{MWV_SEGMENT_LEVEL_OFFS:
(mandatory for multi segment waveforms)
The tag contains a list of level pairs in ASCII floating point format, one pair for every
segment in the multi segment waveform. The first value of a level pair defines the rms
offset and the second value the peak offset relative to the 16-bit full scale modulation
(-32767; + 32767) = 0 dB. The meaning of one level value pair is the same as in the
LEVEL OFFS
Example:
Usage:
{MWV_SEGMENT_FILES:
(optional for multi segment waveforms)
The tag contains a list of file names for every segment in the multi segment waveform
in ASCII format.
Example:
Usage:
{MWV_SEGMENTx_COMMENT: text}
(optional for multi segment waveforms)
The tag contains a user comment for a specific segment x = [0...NumOfSeg-1] in the
multi segment waveform in ASCII format.
Example:
Usage:
{CONTROL LIST WIDTH4–Length: #m0m1...mx...mM-1}
(optional for waveforms and multi segment waveforms)
The tag contains a binary marker element stream, which will be given out synchro-
nously to the I/Q sample sequence. One marker element mx consists of 4 bit, which
are assigned to the 4 possible marker lines of the instrument (one bit per marker line).
One 4 bit marker element is needed for every I/Q sample in the WAVEFORM tag - so the
number of marker elements M should be equal to the number of I/Q samples. The
CONTROL LENGTH tag has to contain the number of all marker elements M.

RMS level of segment 1 is 6dB below full scale. Peak level of
both segments is 0 dB full scale.
