The digital filter function can remove unwanted
components, such as noise, from the desired

The filtering only functions during continuous
acquisition using either the Sample or Peak detect
mode.
The cut-off frequency range and step resolution of
the digital filter is expressed as a fraction of the
underlying sample rate, as shown below.
