{MWV_SEGMENT_LEVEL_OFFS:
RMSOffs_dBSg0,PeakOffs_dBSg0, …, RMSOffs_dBSgN-1, PeakOffs_dBSgN-1}
(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
Example:
{MWV_SEGMENT_LEVEL_OFFS: 3.0,0.0,6.0,0.0}
2 segments: RMS level of segment 0 is 3dB below full scale;
RMS level of segment 1 is 6dB below full scale. Peak level of
both segments is 0 dB full scale.
Usage:
Setting only
{MWV_SEGMENT_FILES:
“FileNameSeg0.wv”, “FileNameSeg1.wv”, …, “FileNameSegN-1.wv”}
(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:
{MWV_SEGMENT_FILES: "/var/user/sine.wv",
"/var/user/rect.wv"}
Usage:
Setting only
{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:
{MWV_SEGMENT1_FILES: segment 1 contains a QPSK
signal.}
Usage:
Setting only
{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.
