Return the values of the power dynamics traces. Each value is sampled with 48 T
s
,
corresponding to 1.5625 µs. The results of the current, average and maximum traces
can be retrieved.

2048 power values, from -1100 µs to +2098.4375 µs relative to
the start of the measure subframe. The values have a spacing of
1.5625 µs. The 705
th
value is located at the start of the "Mea-
sure Subframe" (0 µs).
The diagram at the display shows only a subsection of this trace,
depending on the selected time mask.
