Histogram measurements (cont.)
Measurement Description
Peak-to-peak
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 rightmo st nonzero bin minus the time of the leftmost
nonzero bin.
Histogram Max
Displays the voltage of the highest nonzero bin in vertical histograms o r the time of the
rightmost nonzero bin in horizontal histograms.
Histogram Min
Displays the voltage of the lowest nonzero bin in vertical histograms or the time of the
leftmost nonzero bin in horizontal histograms.
Histogram
Mean
Measures the average of all histogram data points within or on the histogram box.
Standard
Deviation
Measures the standard deviation (Root Mean Square (RMS) deviation) of all histogram
data points within or on the histogram box.
Sigma1 Displays the percentage of the hits in the histogram that are w ithin one standard deviation
of the histogram mean.
Sigma2 Displays the percentage of the hits in the histogram that are within two standard
deviations of the histogram mean.
Sigma3 Displays the percentage of the hits in the histogram that are within three standard
deviations of the histogram mean.
Customizing an Automatic Measurement
You can customize automatic measurements by using gating, modifying measurement statistics, adjusting the measurement
ref
erence levels, or taking a snapshot.
Gating
Gating confines the measurement to a certain portion of a waveform. To use:
1. Push Measure.
2. Push More as many times as needed to
select Gating from the resulting pop-up
menu.
