15.13.2 Transfer of Waveform Data
Data conversion of integer values if FORMat:DATA INT,16 is used
To convert INT16 data to physical quantities, e.g. voltages, use the following formulas:
PhysicalQuantity = ( Value_ADC * ConversionFactor ) + VerticalOffset
eff
ConversionFactor = VerticalScale * VerticalDivisionCount / NofQuantisationLevels
VerticalOffset
eff
= VerticalOffset – VerticalPosition * VerticalScale
Table 15-1: Data conversion example
VerticalScale 0.05 V/div
VerticalOffset 0.1 V
VerticalPosition 1 div
NofQuantisationLevels 255 * 256
VerticalDivisionCount 8
Value_ADC -61
ConversionFactor 0.05 * 8 / (255 * 256) = 0.000006127451 V
VerticalOffset
eff
0.1 - 1 * 0.05 = 0.05 V
Voltage (-61 * 0.000006127451 V) + 0.05 V = -0.32 mV
The values are read with CHANnel<m>:DATA[:VALues]?.
To get the vertical scale, position and offset, you can use the appropriate commands:
●
CHANnel<m>:SCALe on page 300
●
CHANnel<m>:POSition on page 302
●
CHANnel<m>:OFFSet on page 302
You can finde these values also in the data export file, see Chapter 15.13.1, "Export of
Waveform Data to File", on page 489.
