Abstract
The present invention is generally directed to a digital oscilloscope and associated method that provides a peak detect mode of operation that not only accurately displays peak information, but also reflects the significance of peak information, without distorting a statistical view of the signal. In this regard, and in accordance with one aspect of the invention, the oscilloscope includes an analog to digital (A/D) converter configured to periodically sample an input signal and convert the periodic samples into a train of digital data. A circuit is disposed at the output of the A/D converter and is configured to evaluate the train of digital data over a first predetermined period of time and detect a minimum value and a maximum value during the first period of time. A mechanism is configured to evaluate the minimum and maximum values and determine a significance measure of the minimum value and the maximum values. Finally, the oscilloscope includes a display controller configured to vary an intensity of a signal representation on a display, in response to the significance measure.
