Sparse Function - Teledyne HDO9000 Operator's Manual

You can use the Up and Down buttons to set this value. To make fine increment changes,
deselect the "only by 2, 5..." checkbox.
4. In Half Width enter the width in taps of the filter.
5. To use a weighting function rather than an upsample factor, select it from Weighting. See
for more information about the functions. If using the Kaiser function, also enter the Beta
value.

Sparse Function

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, says to
retain only one out of every 4 samples. A Sparsing offset of 3, on the other hand, says 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.
