Histogram Parameters

Once a histogram is defined and generated, measurements can be performed on the histogram

itself. Typical of these are the histogram’s:

• Average value, standard deviation

• Most common value (parameter value of highest count bin)

• Leftmost bin position (representing the lowest measured waveform parameter value)

• Rightmost bin (representing the highest measured waveform parameter value).

Histogram parameters are

provided to enable these

measurements. Accessible

by selecting Statistics

from the Select

Measurement menu, they

are calculated for the

selected waveform section

between the parameter

cursors:

avg average of data values in histogram

fwhm full width (of largest peak) at half the maximum bin

fwxx full width (of largest peak) at xx% the maximum bin

hampl histogram amplitude between two largest peaks

hbase histogram base or leftmost of two largest peaks

high highest data value in histogram

hmedian median data value of histogram

hrms rms value of data in histogram

htop histogram top or rightmost of two largest peaks

low lowest data value in histogram
