Abstract
Abstract Disclosed is a probability density histogram display for a digital oscilloscope which shows a probability density histogram display of an input signal waveform alongside the conventional voltage-versus-time time-domain display of the waveform. The histogram shows the relative frequency of occurrence of voltage amplitude levels of the waveform. The histogram is optional and shown simultaneously with the time-domain display of the waveform.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
148 words
A digital oscilloscope for acquiring and displaying information about an electronic input signal to said oscilloscope, said information to be presented in both the time-domain and the probability-domain simultaneously on a display-screen of said oscilloscope, said oscilloscope comprising: a first means for displaying, in said time-domain, said input signal as a voltage-versus-time waveform within a distinctly demarcated first portion of said display-screen of said oscilloscope; and a second means for displaying, in said probability-domain, within a distinctly demarcated second portion of said display-screen, a probability-density histogram, said histogram showing the relative frequency of occurrence of the voltage amplitude levels of said voltage-versus-time waveform, said histogram viewable simultaneously with said voltage-versus-time waveform; said oscilloscope being configured such that a user of said oscilloscope can adjust acquisition of said input signal in response to information obtained from visually comparing the probability-domain display with the time-domain display of said input signal.
Claim 2
Dependent Claim
