The waveform histogram export saves data in two files. The *.Wfm.* file contains 256
or 512 absolute or relative histogram values. The other file is the header file.
Contents of the header file:
●
Source waveform of the histogram
●
Histogram mode: vertical or horizontal
●
Incidence of exported values: absolute or relative
●
Histogram range: XStart, XStop, YStart, YStop
●
Name of the exported histogram
Data conversion:
Using the header data, you can calculate the waveform value to which a histogram
value belongs:
YV
alue = (YStop - YStart) / HistogramV
aluesCount * HistogramValueNumber + YStart
YStart -0.25 V
YStop 0.25 V
HistogramValuesCount 256 (total number of written rows in a CSV file)
HistogramValueNumber 68 (number of the row in a CSV file)
Y-Value (0.25 - (-0.25)) / 256 * 68 - 0.25 = -0.11719 V
