Waveform Copy
The Copy math function makes a copy of your present waveform in its unprocessed state. While
processing may continue on the original waveform, the copy enables faster throughput in some cases by
preserving the original data. That is, no calculations need to be undone on the copy before additional math can be
calculated.
This benefit of faster throughput, however, comes at the expense of memory usage.
Waveform Sparser
The Sparse math function allows you to thin out an incoming waveform by skipping points at regular
intervals, and by starting acquisition at a particular offset (point). The Sparsing factor specifies the number of
sample points to reduce the input waveform by. A sparsing factor of 4, for example, tells the oscilloscope to retain
only one out of every 4 samples. A
Sparsing offset of 3, on the other hand, tells the oscilloscope to begin on the
third sample, then skip the number of samples specified by the sparsing factor (4). In this way, the sample rate is
effectively reduced.
For the sparsing factor (interval), you can set a value from 1 to 1,000,000 points. For the sparsing offset you can
set a value from 0 to 999,999.
Note: The maximum sparsing offset that can be entered for any sparsing factor equals Sparsing Factor 1
