6.2.1 Pause Between Multiple Marked Samples
Due to the quantization of markers, a minimum pause between blocks of marked
samples is required to see the gap at the sample marker output.
Table 6-2: Pause between multiple marked samples
High Precision (Option -14B)
The table above shows the minimum gap size between blocks of multiple marked
samples/IQ sample pairs. If this condition is violated, it might be possible to get one
“combined marker” instead two individual markers.
6.2.2 Sample Marker in Looped Segments
Sample markers start always at the correct position. However, whenever loops are
involved in a block of continuously marked samples, the end position of the marker is
not well defined and may vary for some samples according to the following table.
Table 6-3: Sample Marker in Looped Segments
6.2.3 Sample Marker in Segments which are Addressed Offset Based
The instrument provides a mode where sequence table entries address the content of
segments by offset. Whenever a sequence table entry accesses a segment with an
offset not equal to zero (not starting from the beginning of the segment), this may result
in unexpected sample marker behavior like gaps when having marked the samples of
the data vector referenced by the offset value.
