold, and wherein in the case of neither an unambiguous identification of an overshooting or undershooting of the time threshold by the time difference nor an unambiguous non-identification of an overshooting or undershooting of the time threshold by the time difference, the individual sampled values of the signals to be recorded on the digital oscilloscope are buffered and subjected to a subsequent fine analysis to determine if the time difference between the two triggering events overshoots or undershoots the time threshold.
