A.2.2 I/Q Data Binary File
The I/Q data is saved in binary format according to the format and data type specified
in the XML file (see Format element and DataType element). To allow reading and
writing of streamed I/Q data, all data is interleaved, i.e. complex values are interleaved
pairs of I and Q values and multi-channel signals contain interleaved (complex) sam-
ples for channel 0, channel 1, channel 2 etc. If the NumberOfChannels element is not
defined, one channel is presumed.
Example: Element order for real data (1 channel)
I[0],
I[1],
I[2],
...
Example: Element order for complex cartesian data (1 channel)
I[0], Q[0],
I[1], Q[1],
I[2], Q[2],
...
Example: Element order for complex polar data (1 channel)
Mag[0], Phi[0],
Mag[1], Phi[1],
Mag[2], Phi[2],
