– Event count per point: number of measurement results that creates one long-
term point
– Waveform count per point: number of waveforms included in one long-term
point.
Measurement histogram: The *.Wfm.* file contains 1000 absolute or relative histo-
gram values.
Data conversion of measurement histogram data:
Using the header data, you can calculate the measurement value to which a histogram
value belongs:
MeasValue = (XStop - XStart) / 1000 * HistogramValueNumber + XStart
Example: The 273rd histogram value is 0.491749. That means, the relative frequency
of the measurement value 0.1246 V is 0.491749.
XStart 0.07 V
XStop 0.27 V
HistogramValueNumber 273 (number of the row in a CSV file)
MeasValue (0.27 - 0.07) / 1000 * 273 + 0.07 = 0.1246 V
