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
