{MWV_SEGMENT_CLOCK: ClockSeg0, ClockSeg1, …, ClockSegN-1}
(mandatory for multi-segment waveforms)
The tag contains a list of clock frequencies for every segment in the multi-segment
waveform in ASCII floating point format.
Example:
{MWV_SEGMENT_CLOCK: 100e6,80e6}
2 segments: clock of segment 0 is 100 MHz, clock of segment 1
is 80 MHz.
Note:
If the segments have different clock frequencies, there are
some restrictions on signal output, i.e. seamless switching
between segments is only possible, if all segments have the
same clock frequency. Software resampling (upsampling) can be
used to bring all segments to the same clock.
Usage:
Setting only
{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
tag for normal waveforms.
Example:
{MWV_SEGMENT_LEVEL_OFFS: 3.0,0.0,6.0,0.0}
2 segments: RMS level of segment 0 is 3 dB 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: "d:\waveforms\sine.wv", "d:
\waveforms\rect.wv"”}
Usage:
Setting only
{MWV_SEGMENTx_COMMENT: text}
(optional for multi-segment waveforms)
