Operating Manual 1176.8016.02 ─ 17
Setting parameters:
Mode
UNCHANGED
The segments may 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 indentical clock rate, which is the highest
clock rate of all original waveforms.
If an individual original waveform has a lower clock rate, an
upsampling to the highest clock rate will performed on calcula-
tion of the multi segment output waveform.
USER
All segments have an indentical clock rate, which is given by the
user.
Note: Only upsampling is allowed, no downsampling!
If an individual original waveform has a lower clock rate, an
upsampling to the user clock rate will performed on calculation
of the multi segment output waveform.
Example:
{MWV_SEGMENT_CLOCK_MODE: UNCHANGED}
{MWV_SEGMENT_CLOCK_MODE: HIGHEST}
{MWV_SEGMENT_CLOCK_MODE: USER}
Usage:
Setting only
{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.
