• Creates a marker file and places the marker information, bits 14 and 15 of the E443xB I data,
into the marker file for markers one and two. Markers three and four, within the new marker file,
are set to zero (off).
• Interleaves the 16–bit I and Q data creating one I/Q file.
• Creates a file header with all parameters set to unspecified (factory default file header setting).
