Name Definition
Waveform Count Displays the number of waveforms that have contributed to the histogram.
Peak Hits Displays the number of points in the largest bin of the histogram.
Pk-Pk Displays the peak-to-peak value of the histogram. Vertical histograms display the “voltage” of
the highest nonzero bin minus the “voltage” of the lowest nonzero bin. Horizontal histograms
display the “time” of the rightmost nonzero bin minus the “time” of the leftmost nonzero bin
(Max -- Min).
Max Displays the maximum voltage or time.
Min Displays the minimum voltage or time.
Mean 1 StdDev The percentage of points in the histogram which are within 1 standard deviation of the
histogram mean.
Mean 2 StdDev The percentage of points in the histogram which are within 2 standard deviations of the
histogram mean.
Mean 3 StdDev The percentage of points in the histogram which are within 3 standard deviations of the
histogram mean.
