Details
The filter count is the number of readings that are acquired and stored in the filter stack for the averaging
calculation. The larger the filter count, the more filtering that is performed.
This command is set for the selected function.
Example
smu.measure.func = smu.FUNC_DC_CURRENT
smu.measure.filter.count = 10
smu.measure.filter.type = smu.FILTER_MOVING_AVG
smu.measure.filter.enable = smu.ON
Set the measurement function to
current.
Set the averaging filter type to moving
average, with a filter count of 10.
Enable the averaging filter.

This command enables or disables the averaging filter. When this is enabled, the measurements for the selected
measurement function are averaged as set by the filter count and filter type.
Example
smu.measure.func = smu.FUNC_DC_CURRENT
smu.measure.filter.count = 10
smu.measure.filter.type = smu.FILTER_MOVING_AVG
smu.measure.filter.enable = smu.ON
Set the measurement function to
current.
Set the averaging filter type to moving
average, with a filter count of 10.
Enable the averaging filter.
