Non-Periodic Noise Filters
On some survey sites, non-periodic noise sources (such as electric fences) may be present that could affect the collection, processing and quality of the recorded data sets.
In order to remove these effects, the user may choose the "Apply Non-Periodic Noise Filter" option from the "Acquire Data" menu, as shown below. This will apply the filter to the recorded data set and remove the non-periodic noise.
Warning - Once the non-periodic filter is applied it cannot be undone. The use of this filter will significantly degrade the resolution of the data set. This filter must only be used where absolutely nessary.
