The number of readings that are averaged by the filter is set with the :AVERage:COUNt com-
mand. The :AVERage[:STATe] command is used to enable or disable the filter. Changing the
filter type disables auto filter.
PRINT #1, "output 16; :volt:dc:aver:tcon rep; tcon?" ' Select repeating
filter
PRINT #1, "enter 16" ' Get response from 2002

:COUNt? Query filter count
:COUNt? DEFault Query the *RST default filter count
:COUNt? MINimum Query the lowest allowable filter count
:COUNt? MAXimum Query the largest allowable filter count
These commands are used to specify the filter count. In general, the filter count is the number
of readings that are acquired and stored in the filter buffer for the averaging calculation. The
larger the filter count, the more filtering that is performed.

[:STATe]? Query state of digital filter
These commands are used to enable or disable the digital averaging filter for the specified func-
tion. When enabled, readings will be filtered according to how the filter is configured.
