Filter length
You specify the filter length using the following command:
[SENSe[1]:]AVERage:COUNt <numeric_value>
The range of values for the filter length is 1 to 1024. Specifying this command
disables automatic filter length selection. Increasing the value of the filter length
reduces measurement noise. However, the time to take the measurement is
increased.
