Value Description
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
BaseYStop Vertical stop value of the waveform
Multi channel export
The header files contain strings like this: MultiChannelVerticalOffset:
4:1.63:1.96:0:0:1e-005:0:-1e+026:1e+026:1e-005:10:0:V:. Only the first 5 values and the
unit at the end of the string are relevant for data analysis. All other values are for internal use and not
explained here.
Examples are in csv format.
MultiChannelExport Indication whether multiple channels are exported simultaneously: On |
Off
MultiChannelExportState Number of channels and export status of the individual channels, for
example, 4:On:Off:On:On...: channels 1, 3 and 4 are exported.
MultiChannelVerticalOffset Number of channels and vertical offset of the individual channels, for
example, 4:0:0:0.02:0...: channel 3 has an offset of 20 mV.
MultiChannelVerticalPosition Number of channels and vertical position of the individual channels, for
example, 4:0:0:0:2...: the position of channel 4 is 2 divisions.
MultiChannelVerticalScale Number of channels and vertical scale of the individual channels, for
example, 4:0.05:0:0.03:0.04...: scale of channel is 50 mV/div, channel 3
has 30 mV/div and channel 4 has 40 mV/div.
MultiChannelBaseYStart Number of channels and minimum value of the vertical range for each
individual channel, for example, 4:-0.25:0:-0.13:-0.28...
MultiChannelBaseYStop Number of channels and maximum value of the vertical range for each
individual channel, for example, 4:0.25:0:0.17:0.12...: The range of chan-
nel 1 is -250 mV to 250 mV. The range of channel 3 is -130 mV to
170 mV. The range of channel 4 is -280 mV to 120 mV.
History
TimestampState State of the timestamps export. If on, the timestamps of each history
waveform are written to the waveform data file.
Math waveform
BaseUnit Base unit of a mathematic waveform, for example, linear unit
ViewUnit User-selected unit of a mathematic waveform, for example, logarithmic
unit for a spectrum. The value is only valid if the exported waveform is a
math waveform.
ViewUnitRelative Indication of a relative unit. It is true if the math waveform has the ViewU-
nit "dB", for example. The value is only valid if the exported waveform is
a math waveform.
ViewReferenceLevel Reference level for a relative unit. The value is only valid if the exported
waveform is a math waveform, and the unit is relative.
FFT
CenterFreq Center frequency of the spectrum
