{MWV_SEGMENT_CLOCK_MODE: Mode}
(mandatory for multi-segment waveforms)
The tag contains a string in ASCII format which supplies the clock rate mode, that was
used for calculation of the multi-segment output waveform.
The tag CLOCK contains always the highest clock rate of all segments.
The tag MWV_SEGMENT_CLOCK contains the clock rates of the individual segments.
Setting parameters:

Example:
Usage:
{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.

UNCHANGED
The segments can have different clock rates.
During the multi-segment calculation, the clock rates of all indi-
vidual original waveforms were taken over unchanged in the
segments of the multi-segment output waveform (no software
resampling is done).
If the segments have different clock rates, there are some
restrictions on signal output, i.e. switching per external trigger
and seamless switching between segments is not possible.
If all segments have already an identical clock rate, this mode is
usually set to HIGHEST.
HIGHEST
All segments have an identical clock rate, which is the highest
clock rate of all original waveforms.
If the original waveform has a lower clock rate, the instrument
upsamples to the highest clock rate when calculating the multi-
segment output waveform.
USER
All segments have an identical clock rate, which is given by the
user.
Note: Only upsampling is allowed, no downsampling.
If the original waveform has a lower clock rate, the instrument
upsamples to the highest clock rate when calculating the multi-
segment output waveform.
