Description 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 Section 3 for
details.

Line 10 Sets the noise tolerance to ±20%, and then queries the noise tolerance level.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the noise tolerance band (20).
