The instrument’s parameter buffer is very effective for determining the optimal number of bins to
be used. An optimal bin number is one where the change in parameter values is insignificant, and
the histogram distribution does not have a jagged appearance. With this buffer, a histogram can
be dynamically redisplayed as the number of bins is modified by the user. In addition, depending
on the number of bins selected, the change in waveform parameter values can be seen.
In the next figure, the histogram shown in the previous figure has been recalculated with 100
bins. Note how it has become far less jagged, while the real peaks are more apparent. Also, the
change in sigma is minimal (6.750 ps compared with 6.8 ps).
