Parameters

Count+ Output, Read-only, Placeholder (special (count & timestamp))
6 = Encoder 1
Filter Size Internal Parameter, Read-write, Enumerated (signed 16-bit integer)

This is the sample size for the filter. A larger size provides more filtering and a slower response. Note that large filter sizes can be very slow - e.g. 4096 @ 5ms timebase is over 20 seconds.
