Value Description
SignalAttributes
Same values as in CSV files, except for Model and SerialNumber. See Table 12-1.
SignalAttributesPostProcessing
SignalFormat Format of the data values in the BIN file: INT8BIT, INT16BIT,
INT32BIT, FLOAT, DOUBLE
Origin WFM_EXPORT: export of one acquisition
ByteOrder
Byte order of the values in the BIN file
●
LSB first: little endian, least significant byte first
●
MSB first: big endian, most significant byte first
NumberOfWaveforms Number of waveforms, = 1
TimestampState OFF
Timestamp Absolute time of the waveform recording in ISO 8601 format
DecimationMode Method to reduce the number of data samples to achieve the
required sample rate
IsMinMax If ON, then min and max values are saved for each sample. For
envelope and peak detect waveforms.
IsComplex If ON, then two values are saved for each sample (I and Q value).
TriggerOffsetToPostSampleInSec-
onds
Offset between the exact trigger position and the first sample after
the trigger
SignalRecordLength Number of samples in the BIN file. If the signal is a spectrum, the
value indicates the number of FFT bins.
SignalXStart Time of the first sample in the acquired data. Different from XStart if
only part of the data is exported.
SignalXStop Time of the last sample in the acquired data. Different from XStop if
only part of the data is exported.
AdjustedResolutionBW Actual resolution bandwidth of a spectrum waveform. Only valid if the
exported waveform is a spectrum.
NoiseBandwidth Noise bandwidth of a spectrum waveform, required for power calcu-
lation. Only valid if the exported waveform is a spectrum.
ValuesPerSample Number of y-values saved at each sampling time. The value is usu-
ally 1. The value is 2, if min and max values are saved for each sam-
ple, for example, for envelope waveforms.
NofQuantisationLevels Number of quantization levels of y values
TOADone If ON, then TriggerOffsetToPostSampleInSeconds is compensated.
SignalResolution Time between two samples in this waveform. The value can differ
from Resolution if the source is, for example, a spectrum. The value
is determined automatically considering the waveform parameters
and their dependencies. If the signal is a spectrum, the value indi-
cates the frequency range of FFT bins.
HorizontalDomain Domain of the x-axis (TIME or FREQUENCY)
