Abstract
A method for presenting information and a digital storage oscilloscope are disclosed in which primary measurements of a signal are performed and displayed. Parameters are also derived for the signal based upon the primary measurement data. These derived parameters are then also displayed as a function of time on the display, preferably with a common time axis. This enables the oscilloscope operator to correlate features found by reference to the derived parameters directly to the primary measurements of the signal. Moreover, since the data from the primary measurements are stored in the oscilloscope, multi parameter calculation and parameter recalculation can be performed.
