Chapter 5 Post Processing IQC5000 Recorded Data
IQC5000 Recording Files
When recordings are offloaded from the IQC5000, 3 separate files (6 for dual channel recordings) are generated with
the following extensions:
 .xdat – Recording data file, 1 per channel(s) used during record
 .xhdr – Header file containing information about the recording (metadata)
 .xmrk – Marker data file containing time and location data
The xdat Data File
The .xdat data file is a binary data file with the following default format:
 I/Q Samples interleaved
 16-bit integer I, 16-bit integer Q
 Signed, Two’s Complement
 Little Endian
This and further information about the .xdat data file is recorde
d in the .xhdr header file.
The xhdr Header File
The .xhdr file is of XML 1.0 format and contains information about the recorded data. The format is detailed in
Figure 54 on page 65.
Note: The .xhdr file should be parsed as XML, not strictly as text, as e
scape characters are used where the
XML standard requires them.
