Query state of auto filter
These commands are used to control auto filter for the specifed function. The configuration for
the filter is summarized in tables 2-9, 2-14 and 2-19.
Disabling auto filter has no effect on the currently programmed filter state and count.
The ONCE parameter is analogous to a momentary toggle switch. When ONCE is sent, the auto
filter turns on momentarily and then disables.

Each measurement function (except TEMP and FREQ) can utilize the advanced filter which
adds a noise tolerance window to the averaging algorithm. These commands are used to set the
noise tolerance level of the advanced filter for the specifed function. The :ADVanced[:STATe]
commands are used to enable or disable the advanced filter.
The noise tolerance level is expressed as a percent of the last averaged reading. In general, if the
noise is within this window, the reading is simply based on the normal averaging algorithm. If
a reading is outside this window, then the advanced averaging algorithm is used. See paragraph
2.9.1 for details.
