Value
Description
SignalHardwareRecordLength
Number of samples actually available in this waveform, including the
number of required samples in the waveform and the additional samples
needed for further computation
LeadingSettlingSamples
Relevant only for BIN files. In XML and CSV files, the value is 0.
Number of additional samples before the beginning of waveform sam-
ples. These additional samples are needed for further computation, for
example, for filters.
Horizontal system
TimeScale
Horizontal scale in seconds per division
HorizontalDivisionCount
Number of horizontal divisions
RescaleCenterTime
Horizontal position, the time distance between the reference point and
the zero point of the diagram
RescaleCenterPoint
Position of the reference point in % of the screen
ReferencePoint
Position of the zero point in % of the screen
TriggerOffset
Time distance from the trigger point to the zero point of the diagram
XStart
Horizontal start value of the waveform (time or frequency) *)
XStop
Horizontal stop value of the waveform (time or frequency)
HardwareXStart
Actual horizontal start value of data, including the settling time for further
computation *)
HardwareXStop
Actual horizontal stop value of data, including the settling time for further
computation
*) If the waveform is a spectrum, the XStart and HardwareXStart values
may be slightly smaller than the specified start frequency, or even get
negative. The spectrum is centered on the center frequency, and the fre-
quency range covered by one spectral bin is given by the SignalResolu-
tion. Hence, the spectral bin in the center of the spectrum always covers
the range [CenterFrequency; CenterFre SignalResolution[. As a
result, the range covered by the first spectral bin in the spectrum may
reach further than the specified start frequency. It is ensured that the
specified start frequency is included in the frequency range.
Vertical system
If multiple channels are exported, the values of channel1 are delivered, no matter if channel 1 is exported
or not.
VerticalScale
Vertical scale of the waveform in Volts per division, or other unit / division
VerticalDivisionCount
Number of vertical divisions
VerticalPosition
Vertical position of the waveform in divisions
VerticalOffset
Vertical offset of the waveform in Volts, or other unit
NofQuantisationLevels
Theoretical number of quantization levels in the signal. This value
depends on the waveform format (8 bit, 16 bit, …). In case of a math
waveform, it depends on the quantization levels of the operands and on
the operator type.
BaseYStart
Vertical start value of the waveform
