Filters can only be adjusted when a correlation is not running. Any filter changes made will

become

active when a new correlation is started.

Only a single high/low pass filter is available for selection in EUREKA GO.

5.9.1

Low Filter Value

This shows the lower frequency limit of the filter. To change, drag the line to the required frequency.

The

low filter value must be 3Hz or above in addition to being below the high filter value.

As the value of the low filter is changed the range of frequencies shown as to be used for the correlation on the frequency
spectrum display will change.

5.9.2

High Filter Value

This shows the higher frequency limit of the filter. To change, drag the line to the required frequency.
