hist ampl Histogram Amplitude
Definition: The difference in value of the two most populated peaks in a histogram. This
parameter is useful for waveforms with two primary parameter values, such as
TTL voltages, where hampl would indicate the difference between the binary
`1' and `0' voltage values.
Description: The values at the center (line dividing the population of peak in half) of the two
highest peaks are determined (see pks parameter description:). The value of
the leftmost of the two peaks is the histogram base (see hbase). While that of
the rightmost is the histogram top (see htop). The parameter is then
calculated as:
hampl = htop - hbase
Example:
In this histogram, hampl is 152 mV - 150 mV = 2 mV.
