Filtering Data
Time and Orbit plot displays can be cleaned up by the use of band and/or shaft revolution filters. The two
filter pull-down lists reside just to the right of the buttons in the third toolbar [when counting the main
window toolbar as toolbar 1]. The first filter list allows the user to select a Band Filter. The second filter
list allows the user to filter data based on the number of shaft revolutions.
In the example below, the plot on the left is based on 10 revolutions of unfiltered data. The plot on the
right makes use of the same data from 10 revolutions, but also makes use of a 1x filter.
