Response message: REP or MOV
These commands are used to select the type of averaging filter (REPeat or MOVing) for the
specified function. With the repeating filter selected and enabled, the instrument will simply
acquire and average a specified number of readings and display the result. This process
continues for each new group of readings.
With the moving filter selected and enabled, the instrument will acquire and average a specified
number of readings. Each subsequent new reading will then be added to the group while the
oldest reading will be discarded. With each new reading, the average is re-calculated and
displayed.
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 will disable auto filter.
