12.2.3.2 Reference waveforms
The REF format is a specific format, which allows you to reload the waveform data as
reference waveform. The data is saved in a zipped file that contains two files. One file
is a binary file (BIN file) and contains the waveform data values. The second file is an
XML file and contains the header data in several data groups. Header data is required
to reload the waveform from data, or to analyze the data values of the data file.

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).
Save and recall waveform data
