Table 8-8: Histogram measurements
Meas. type
Description/Result
n
Waveform count
The number of acquisitions (waveforms) the histogram is based on
S
Waveform samples
The number of samples from the most recent acquisition included in the
current histogram
S
Histogram samples
The number of samples from all acquisitions included in the current his-
togram
Histogram peak
The maximum count value in the histogram
Peak value
The signal value at the histogram peak
Upper peak value
The signal value at the maximum count value in the upper half of the
histogram
Lower peak value
The signal value at the maximum count value in the lower half of the
histogram
Maximum
The highest signal value with a probability > 0
Minimum
The lowest signal value with a probability > 0
Median
The signal value for which half the samples lie above, the other half
below in the histogram
The sample count of one signal value after the other are accumulated
until half the total number of samples in the histogram is reached. The
signal value for which 50% of the samples are accumulated is the
median.
Max - Min
The range of signal values with a probability > 0
Mean
The weighted arithmetic average of the histogram
σ
σ (S-dev)
Standard deviation of the sample numbers
